PHP-Parser 1.0.1

• Disallow new expressions without a class name. Previously new; was accidentally considered to be valid code.
• Support T_ONUMBER token used by HHVM.
• Add ability to directly pass code to the php-parse.php script.
• Prevent truncation of var_dump() output in the php-parse.php script if XDebug is used.

PHP-Parser 1.0.0

Upgrading from PHP-Parser 0.9 to 1.0

See migration guide.

Note: The 0.9.x branch is no longer supported.

Changes since version 0.9.x

The most important changes are:

• Complete support for parsing PHP 5.6.
• Dropped support for running on PHP 5.2 (while parsing PHP 5.2 on newer versions is still possible).
• Move to namespaced class names, e.g. PhpParser\Parser instead of PHPParser_Parser. The old names using underscored are still supported as aliases.

For a complete list of changes, see the Changelog.

Changes since 1.0.0 beta 2

• Removed deprecated Template and TemplateLoader classes.
• Fixed XML unserializer to properly work with new namespaced node names.

PHP-Parser 1.0.0 Beta 2

• [PHP 5.6] Updated support for constant scalar expressions to comply with latest changes. This means that arrays and array dimension fetches are now supported as well.
• [PHP 5.6] Direct array dereferencing of constants is supported now, i.e. both FOO[0] and Foo::BAR[0] are valid now.
• Fixed handling of special class names (self, parent and static) in the name resolver to be case insensitive. Additionally the name resolver now enforces that special class names are only used as unqualified names, e.g. \self is considered invalid.
• The case of references to the static class name is now preserved. Previously static was always lowercased, regardless of the case used in the source code.
• The autoloader now only requires a file if it exists. This allows usages like class_exists('PhpParser\NotExistingClass').
• Added experimental bin/php-parse.php script, which is intended to help exploring and debugging the node tree.
• Separated the parser implemention (in lib/PhpParser/ParserAbstract.php) and the generated data (in lib/PhpParser/Parser.php). Furthermore the parser now uses meaningful variable names and contains comments explaining their usage.

PHP-Parser 0.9.5

This is the last release on the 0.9 branch. All users on PHP >= 5.3 are encouraged to use version 1.0 instead, which is mostly compatible.

• Add NodeTraverser::removeVisitor() method, which removes a visitor from the node traverser. The method was not added to the corresponding NodeTraverserInterface to avoid BC breaks with custom traversers (it is added in version 1.0).
• Deprecated PHPParser_Template and PHPParser_TemplateLoader. This functionality does not belong in the main project and - as far as I know - nobody is using it.
• Fix alias resolution in NameResolver: Class names are now correctly handled as case-insensitive.
• The undefined variable error, which is used in the lexer to reset the error state, will no longer interfere with custom error handlers.
• Make lexer compatible with xdebug.scream.

PHP-Parser 1.0.0 Beta 1

• [BC] 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.

• [BC] 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.

  However, code performing dispatch operations on Node::getType() may be affected by some of the name changes. For example a + node will now return type Expr_BinaryOp_Plus instead of Expr_Plus. In particular this may affect custom pretty printers.

  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)

• [PHP 5.6] Added support for the power operator ** (node Expr\BinaryOp\Pow) and the compound power assignment operator **= (node Expr\AssignOp\Pow).

• [PHP 5.6] Added support for variadic functions: Param nodes now have variadic as a boolean subnode.

• [PHP 5.6] Added support for argument unpacking: Arg nodes now have unpack as a boolean subnode.

• [PHP 5.6] Added support for aliasing of functions and constants. Stmt\Use_ nodes now have an integral type subnode, which is one of Stmt\Use_::TYPE_NORMAL (use), Stmt\Use_::TYPE_FUNCTION (use function) or Stmt\Use_::TYPE_CONSTANT (use const).

  The NameResolver now also supports resolution of such aliases.

• [PHP 5.6] Added support for constant scalar expressions. This means that certain expressions are now allowed as the initializer for constants, properties, parameters, static variables, etc.

• [BC] Improved pretty printing of empty statements lists, which are now printed as {\n} instead of {\n \n