Version 3.1.1-dev
-----------------
Nothing yet.
Version 3.1.0 (2017-07-28)
--------------------------
### Added
* [PHP 7.2] Added support for trailing comma in group use statements.
* [PHP 7.2] Added support for `object` type. This means `object` types will now be represented as a
builtin type (a simple `"object"` string), rather than a class `Name`.
### Fixed
* Floating-point numbers are now printed correctly if the LC_NUMERIC locale uses a comma as decimal
separator.
### Changed
* `Name::$parts` is no longer deprecated.
Version 3.0.6 (2017-06-28)
--------------------------
### Fixed
* Fixed the spelling of `Class_::VISIBILITY_MODIFIER_MASK`. The previous spelling of
`Class_::VISIBILITY_MODIFER_MASK` is preserved for backwards compatibility.
* The pretty printing will now preserve comments inside array literals and function calls by
printing the array items / function arguments on separate lines. Array literals and functions that
do not contain comments are not affected.
### Added
* Added `Builder\Param::makeVariadic()`.
### Deprecated
* The `Node::setLine()` method has been deprecated.
Version 3.0.5 (2017-03-05)
--------------------------
### Fixed
* Name resolution of `NullableType`s is now performed earlier, so that a fully resolved signature is
available when a function is entered. (#360)
* `Error` nodes are now considered empty, while previously they extended until the token where the
error occurred. This made some nodes larger than expected. (#359)
* Fixed notices being thrown during error recovery in some situations. (#362)
Version 3.0.4 (2017-02-10)
--------------------------
### Fixed
* Fixed some extensibility issues in pretty printer (`pUseType()` is now public and `pPrec()` calls
into `p()`, instead of directly dispatching to the type-specific printing method).
* Fixed notice in `bin/php-parse` script.
### Added
* Error recovery from missing semicolons is now supported in more cases.
* Error recovery from trailing commas in positions where PHP does not support them is now supported.
Version 3.0.3 (2017-02-03)
--------------------------
### Fixed
* In `"$foo[0]"` the `0` is now parsed as an `LNumber` rather than `String`. (#325)
* Ensure integers and floats are always pretty printed preserving semantics, even if the particular
value can only be manually constructed.
* Throw a `LogicException` when trying to pretty-print an `Error` node. Previously this resulted in
an undefined method exception or fatal error.
### Added
* [PHP 7.1] Added support for negative interpolated offsets: `"$foo[-1]"`
* Added `preserveOriginalNames` option to `NameResolver`. If this option is enabled, an
`originalName` attribute, containing the unresolved name, will be added to each resolved name.
* Added `php-parse --with-positions` option, which dumps nodes with position information.
### Deprecated
* The XML serializer has been deprecated. In particular, the classes `Serializer\XML`,
`Unserializer\XML`, as well as the interfaces `Serializer` and `Unserializer` are deprecated.
Version 3.0.2 (2016-12-06)
--------------------------
### Fixed
* Fixed name resolution of nullable types. (#324)
* Fixed pretty-printing of nullable types.
Version 3.0.1 (2016-12-01)
--------------------------
### Fixed
* Fixed handling of nested `list()`s: If the nested list was unkeyed, it was directly included in
the list items. If it was keyed, it was wrapped in `ArrayItem`. Now nested `List_` nodes are
always wrapped in `ArrayItem`s. (#321)
Version 3.0.0 (2016-11-30)
--------------------------
### Added
* Added support for dumping node positions in the NodeDumper through the `dumpPositions` option.
* Added error recovery support for `$`, `new`, `Foo::`.
Version 3.0.0-beta2 (2016-10-29)
--------------------------------
This release primarily improves our support for error recovery.
### Added
* Added `Node::setDocComment()` method.
* Added `Error::getMessageWithColumnInfo()` method.
* Added support for recovery from lexer errors.
* Added support for recovering from "special" errors (i.e. non-syntax parse errors).
* Added precise location information for lexer errors.
* Added `ErrorHandler` interface, and `ErrorHandler\Throwing` and `ErrorHandler\Collecting` as
specific implementations. These provide a general mechanism for handling error recovery.
* Added optional `ErrorHandler` argument to `Parser::parse()`, `Lexer::startLexing()` and
`NameResolver::__construct()`.
* The `NameResolver` now adds a `namespacedName` attribute on name nodes that cannot be statically
resolved (unqualified unaliased function or constant names in namespaces).
### Fixed
* Fixed attribute assignment for `GroupUse` prefix and variables in interpolated strings.
### Changed
* The constants on `NameTraverserInterface` have been moved into the `NameTraverser` class.
* Due to the error handling changes, the `Parser` interface and `Lexer` API have changed.
* The emulative lexer now directly postprocesses tokens, instead of using `~__EMU__~` sequences.
This changes the protected API of the lexer.
* The `Name::slice()` method now returns `null` for empty slices, previously `new Name([])` was
used. `Name::concat()` now also supports concatenation with `null`.
### Removed
* Removed `Name::append()` and `Name::prepend()`. These mutable methods have been superseded by
the immutable `Name::concat()`.
* Removed `Error::getRawLine()` and `Error::setRawLine()`. These methods have been superseded by
`Error::getStartLine()` and `Error::setStartLine()`.
* Removed support for node cloning in the `NodeTraverser`.
* Removed `$separator` argument from `Name::toString()`.
* Removed `throw_on_error` parser option and `Parser::getErrors()` method. Use the `ErrorHandler`
mechanism instead.
Version 3.0.0-beta1 (2016-09-16)
--------------------------------
### Added
* [7.1] Function/method and parameter builders now support PHP 7.1 type hints (void, iterable and
nullable types).
* Nodes and Comments now implement `JsonSerializable`. The node kind is stored in a `nodeType`
property.
* The `InlineHTML` node now has an `hasLeadingNewline` attribute, that specifies whether the
preceding closing tag contained a newline. The pretty printer honors this attribute.
* Partial parsing of `$obj->` (with missing property name) is now supported in error recovery mode.
* The error recovery mode is now exposed in the `php-parse` script through the `--with-recovery`
or `-r` flags.
The following changes are also part of PHP-Parser 2.1.1:
* The PHP 7 parser will now generate a parse error for `$var =& new Obj` assignments.
* Comments on free-standing code blocks will now be retained as comments on the first statement in
the code block.
Version 3.0.0-alpha1 (2016-07-25)
---------------------------------
### Added
* [7.1] Added support for `void` and `iterable` types. These will now be represented as strings
(instead of `Name` instances) similar to other builtin types.
* [7.1] Added support for class constant visibility. The `ClassConst` node now has a `flags` subnode
holding the visibility modifier, as well as `isPublic()`, `isProtected()` and `isPrivate()`
methods. The constructor changed to accept the additional subnode.
* [7.1] Added support for nullable types. These are represented using a new `NullableType` node
with a single `type` subnode.
* [7.1] Added support for short array destructuring syntax. This means that `Array` nodes may now
appear as the left-hand-side of assignments and foreach value targets. Additionally the array
items may now contain `null` values if elements are skipped.
* [7.1] Added support for keys in list() destructuring. The `List` subnode `vars` has been renamed
to `items` and now contains `ArrayItem`s instead of plain variables.
* [7.1] Added support for multi-catch. The `Catch` subnode `type` has been renamed to `types` and
is now an array of `Name`s.
* `Name::slice()` now supports lengths and negative offsets. This brings it in line with
`array_slice()` functionality.
### Changed
Due to PHP 7.1 support additions described above, the node structure changed as follows:
* `void` and `iterable` types are now stored as strings if the PHP 7 parser is used.
* The `ClassConst` constructor changed to accept an additional `flags` subnode.
* The `Array` subnode `items` may now contain `null` elements (destructuring).
* The `List` subnode `vars` has been renamed to `items` and now contains `ArrayItem`s instead of
plain variables.
* The `Catch` subnode `type` has been renamed to `types` and is now an array of `Name`s.
Additionally the following changes were made:
* The `type` subnode on `Class`, `ClassMethod` and `Property` has been renamed to `flags`. The
`type` subnode has retained for backwards compatibility and is populated to the same value as
`flags`. However, writes to `type` will not update `flags`.
* The `TryCatch` subnode `finallyStmts` has been replaced with a `finally` subnode that holds an
explicit `Finally` node. This allows for more accurate attribute assignment.
* The `Trait` constructor now has the same form as the `Class` and `Interface` constructors: It
takes an array of subnodes. Unlike classes/interfaces, traits can only have a `stmts` subnode.
* The `NodeDumper` now prints class/method/property/constant modifiers, as well as the include and
use type in a textual representation, instead of only showing the number.
* All methods on `PrettyPrinter\Standard` are now protected. Previoulsy most of them were public.
### Removed
* Removed support for running on PHP 5.4. It is however still possible to parse PHP 5.2-5.4 code
while running on a newer version.
* The deprecated `Comment::setLine()` and `Comment::setText()` methods have been removed.
* The deprecated `Name::set()`, `Name::setFirst()` and `Name::setLast()` methods have been removed.
Version 2.1.1 (2016-09-16)
--------------------------
### Changed
* The pretty printer will now escape all control characters in the range `\x00-\x1F` inside double
quoted strings. If no special escape sequence is available, an octal escape will be used.
* The quality of the error recovery has been improved. In particular unterminated expressions should
be handled more gracefully.
* The PHP 7 parser will now generate a parse error for `$var =& new Obj` assignments.
* Comments on free-standing code blocks will no be retained as comments on the first statement in
the code block.
Version 2.1.0 (2016-04-19)
--------------------------
### Fixed
* Properly support `B""` strings (with uppercase `B`) in a number of places.
* Fixed reformatting of indented parts in a certain non-standard comment style.
### Added
* Added `dumpComments` option to node dumper, to enable dumping of comments associated with nodes.
* Added `Stmt\Nop` node, that is used to collect comments located at the end of a block or at the
end of a file (without a following node with which they could otherwise be associated).
* Added `kind` attribute to `Expr\Exit` to distinguish between `exit` and `die`.
* Added `kind` attribute to `Scalar\LNumber` to distinguish between decimal, binary, octal and
hexadecimal numbers.
* Added `kind` attribtue to `Expr\Array` to distinguish between `array()` and `[]`.
* Added `kind` attribute to `Scalar\String` and `Scalar\Encapsed` to distinguish between
single-quoted, double-quoted, heredoc and nowdoc string.
* Added `docLabel` attribute to `Scalar\String` and `Scalar\Encapsed`, if it is a heredoc or
nowdoc string.
* Added start file offset information to `Comment` nodes.
* Added `setReturnType()` method to function and method builders.
* Added `-h` and `--help` options to `php-parse` script.
### Changed
* Invalid octal literals now throw a parse error in PHP 7 mode.
* The pretty printer takes all the new attributes mentioned in the previous section into account.
* The protected `AbstractPrettyPrinter::pComments()` method no longer returns a trailing newline.
* The bundled autoloader supports library files being stored in a different directory than
`PhpParser` for easier downstream distribution.
### Deprecated
* The `Comment::setLine()` and `Comment::setText()` methods have been deprecated. Construct new
objects instead.
### Removed
* The internal (but public) method `Scalar\LNumber::parse()` has been removed. A non-internal
`LNumber::fromString()` method has been added instead.
Version 2.0.1 (2016-02-28)
--------------------------
### Fixed
* `declare() {}` and `declare();` are not semantically equivalent and will now result in different
ASTs. The format case will have an empty `stmts` array, while the latter will set `stmts` to
`null`.
* Magic constants are now supported as semi-reserved keywords.
* A shebang line like `#!/usr/bin/env php` is now allowed at the start of a namespaced file.
Previously this generated an exception.
* The `prettyPrintFile()` method will not strip a trailing `?>` from the raw data that follows a
`__halt_compiler()` statement.
* The `prettyPrintFile()` method will not strip an opening `<?php` if the file starts with a
comment followed by InlineHTML.
Version 2.0.0 (2015-12-04)
--------------------------
### Changed
* String parts of encapsed strings are now represented using `Scalar\EncapsStringPart` nodes.
Previously raw strings were used. This affects the `parts` child of `Scalar\Encaps` and
`Expr\ShellExec`. The change has been done to allow assignment of attributes to encapsed string
parts.
Version 2.0.0-beta1 (2015-10-21)
--------------------------------
### Fixed
* Fixed issue with too many newlines being stripped at the end of heredoc/nowdoc strings in some
cases. (#227)
### Changed
* Update group use support to be in line with recent PHP 7.0 builds.
* Renamed `php-parse.php` to `php-parse` and registered it as a composer bin.
* Use composer PSR-4 autoloader instead of custom autoloader.
* Specify phpunit as a dev dependency.
### Added
* Added `shortArraySyntax` option to pretty printer, to print all arrays using short syntax.
Version 2.0.0-alpha1 (2015-07-14)
---------------------------------
A more detailed description of backwards incompatible changes can be found in the
[upgrading guide](UPGRADE-2.0.md).
### Removed
* Removed support for running on PHP 5.3. It is however still possible to parse PHP 5.2 and PHP 5.3
code while running on a newer version.
* Removed legacy class name aliases. This includes the old non-namespaced class names and the old
names for classes that were renamed for PHP 7 compatibility.
* Removed support for legacy node format. All nodes must have a `getSubNodeNames()` method now.
### Added
* Added support for remaining PHP 7 features that were not present in 1.x:
* Group use declarations. These are represented using `Stmt\GroupUse` nodes. Furthermore a `type`
attribute was added to `Stmt\UseUse` to handle mixed group use declarations.
* Uniform variable syntax.
* Generalized yield operator.
* Scalar type declarations. These are presented using `'bool'`, `'int'`, `'float'` and `'string'`
as the type. The PHP 5 parser also accepts these, however they'll be `Name` instances there.
* Unicode escape sequences.
* Added `PhpParser\ParserFactory` class, which should be used to create parser instances.
* Added `Name::concat()` which concatenates two names.
* Added `Name->slice()` which takes a subslice of a name.
### Changed
* `PhpParser\Parser` is now an interface, implemented by `Parser\Php5`, `Parser\Php7` and
`Parser\Multiple`. The `Multiple` parser will try multiple parsers, until one succeeds.
* Token constants are now defined on `PhpParser\Parser\Tokens` rather than `PhpParser\Parser`.
* The `Name->set()`, `Name->append()`, `Name->prepend()` and `Name->setFirst()` methods are
deprecated in favor of `Name::concat()` and `Name->slice()`.
* The `NodeTraverser` no longer clones nodes by default. The old behavior can be restored by
passing `true` to the constructor.
* The constructor for `Scalar` nodes no longer has a default value. E.g. `new LNumber()` should now
be written as `new LNumber(0)`.

Features
--------
In a Nutshell
-------------
The main features provided by this library are:
The parser turns PHP source code into an abstract syntax tree. For example, if you pass the following code into the
parser:
* Parsing PHP 5, PHP 7, and PHP 8 code into an abstract syntax tree (AST).
* Invalid code can be parsed into a partial AST.
* The AST contains accurate location information.
* Dumping the AST in human-readable form.
* Converting an AST back to PHP code.
* Experimental: Formatting can be preserved for partially changed ASTs.
* Infrastructure to traverse and modify ASTs.
* Resolution of namespaced names.
* Evaluation of constant expressions.
* Builders to simplify AST construction for code generation.
* Converting an AST into JSON and back.
Quick Start
-----------
Install the library using [composer](https://getcomposer.org):
php composer.phar require nikic/php-parser
Parse some PHP code into an AST and dump the result in human-readable form:
```php
<?php
echo 'Hi', 'World';
hello\world('foo', 'bar' . 'baz');
use PhpParser\Error;
use PhpParser\NodeDumper;
use PhpParser\ParserFactory;
$code = <<<'CODE'
<?php
function test($foo)
{
var_dump($foo);
}
CODE;
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
try {
$ast = $parser->parse($code);
} catch (Error $error) {
echo "Parse error: {$error->getMessage()}\n";
return;
}
$dumper = new NodeDumper;
echo $dumper->dump($ast) . "\n";
```
You'll get a syntax tree looking roughly like this:
This dumps an AST looking something like this:
```php
```
array(
0: Stmt_Echo(
exprs: array(
0: Scalar_String(
value: Hi
)
1: Scalar_String(
value: World
0: Stmt_Function(
byRef: false
name: Identifier(
name: test
)
params: array(
0: Param(
type: null
byRef: false
variadic: false
var: Expr_Variable(
name: foo
)
default: null
)
)
)
1: Expr_FuncCall(
name: Name(
parts: array(
0: hello
1: world
)
)
args: array(
0: Arg(
value: Scalar_String(
value: foo
)
byRef: false
)
1: Arg(
value: Expr_Concat(
left: Scalar_String(
value: bar
returnType: null
stmts: array(
0: Stmt_Expression(
expr: Expr_FuncCall(
name: Name(
parts: array(
0: var_dump
)
)
right: Scalar_String(
value: baz
args: array(
0: Arg(
value: Expr_Variable(
name: foo
)
byRef: false
unpack: false
)
)
)
byRef: false
)
)
)
)
```
You can then work with this syntax tree, for example to statically analyze the code (e.g. to find
programming errors or security issues).
Let's traverse the AST and perform some kind of modification. For example, drop all function bodies:
Additionally, you can convert a syntax tree back to PHP code. This allows you to do code preprocessing
(like automatedly porting code to older PHP versions).
```php
use PhpParser\Node;
use PhpParser\Node\Stmt\Function_;
use PhpParser\NodeTraverser;
use PhpParser\NodeVisitorAbstract;
Installation
------------
$traverser = new NodeTraverser();
$traverser->addVisitor(new class extends NodeVisitorAbstract {
public function enterNode(Node $node) {
if ($node instanceof Function_) {
// Clean out the function body
$node->stmts = [];
}
}
});
The preferred installation method is [composer](https://getcomposer.org):
$ast = $traverser->traverse($ast);
echo $dumper->dump($ast) . "\n";
```
php composer.phar require nikic/php-parser
This gives us an AST where the `Function_::$stmts` are empty:
```
array(
0: Stmt_Function(
byRef: false
name: Identifier(
name: test
)
params: array(
0: Param(
type: null
byRef: false
variadic: false
var: Expr_Variable(
name: foo
)
default: null
)
)
returnType: null
stmts: array(
)
)
)
```
Finally, we can convert the new AST back to PHP code:
```php
use PhpParser\PrettyPrinter;
$prettyPrinter = new PrettyPrinter\Standard;
echo $prettyPrinter->prettyPrintFile($ast);
```
This gives us our original code, minus the `var_dump()` call inside the function:
```php
<?php
function test($foo)
{
}
```

Upgrading from PHP-Parser 0.9 to 1.0
====================================
### PHP version requirements
PHP-Parser now requires PHP 5.3 or newer to run. It is however still possible to *parse* PHP 5.2 source code, while
running on a newer version.
### Move to namespaced names
The library has been moved to use namespaces with the `PhpParser` vendor prefix. However, the old names using
underscores are still available as aliases, as such most code should continue running on the new version without
further changes.
Old (still works, but discouraged):
```php
$parser = new \PHPParser_Parser(new \PHPParser_Lexer_Emulative);
$prettyPrinter = new \PHPParser_PrettyPrinter_Default;
```
New:
```php
$parser = new \PhpParser\Parser(new PhpParser\Lexer\Emulative);
$prettyPrinter = new \PhpParser\PrettyPrinter\Standard;
```
Note that the `PHPParser` prefix was changed to `PhpParser`. While PHP class names are technically case-insensitive,
the autoloader will not be able to load `PHPParser\Parser` or other case variants.
Due to conflicts with reserved keywords, some class names now end with an underscore, e.g. `PHPParser_Node_Stmt_Class`
is now `PhpParser\Node\Stmt\Class_`. (But as usual, the old name is still available.)
### Changes to `Node::getType()`
The `Node::getType()` method continues to return names using underscores instead of namespace separators and also does
not contain the trailing underscore that may be present in the class name. As such its output will not change in many
cases.
However, some node classes have been moved to a different namespace or renamed, which will result in a different
`Node::getType()` output:
```
Expr_AssignBitwiseAnd => Expr_AssignOp_BitwiseAnd
Expr_AssignBitwiseOr => Expr_AssignOp_BitwiseOr
Expr_AssignBitwiseXor => Expr_AssignOp_BitwiseXor
Expr_AssignConcat => Expr_AssignOp_Concat

Expr_AssignShiftRight => Expr_AssignOp_ShiftRight

Expr_Mul => Expr_BinaryOp_Mul
Expr_NotEqual => Expr_BinaryOp_NotEqual

Scalar_LineConst => Scalar_MagicConst_Line
Scalar_MethodConst => Scalar_MagicConst_Method
Scalar_NSConst => Scalar_MagicConst_Namespace
Scalar_TraitConst => Scalar_MagicConst_Trait
```
These changes may affect custom pretty printers and code comparing the return value of `Node::getType()` to specific
strings.
### Miscellaneous
* The classes `Template` and `TemplateLoader` have been removed. You should use some other [code generation][code_gen]
project built on top of PHP-Parser instead.
* The `PrettyPrinterAbstract::pStmts()` method now emits a leading newline if the statement list is not empty.
Custom pretty printers should remove the explicit newline before `pStmts()` calls.
Old:
```php
public function pStmt_Trait(PHPParser_Node_Stmt_Trait $node) {
return 'trait ' . $node->name
. "\n" . '{' . "\n" . $this->pStmts($node->stmts) . "\n" . '}';
}
```
New:
```php
public function pStmt_Trait(Stmt\Trait_ $node) {
return 'trait ' . $node->name
. "\n" . '{' . $this->pStmts($node->stmts) . "\n" . '}';
}

Upgrading from PHP-Parser 1.x to 2.0
====================================
### PHP version requirements
PHP-Parser now requires PHP 5.4 or newer to run. It is however still possible to *parse* PHP 5.2 and
PHP 5.3 source code, while running on a newer version.
### Creating a parser instance
Parser instances should now be created through the `ParserFactory`. Old direct instantiation code
will not work, because the parser class was renamed.
Old:
```php
use PhpParser\Parser, PhpParser\Lexer;
$parser = new Parser(new Lexer\Emulative);
```
New:
```php
use PhpParser\ParserFactory;
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
```
The first argument to `ParserFactory` determines how different PHP versions are handled. The
possible values are:
* `ParserFactory::PREFER_PHP7`: Try to parse code as PHP 7. If this fails, try to parse it as PHP 5.
* `ParserFactory::PREFER_PHP5`: Try to parse code as PHP 5. If this fails, try to parse it as PHP 7.
* `ParserFactory::ONLY_PHP7`: Parse code as PHP 7.
* `ParserFactory::ONLY_PHP5`: Parse code as PHP 5.
For most practical purposes the difference between `PREFER_PHP7` and `PREFER_PHP5` is mainly whether
a scalar type hint like `string` will be stored as `'string'` (PHP 7) or as `new Name('string')`
(PHP 5).
To use a custom lexer, pass it as the second argument to the `create()` method:
```php
use PhpParser\ParserFactory;
$lexer = new MyLexer;
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7, $lexer);
```
### Rename of the `PhpParser\Parser` class
`PhpParser\Parser` is now an interface, which is implemented by `Parser\Php5`, `Parser\Php7` and
`Parser\Multiple`. Parser tokens are now defined in `Parser\Tokens`. If you use the `ParserFactory`
described above to create your parser instance, these changes should have no further impact on you.
### Removal of legacy aliases
All legacy aliases for classes have been removed. This includes the old non-namespaced `PHPParser_`
classes, as well as the classes that had to be renamed for PHP 7 support.
### Deprecations
The `set()`, `setFirst()`, `append()` and `prepend()` methods of the `Node\Name` class have been
deprecated. Instead `Name::concat()` and `Name->slice()` should be used.
### Miscellaneous
* The `NodeTraverser` no longer clones nodes by default. If you want to restore the old behavior,
pass `true` to the constructor.
* The legacy node format has been removed. If you use custom nodes, they are now expected to
implement a `getSubNodeNames()` method.
* The default value for `Scalar` node constructors was removed. This means that something like
`new LNumber()` should be replaced by `new LNumber(0)`.
* String parts of encapsed strings are now represented using `Scalar\EncapsStringPart` nodes, while
previously raw strings were used. This affects the `parts` child of `Scalar\Encaps` and
`Expr\ShellExec`.

Upgrading from PHP-Parser 2.x to 3.0
====================================
The backwards-incompatible changes in this release may be summarized as follows:
* The specific details of the node representation have changed in some cases, primarily to
accomodate new PHP 7.1 features.
* There have been significant changes to the error recovery implementation. This may affect you,
if you used the error recovery mode or have a custom lexer implementation.
* A number of deprecated methods were removed.
### PHP version requirements
PHP-Parser now requires PHP 5.5 or newer to run. It is however still possible to *parse* PHP 5.2,
5.3 and 5.4 source code, while running on a newer version.
### Changes to the node structure
The following changes are likely to require code changes if the respective nodes are used:
* The `List` subnode `vars` has been renamed to `items` and now contains `ArrayItem`s instead of
plain variables.
* The `Catch` subnode `type` has been renamed to `types` and is now an array of `Name`s.
* The `TryCatch` subnode `finallyStmts` has been replaced with a `finally` subnode that holds an
explicit `Finally` node.
* The `type` subnode on `Class`, `ClassMethod` and `Property` has been renamed to `flags`. The
`type` subnode has retained for backwards compatibility and is populated to the same value as
`flags`. However, writes to `type` will not update `flags` and use of `type` is discouraged.
The following changes are unlikely to require code changes:
* The `ClassConst` constructor changed to accept an additional `flags` subnode.
* The `Trait` constructor now has the same form as the `Class` and `Interface` constructors: It
takes an array of subnodes. Unlike classes/interfaces, traits can only have a `stmts` subnode.
* The `Array` subnode `items` may now contain `null` elements (due to destructuring).
* `void` and `iterable` types are now stored as strings if the PHP 7 parser is used. Previously
these would have been represented as `Name` instances.
### Changes to error recovery mode
Previously, error recovery mode was enabled by setting the `throwOnError` option to `false` when
creating the parser, while collected errors were retrieved using the `getErrors()` method:
```php
$lexer = ...;
$parser = (new ParserFactory)->create(ParserFactor::ONLY_PHP7, $lexer, [
'throwOnError' => true,
]);
$stmts = $parser->parse($code);
$errors = $parser->getErrors();
if ($errors) {
handleErrors($errors);
}
processAst($stmts);
```
Both the `throwOnError` option and the `getErrors()` method have been removed in PHP-Parser 3.0.
Instead an instance of `ErrorHandler\Collecting` should be passed to the `parse()` method:
```php
$lexer = ...;
$parser = (new ParserFactory)->create(ParserFactor::ONLY_PHP7, $lexer);
$errorHandler = new ErrorHandler\Collecting;
$stmts = $parser->parse($code, $errorHandler);
if ($errorHandler->hasErrors()) {
handleErrors($errorHandler->getErrors());
}
processAst($stmts);
```
#### Multiple parser fallback in error recovery mode
As a result of this change, if a `Multiple` parser is used (e.g. through the `ParserFactory` using
`PREFER_PHP7` or `PREFER_PHP5`), it will now return the result of the first *non-throwing* parse. As
parsing never throws in error recovery mode, the result from the first parser will always be
returned.
The PHP 7 parser is a superset of the PHP 5 parser, with the exceptions that `=& new` and
`global $$foo->bar` are not supported (other differences are in representation only). The PHP 7
parser will be able to recover from the error in both cases. For this reason, this change will
likely pass unnoticed if you do not specifically test for this syntax.
It is possible to restore the precise previous behavior with the following code:
```php
$lexer = ...;
$parser7 = new Parser\Php7($lexer);
$parser5 = new Parser\Php5($lexer);
$errors7 = new ErrorHandler\Collecting();
$stmts7 = $parser7->parse($code, $errors7);
if ($errors7->hasErrors()) {
$errors5 = new ErrorHandler\Collecting();
$stmts5 = $parser5->parse($code, $errors5);
if (!$errors5->hasErrors()) {
// If PHP 7 parse has errors but PHP 5 parse has no errors, use PHP 5 result
return [$stmts5, $errors5];
}
}
// If PHP 7 succeeds or both fail use PHP 7 result
return [$stmts7, $errors7];
```
#### Error handling in the lexer
In order to support recovery from lexer errors, the signature of the `startLexing()` method changed
to optionally accept an `ErrorHandler`:
```php
// OLD
public function startLexing($code);
// NEW
public function startLexing($code, ErrorHandler $errorHandler = null);
```
If you use a custom lexer with overriden `startLexing()` method, it needs to be changed to accept
the extra parameter. The value should be passed on to the parent method.
#### Error checks in node constructors
The constructors of certain nodes used to contain additional checks for semantic errors, such as
creating a try block without either catch or finally. These checks have been moved from the node
constructors into the parser. This allows recovery from such errors, as well as representing the
resulting (invalid) AST.
This means that certain error conditions are no longer checked for manually constructed nodes.
### Removed methods, arguments, options
The following methods, arguments or options have been removed:
* `Comment::setLine()`, `Comment::setText()`: Create new `Comment` instances instead.
* `Name::set()`, `Name::setFirst()`, `Name::setLast()`, `Name::append()`, `Name::prepend()`:
Use `Name::concat()` in combination with `Name::slice()` instead.
* `Error::getRawLine()`, `Error::setRawLine()`. Use `Error::getStartLine()` and
`Error::setStartLine()` instead.
* `Parser::getErrors()`. Use `ErrorHandler\Collecting` instead.
* `$separator` argument of `Name::toString()`. Use `strtr()` instead, if you really need it.
* `$cloneNodes` argument of `NodeTraverser::__construct()`. Explicitly clone nodes in the visitor
instead.
* `throwOnError` parser option. Use `ErrorHandler\Collecting` instead.
### Miscellaneous
* The `NameResolver` will now resolve unqualified function and constant names in the global
namespace into fully qualified names. For example `foo()` in the global namespace resolves to
`\foo()`. For names where no static resolution is possible, a `namespacedName` attribute is
added now, containing the namespaced variant of the name.
* All methods on `PrettyPrinter\Standard` are now protected. Previoulsy most of them were public.
The pretty printer should only be invoked using the `prettyPrint()`, `prettyPrintFile()` and
`prettyPrintExpr()` methods.
* The node dumper now prints numeric values that act as enums/flags in a string representation.
If node dumper results are used in tests, updates may be needed to account for this.
* The constants on `NameTraverserInterface` have been moved into the `NameTraverser` class.
* The emulative lexer now directly postprocesses tokens, instead of using `~__EMU__~` sequences.
This changes the protected API of the emulative lexer.
* The `Name::slice()` method now returns `null` for empty slices, previously `new Name([])` was
used. `Name::concat()` now also supports concatenation with `null`.

Introduction
============
This project is a PHP 5.2 to PHP 7.1 parser **written in PHP itself**.
What is this for?
-----------------
A parser is useful for [static analysis][0], manipulation of code and basically any other
application dealing with code programmatically. A parser constructs an [Abstract Syntax Tree][1]
(AST) of the code and thus allows dealing with it in an abstract and robust way.
There are other ways of processing source code. One that PHP supports natively is using the
token stream generated by [`token_get_all`][2]. The token stream is much more low level than
the AST and thus has different applications: It allows to also analyze the exact formatting of
a file. On the other hand the token stream is much harder to deal with for more complex analysis.
For example an AST abstracts away the fact that in PHP variables can be written as `$foo`, but also
as `$$bar`, `${'foobar'}` or even `${!${''}=barfoo()}`. You don't have to worry about recognizing
all the different syntaxes from a stream of tokens.
Another question is: Why would I want to have a PHP parser *written in PHP*? Well, PHP might not be
a language especially suited for fast parsing, but processing the AST is much easier in PHP than it
would be in other, faster languages like C. Furthermore the people most probably wanting to do
programmatic PHP code analysis are incidentally PHP developers, not C developers.
What can it parse?
------------------
The parser supports parsing PHP 5.2-5.6 and PHP 7.
As the parser is based on the tokens returned by `token_get_all` (which is only able to lex the PHP
version it runs on), additionally a wrapper for emulating tokens from newer versions is provided.
This allows to parse PHP 7.1 source code running on PHP 5.5, for example. This emulation is somewhat
hacky and not perfect, but it should work well on any sane code.
What output does it produce?
----------------------------
The parser produces an [Abstract Syntax Tree][1] (AST) also known as a node tree. How this looks like
can best be seen in an example. The program `<?php echo 'Hi', 'World';` will give you a node tree
roughly looking like this:
```
array(
0: Stmt_Echo(
exprs: array(
0: Scalar_String(
value: Hi
)
1: Scalar_String(
value: World
)
)
)
)
```
This matches the structure of the code: An echo statement, which takes two strings as expressions,
with the values `Hi` and `World!`.
You can also see that the AST does not contain any whitespace information (but most comments are saved).
So using it for formatting analysis is not possible.
What else can it do?
--------------------
Apart from the parser itself this package also bundles support for some other, related features:
* Support for pretty printing, which is the act of converting an AST into PHP code. Please note
that "pretty printing" does not imply that the output is especially pretty. It's just how it's
called ;)
* Support for serializing and unserializing the node tree to XML
* Support for dumping the node tree in a human readable form (see the section above for an
example of how the output looks like)
* Infrastructure for traversing and changing the AST (node traverser and node visitors)
* A node visitor for resolving namespaced names

Usage of basic components
=========================
This document explains how to use the parser, the pretty printer and the node traverser.
Bootstrapping
-------------
To bootstrap the library, include the autoloader generated by composer:
```php
require 'path/to/vendor/autoload.php';
```
Additionally you may want to set the `xdebug.max_nesting_level` ini option to a higher value:
```php
ini_set('xdebug.max_nesting_level', 3000);
```
This ensures that there will be no errors when traversing highly nested node trees. However, it is
preferable to disable XDebug completely, as it can easily make this library more than five times
slower.
Parsing
-------
In order to parse code, you first have to create a parser instance:
```php
use PhpParser\ParserFactory;
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
```
The factory accepts a kind argument, that determines how different PHP versions are treated:
Kind | Behavior
-----|---------
`ParserFactory::PREFER_PHP7` | Try to parse code as PHP 7. If this fails, try to parse it as PHP 5.
`ParserFactory::PREFER_PHP5` | Try to parse code as PHP 5. If this fails, try to parse it as PHP 7.
`ParserFactory::ONLY_PHP7` | Parse code as PHP 7.
`ParserFactory::ONLY_PHP5` | Parse code as PHP 5.
Unless you have strong reason to use something else, `PREFER_PHP7` is a reasonable default.
The `create()` method optionally accepts a `Lexer` instance as the second argument. Some use cases
that require customized lexers are discussed in the [lexer documentation](component/Lexer.markdown).
Subsequently you can pass PHP code (including the opening `<?php` tag) to the `parse` method in order to
create a syntax tree. If a syntax error is encountered, an `PhpParser\Error` exception will be thrown:
```php
use PhpParser\Error;
use PhpParser\ParserFactory;
$code = '<?php // some code';
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
try {
$stmts = $parser->parse($code);
// $stmts is an array of statement nodes
} catch (Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
A parser instance can be reused to parse multiple files.
Node tree
---------
If you use the above code with `$code = "<?php echo 'Hi ', hi\\getTarget();"` the parser will
generate a node tree looking like this:
```
array(
0: Stmt_Echo(
exprs: array(
0: Scalar_String(
value: Hi
)
1: Expr_FuncCall(
name: Name(
parts: array(
0: hi
1: getTarget
)
)
args: array(
)
)
)
)
)
```
Thus `$stmts` will contain an array with only one node, with this node being an instance of
`PhpParser\Node\Stmt\Echo_`.
As PHP is a large language there are approximately 140 different nodes. In order to make work
with them easier they are grouped into three categories:
* `PhpParser\Node\Stmt`s are statement nodes, i.e. language constructs that do not return
a value and can not occur in an expression. For example a class definition is a statement.
It doesn't return a value and you can't write something like `func(class A {});`.
* `PhpParser\Node\Expr`s are expression nodes, i.e. language constructs that return a value
and thus can occur in other expressions. Examples of expressions are `$var`
(`PhpParser\Node\Expr\Variable`) and `func()` (`PhpParser\Node\Expr\FuncCall`).
* `PhpParser\Node\Scalar`s are nodes representing scalar values, like `'string'`
(`PhpParser\Node\Scalar\String_`), `0` (`PhpParser\Node\Scalar\LNumber`) or magic constants
like `__FILE__` (`PhpParser\Node\Scalar\MagicConst\File`). All `PhpParser\Node\Scalar`s extend
`PhpParser\Node\Expr`, as scalars are expressions, too.
* There are some nodes not in either of these groups, for example names (`PhpParser\Node\Name`)
and call arguments (`PhpParser\Node\Arg`).
Some node class names have a trailing `_`. This is used whenever the class name would otherwise clash
with a PHP keyword.
Every node has a (possibly zero) number of subnodes. You can access subnodes by writing
`$node->subNodeName`. The `Stmt\Echo_` node has only one subnode `exprs`. So in order to access it
in the above example you would write `$stmts[0]->exprs`. If you wanted to access the name of the function
call, you would write `$stmts[0]->exprs[1]->name`.
All nodes also define a `getType()` method that returns the node type. The type is the class name
without the `PhpParser\Node\` prefix and `\` replaced with `_`. It also does not contain a trailing
`_` for reserved-keyword class names.
It is possible to associate custom metadata with a node using the `setAttribute()` method. This data
can then be retrieved using `hasAttribute()`, `getAttribute()` and `getAttributes()`.
By default the lexer adds the `startLine`, `endLine` and `comments` attributes. `comments` is an array
of `PhpParser\Comment[\Doc]` instances.
The start line can also be accessed using `getLine()`/`setLine()` (instead of `getAttribute('startLine')`).
The last doc comment from the `comments` attribute can be obtained using `getDocComment()`.
Pretty printer
--------------
The pretty printer component compiles the AST back to PHP code. As the parser does not retain formatting
information the formatting is done using a specified scheme. Currently there is only one scheme available,
namely `PhpParser\PrettyPrinter\Standard`.
```php
use PhpParser\Error;
use PhpParser\ParserFactory;
use PhpParser\PrettyPrinter;
$code = "<?php echo 'Hi ', hi\\getTarget();";
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
$prettyPrinter = new PrettyPrinter\Standard;
try {
// parse
$stmts = $parser->parse($code);
// change
$stmts[0] // the echo statement
->exprs // sub expressions
[0] // the first of them (the string node)
->value // it's value, i.e. 'Hi '
= 'Hello '; // change to 'Hello '
// pretty print
$code = $prettyPrinter->prettyPrint($stmts);
echo $code;
} catch (Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
The above code will output:
<?php echo 'Hello ', hi\getTarget();
As you can see the source code was first parsed using `PhpParser\Parser->parse()`, then changed and then
again converted to code using `PhpParser\PrettyPrinter\Standard->prettyPrint()`.
The `prettyPrint()` method pretty prints a statements array. It is also possible to pretty print only a
single expression using `prettyPrintExpr()`.
The `prettyPrintFile()` method can be used to print an entire file. This will include the opening `<?php` tag
and handle inline HTML as the first/last statement more gracefully.
Node traversation
-----------------
The above pretty printing example used the fact that the source code was known and thus it was easy to
write code that accesses a certain part of a node tree and changes it. Normally this is not the case.
Usually you want to change / analyze code in a generic way, where you don't know how the node tree is
going to look like.
For this purpose the parser provides a component for traversing and visiting the node tree. The basic
structure of a program using this `PhpParser\NodeTraverser` looks like this:
```php
use PhpParser\NodeTraverser;
use PhpParser\ParserFactory;
use PhpParser\PrettyPrinter;
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
$traverser = new NodeTraverser;
$prettyPrinter = new PrettyPrinter\Standard;
// add your visitor
$traverser->addVisitor(new MyNodeVisitor);
try {
$code = file_get_contents($fileName);
// parse
$stmts = $parser->parse($code);
// traverse
$stmts = $traverser->traverse($stmts);
// pretty print
$code = $prettyPrinter->prettyPrintFile($stmts);
echo $code;
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
The corresponding node visitor might look like this:
```php
use PhpParser\Node;
use PhpParser\NodeVisitorAbstract;
class MyNodeVisitor extends NodeVisitorAbstract
{
public function leaveNode(Node $node) {
if ($node instanceof Node\Scalar\String_) {
$node->value = 'foo';
}
}
}
```
The above node visitor would change all string literals in the program to `'foo'`.
All visitors must implement the `PhpParser\NodeVisitor` interface, which defines the following four
methods:
```php
public function beforeTraverse(array $nodes);
public function enterNode(\PhpParser\Node $node);
public function leaveNode(\PhpParser\Node $node);
public function afterTraverse(array $nodes);
```
The `beforeTraverse()` method is called once before the traversal begins and is passed the nodes the
traverser was called with. This method can be used for resetting values before traversation or
preparing the tree for traversal.
The `afterTraverse()` method is similar to the `beforeTraverse()` method, with the only difference that
it is called once after the traversal.
The `enterNode()` and `leaveNode()` methods are called on every node, the former when it is entered,
i.e. before its subnodes are traversed, the latter when it is left.
All four methods can either return the changed node or not return at all (i.e. `null`) in which
case the current node is not changed.
The `enterNode()` method can additionally return the value `NodeTraverser::DONT_TRAVERSE_CHILDREN`,
which instructs the traverser to skip all children of the current node.
The `leaveNode()` method can additionally return the value `NodeTraverser::REMOVE_NODE`, in which
case the current node will be removed from the parent array. Furthermore it is possible to return
an array of nodes, which will be merged into the parent array at the offset of the current node.
I.e. if in `array(A, B, C)` the node `B` should be replaced with `array(X, Y, Z)` the result will
be `array(A, X, Y, Z, C)`.
Instead of manually implementing the `NodeVisitor` interface you can also extend the `NodeVisitorAbstract`
class, which will define empty default implementations for all the above methods.
The NameResolver node visitor
-----------------------------
One visitor is already bundled with the package: `PhpParser\NodeVisitor\NameResolver`. This visitor
helps you work with namespaced code by trying to resolve most names to fully qualified ones.
For example, consider the following code:
use A as B;
new B\C();
In order to know that `B\C` really is `A\C` you would need to track aliases and namespaces yourself.
The `NameResolver` takes care of that and resolves names as far as possible.
After running it most names will be fully qualified. The only names that will stay unqualified are
unqualified function and constant names. These are resolved at runtime and thus the visitor can't
know which function they are referring to. In most cases this is a non-issue as the global functions
are meant.
Also the `NameResolver` adds a `namespacedName` subnode to class, function and constant declarations
that contains the namespaced name instead of only the shortname that is available via `name`.
Example: Converting namespaced code to pseudo namespaces
--------------------------------------------------------
A small example to understand the concept: We want to convert namespaced code to pseudo namespaces
so it works on 5.2, i.e. names like `A\\B` should be converted to `A_B`. Note that such conversions
are fairly complicated if you take PHP's dynamic features into account, so our conversion will
assume that no dynamic features are used.
We start off with the following base code:
```php
use PhpParser\ParserFactory;
use PhpParser\PrettyPrinter;
use PhpParser\NodeTraverser;
use PhpParser\NodeVisitor\NameResolver;
$inDir = '/some/path';
$outDir = '/some/other/path';
$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
$traverser = new NodeTraverser;
$prettyPrinter = new PrettyPrinter\Standard;
$traverser->addVisitor(new NameResolver); // we will need resolved names
$traverser->addVisitor(new NamespaceConverter); // our own node visitor
// iterate over all .php files in the directory
$files = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($inDir));
$files = new \RegexIterator($files, '/\.php$/');
foreach ($files as $file) {
try {
// read the file that should be converted
$code = file_get_contents($file);
// parse
$stmts = $parser->parse($code);
// traverse
$stmts = $traverser->traverse($stmts);
// pretty print
$code = $prettyPrinter->prettyPrintFile($stmts);
// write the converted file to the target directory
file_put_contents(
substr_replace($file->getPathname(), $outDir, 0, strlen($inDir)),
$code
);
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
}
```
Now lets start with the main code, the `NodeVisitor\NamespaceConverter`. One thing it needs to do
is convert `A\\B` style names to `A_B` style ones.
```php
use PhpParser\Node;
class NamespaceConverter extends \PhpParser\NodeVisitorAbstract
{
public function leaveNode(Node $node) {
if ($node instanceof Node\Name) {
return new Node\Name($node->toString('_'));
}
}
}
```
The above code profits from the fact that the `NameResolver` already resolved all names as far as
possible, so we don't need to do that. We only need to create a string with the name parts separated
by underscores instead of backslashes. This is what `$node->toString('_')` does. (If you want to
create a name with backslashes either write `$node->toString()` or `(string) $node`.) Then we create
a new name from the string and return it. Returning a new node replaces the old node.
Another thing we need to do is change the class/function/const declarations. Currently they contain
only the shortname (i.e. the last part of the name), but they need to contain the complete name including
the namespace prefix:
```php
use PhpParser\Node;
use PhpParser\Node\Stmt;
class NodeVisitor_NamespaceConverter extends \PhpParser\NodeVisitorAbstract
{
public function leaveNode(Node $node) {
if ($node instanceof Node\Name) {
return new Node\Name($node->toString('_'));
} elseif ($node instanceof Stmt\Class_
|| $node instanceof Stmt\Interface_
|| $node instanceof Stmt\Function_) {
$node->name = $node->namespacedName->toString('_');
} elseif ($node instanceof Stmt\Const_) {
foreach ($node->consts as $const) {
$const->name = $const->namespacedName->toString('_');
}
}
}
}
```
There is not much more to it than converting the namespaced name to string with `_` as separator.
The last thing we need to do is remove the `namespace` and `use` statements:
```php
use PhpParser\Node;
use PhpParser\Node\Stmt;
class NodeVisitor_NamespaceConverter extends \PhpParser\NodeVisitorAbstract
{
public function leaveNode(Node $node) {
if ($node instanceof Node\Name) {
return new Node\Name($node->toString('_'));
} elseif ($node instanceof Stmt\Class_
|| $node instanceof Stmt\Interface_
|| $node instanceof Stmt\Function_) {
$node->name = $node->namespacedName->toString('_');
} elseif ($node instanceof Stmt\Const_) {
foreach ($node->consts as $const) {
$const->name = $const->namespacedName->toString('_');
}
} elseif ($node instanceof Stmt\Namespace_) {
// returning an array merges is into the parent array
return $node->stmts;
} elseif ($node instanceof Stmt\Use_) {
// returning false removed the node altogether
return false;
}
}
}
```
That's all.

Other node tree representations
===============================
It is possible to convert the AST into several textual representations, which serve different uses.
Simple serialization
--------------------
It is possible to serialize the node tree using `serialize()` and also unserialize it using
`unserialize()`. The output is not human readable and not easily processable from anything
but PHP, but it is compact and generates quickly. The main application thus is in caching.
Human readable dumping
----------------------
Furthermore it is possible to dump nodes into a human readable format using the `dump` method of
`PhpParser\NodeDumper`. This can be used for debugging.
```php
$code = <<<'CODE'
<?php
function printLine($msg) {
echo $msg, "\n";
}
printLine('Hello World!!!');
CODE;
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7);
$nodeDumper = new PhpParser\NodeDumper;
try {
$stmts = $parser->parse($code);
echo $nodeDumper->dump($stmts), "\n";
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
The above script will have an output looking roughly like this:
```
array(
0: Stmt_Function(
byRef: false
params: array(
0: Param(
name: msg
default: null
type: null
byRef: false
)
)
stmts: array(
0: Stmt_Echo(
exprs: array(
0: Expr_Variable(
name: msg
)
1: Scalar_String(
value:
)
)
)
)
name: printLine
)
1: Expr_FuncCall(
name: Name(
parts: array(
0: printLine
)
)
args: array(
0: Arg(
value: Scalar_String(
value: Hello World!!!
)
byRef: false
)
)
)
)
```
JSON encoding
-------------
Nodes (and comments) implement the `JsonSerializable` interface. As such, it is possible to JSON
encode the AST directly using `json_encode()`:
```php
$code = <<<'CODE'
<?php
function printLine($msg) {
echo $msg, "\n";
}
printLine('Hello World!!!');
CODE;
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7);
$nodeDumper = new PhpParser\NodeDumper;
try {
$stmts = $parser->parse($code);
echo json_encode($stmts, JSON_PRETTY_PRINT), "\n";
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
This will result in the following output (which includes attributes):
```json
[
{
"nodeType": "Stmt_Function",
"byRef": false,
"name": "printLine",
"params": [
{
"nodeType": "Param",
"type": null,
"byRef": false,
"variadic": false,
"name": "msg",
"default": null,
"attributes": {
"startLine": 3,
"endLine": 3
}
}
],
"returnType": null,
"stmts": [
{
"nodeType": "Stmt_Echo",
"exprs": [
{
"nodeType": "Expr_Variable",
"name": "msg",
"attributes": {
"startLine": 4,
"endLine": 4
}
},
{
"nodeType": "Scalar_String",
"value": "\n",
"attributes": {
"startLine": 4,
"endLine": 4,
"kind": 2
}
}
],
"attributes": {
"startLine": 4,
"endLine": 4
}
}
],
"attributes": {
"startLine": 3,
"endLine": 5
}
},
{
"nodeType": "Expr_FuncCall",
"name": {
"nodeType": "Name",
"parts": [
"printLine"
],
"attributes": {
"startLine": 7,
"endLine": 7
}
},
"args": [
{
"nodeType": "Arg",
"value": {
"nodeType": "Scalar_String",
"value": "Hello World!!!",
"attributes": {
"startLine": 7,
"endLine": 7,
"kind": 1
}
},
"byRef": false,
"unpack": false,
"attributes": {
"startLine": 7,
"endLine": 7
}
}
],
"attributes": {
"startLine": 7,
"endLine": 7
}
}
]
```
There is currently no mechanism to convert JSON back into a node tree. Furthermore, not all ASTs
can be JSON encoded. In particular, JSON only supports UTF-8 strings.
Serialization to XML
--------------------
It is also possible to serialize the node tree to XML using `PhpParser\Serializer\XML->serialize()`
and to unserialize it using `PhpParser\Unserializer\XML->unserialize()`. This is useful for
interfacing with other languages and applications or for doing transformation using XSLT.
```php
<?php
$code = <<<'CODE'
<?php
function printLine($msg) {
echo $msg, "\n";
}
printLine('Hello World!!!');
CODE;
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7);
$serializer = new PhpParser\Serializer\XML;
try {
$stmts = $parser->parse($code);
echo $serializer->serialize($stmts);
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
Produces:

Code generation
===============
It is also possible to generate code using the parser, by first creating an Abstract Syntax Tree and then using the
pretty printer to convert it to PHP code. To simplify code generation, the project comes with builders which allow
creating node trees using a fluid interface, instead of instantiating all nodes manually. Builders are available for
the following syntactic elements:
* namespaces and use statements
* classes, interfaces and traits
* methods, functions and parameters
* properties
Here is an example:
```php
use PhpParser\BuilderFactory;
use PhpParser\PrettyPrinter;
use PhpParser\Node;
$factory = new BuilderFactory;
$node = $factory->namespace('Name\Space')
->addStmt($factory->use('Some\Other\Thingy')->as('SomeOtherClass'))
->addStmt($factory->class('SomeClass')
->extend('SomeOtherClass')
->implement('A\Few', '\Interfaces')
->makeAbstract() // ->makeFinal()
->addStmt($factory->method('someMethod')
->makePublic()
->makeAbstract() // ->makeFinal()
->setReturnType('bool')
->addParam($factory->param('someParam')->setTypeHint('SomeClass'))
->setDocComment('/**
* This method does something.
*
* @param SomeClass And takes a parameter
*/')
)
->addStmt($factory->method('anotherMethod')
->makeProtected() // ->makePublic() [default], ->makePrivate()
->addParam($factory->param('someParam')->setDefault('test'))
// it is possible to add manually created nodes
->addStmt(new Node\Expr\Print_(new Node\Expr\Variable('someParam')))
)
// properties will be correctly reordered above the methods
->addStmt($factory->property('someProperty')->makeProtected())
->addStmt($factory->property('anotherProperty')->makePrivate()->setDefault(array(1, 2, 3)))
)
->getNode()
;
$stmts = array($node);
$prettyPrinter = new PrettyPrinter\Standard();
echo $prettyPrinter->prettyPrintFile($stmts);
```
This will produce the following output with the standard pretty printer:
```php
<?php
namespace Name\Space;
use Some\Other\Thingy as SomeClass;
abstract class SomeClass extends SomeOtherClass implements A\Few, \Interfaces
{
protected $someProperty;
private $anotherProperty = array(1, 2, 3);
/**
* This method does something.
*
* @param SomeClass And takes a parameter
*/
public abstract function someMethod(SomeClass $someParam) : bool;
protected function anotherMethod($someParam = 'test')
{
print $someParam;
}
}
```

Error handling
==============
Errors during parsing or analysis are represented using the `PhpParser\Error` exception class. In addition to an error
message, an error can also store additional information about the location the error occurred at.
How much location information is available depends on the origin of the error and how many lexer attributes have been
enabled. At a minimum the start line of the error is usually available.
Column information
------------------
In order to receive information about not only the line, but also the column span an error occurred at, the file
position attributes in the lexer need to be enabled:
```php
$lexer = new PhpParser\Lexer(array(
'usedAttributes' => array('comments', 'startLine', 'endLine', 'startFilePos', 'endFilePos'),
));
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7, $lexer);
try {
$stmts = $parser->parse($code);
// ...
} catch (PhpParser\Error $e) {
// ...
}
```
Before using column information its availability needs to be checked with `$e->hasColumnInfo()`, as the precise
location of an error cannot always be determined. The methods for retrieving column information also have to be passed
the source code of the parsed file. An example for printing an error:
```php
if ($e->hasColumnInfo()) {
echo $e->getRawMessage() . ' from ' . $e->getStartLine() . ':' . $e->getStartColumn($code)
. ' to ' . $e->getEndLine() . ':' . $e->getEndColumn($code);
// or:
echo $e->getMessageWithColumnInfo();
} else {
echo $e->getMessage();
}
```
Both line numbers and column numbers are 1-based. EOF errors will be located at the position one past the end of the
file.
Error recovery
--------------
The error behavior of the parser (and other components) is controlled by an `ErrorHandler`. Whenever an error is
encountered, `ErrorHandler::handleError()` is invoked. The default error handling strategy is `ErrorHandler\Throwing`,
which will immediately throw when an error is encountered.
To instead collect all encountered errors into an array, while trying to continue parsing the rest of the source code,
an instance of `ErrorHandler\Collecting` can be passed to the `Parser::parse()` method. A usage example:
```php
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::ONLY_PHP7);
$errorHandler = new PhpParser\ErrorHandler\Collecting;
$stmts = $parser->parse($code, $errorHandler);
if ($errorHandler->hasErrors()) {
foreach ($errorHandler->getErrors() as $error) {
// $error is an ordinary PhpParser\Error
}
}
if (null !== $stmts) {
// $stmts is a best-effort partial AST
}
```
The `NameResolver` visitor also accepts an `ErrorHandler` as a constructor argument.

Lexer component documentation
=============================
The lexer is responsible for providing tokens to the parser. The project comes with two lexers: `PhpParser\Lexer` and
`PhpParser\Lexer\Emulative`. The latter is an extension of the former, which adds the ability to emulate tokens of
newer PHP versions and thus allows parsing of new code on older versions.
This documentation discusses options available for the default lexers and explains how lexers can be extended.
Lexer options
-------------
The two default lexers accept an `$options` array in the constructor. Currently only the `'usedAttributes'` option is
supported, which allows you to specify which attributes will be added to the AST nodes. The attributes can then be
accessed using `$node->getAttribute()`, `$node->setAttribute()`, `$node->hasAttribute()` and `$node->getAttributes()`
methods. A sample options array:
```php
$lexer = new PhpParser\Lexer(array(
'usedAttributes' => array(
'comments', 'startLine', 'endLine'
)
));
```
The attributes used in this example match the default behavior of the lexer. The following attributes are supported:
* `comments`: Array of `PhpParser\Comment` or `PhpParser\Comment\Doc` instances, representing all comments that occurred
between the previous non-discarded token and the current one. Use of this attribute is required for the
`$node->getDocComment()` method to work. The attribute is also needed if you wish the pretty printer to retain
comments present in the original code.
* `startLine`: Line in which the node starts. This attribute is required for the `$node->getLine()` to work. It is also
required if syntax errors should contain line number information.
* `endLine`: Line in which the node ends.
* `startTokenPos`: Offset into the token array of the first token in the node.
* `endTokenPos`: Offset into the token array of the last token in the node.
* `startFilePos`: Offset into the code string of the first character that is part of the node.
* `endFilePos`: Offset into the code string of the last character that is part of the node.
### Using token positions
The token offset information is useful if you wish to examine the exact formatting used for a node. For example the AST
does not distinguish whether a property was declared using `public` or using `var`, but you can retrieve this
information based on the token position:
```php
function isDeclaredUsingVar(array $tokens, PhpParser\Node\Stmt\Property $prop) {
$i = $prop->getAttribute('startTokenPos');
return $tokens[$i][0] === T_VAR;
}
```
In order to make use of this function, you will have to provide the tokens from the lexer to your node visitor using
code similar to the following:
```php
class MyNodeVisitor extends PhpParser\NodeVisitorAbstract {
private $tokens;
public function setTokens(array $tokens) {
$this->tokens = $tokens;
}
public function leaveNode(PhpParser\Node $node) {
if ($node instanceof PhpParser\Node\Stmt\Property) {
var_dump(isDeclaredUsingVar($this->tokens, $node));
}
}
}
$lexer = new PhpParser\Lexer(array(
'usedAttributes' => array(
'comments', 'startLine', 'endLine', 'startTokenPos', 'endTokenPos'
)
));
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7, $lexer);
$visitor = new MyNodeVisitor();
$traverser = new PhpParser\NodeTraverser();
$traverser->addVisitor($visitor);
try {
$stmts = $parser->parse($code);
$visitor->setTokens($lexer->getTokens());
$stmts = $traverser->traverse($stmts);
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
The same approach can also be used to perform specific modifications in the code, without changing the formatting in
other places (which is the case when using the pretty printer).
Lexer extension
---------------
A lexer has to define the following public interface:
void startLexing(string $code, ErrorHandler $errorHandler = null);
array getTokens();
string handleHaltCompiler();
int getNextToken(string &$value = null, array &$startAttributes = null, array &$endAttributes = null);
The `startLexing()` method is invoked with the source code that is to be lexed (including the opening tag) whenever the
`parse()` method of the parser is called. It can be used to reset state or preprocess the source code or tokens. The
passes `ErrorHandler` should be used to report lexing errors.
The `getTokens()` method returns the current token array, in the usual `token_get_all()` format. This method is not
used by the parser (which uses `getNextToken()`), but is useful in combination with the token position attributes.
The `handleHaltCompiler()` method is called whenever a `T_HALT_COMPILER` token is encountered. It has to return the
remaining string after the construct (not including `();`).
The `getNextToken()` method returns the ID of the next token (as defined by the `Parser::T_*` constants). If no more
tokens are available it must return `0`, which is the ID of the `EOF` token. Furthermore the string content of the
token should be written into the by-reference `$value` parameter (which will then be available as `$n` in the parser).
### Attribute handling
The other two by-ref variables `$startAttributes` and `$endAttributes` define which attributes will eventually be
assigned to the generated nodes: The parser will take the `$startAttributes` from the first token which is part of the
node and the `$endAttributes` from the last token that is part of the node.
E.g. if the tokens `T_FUNCTION T_STRING ... '{' ... '}'` constitute a node, then the `$startAttributes` from the
`T_FUNCTION` token will be taken and the `$endAttributes` from the `'}'` token.
An application of custom attributes is storing the exact original formatting of literals: While the parser does retain
some information about the formatting of integers (like decimal vs. hexadecimal) or strings (like used quote type), it
does not preserve the exact original formatting (e.g. leading zeros for integers or escape sequences in strings). This
can be remedied by storing the original value in an attribute:
```php
use PhpParser\Lexer;
use PhpParser\Parser\Tokens;
class KeepOriginalValueLexer extends Lexer // or Lexer\Emulative
{
public function getNextToken(&$value = null, &$startAttributes = null, &$endAttributes = null) {
$tokenId = parent::getNextToken($value, $startAttributes, $endAttributes);
if ($tokenId == Tokens::T_CONSTANT_ENCAPSED_STRING // non-interpolated string
|| $tokenId == Tokens::T_ENCAPSED_AND_WHITESPACE // interpolated string
|| $tokenId == Tokens::T_LNUMBER // integer
|| $tokenId == Tokens::T_DNUMBER // floating point number
) {
// could also use $startAttributes, doesn't really matter here
$endAttributes['originalValue'] = $value;
}
return $tokenId;
}
}
```

Building the parser
===================
In order to rebuild the parser, you need [moriyoshi's fork of kmyacc](https://github.com/moriyoshi/kmyacc-forked).
After you compiled/installed it, run the `rebuildParsers.php` script.
Run `php grammar/rebuildParsers.php` to rebuild the parsers. Additional options:
By default only the `Parser.php` is built. If you want to additionally emit debug symbols and create `y.output`, run the
script with `--debug`. If you want to retain the preprocessed grammar pass `--keep-tmp-grammar`.
* The `KMYACC` environment variable can be used to specify an alternative `kmyacc` binary.
By default the `phpyacc` dev dependency will be used. To use the original `kmyacc`, you
need to compile [moriyoshi's fork](https://github.com/moriyoshi/kmyacc-forked).
* The `--debug` option enables emission of debug symbols and creates the `y.output` file.
* The `--keep-tmp-grammar` option preserves the preprocessed grammar file.
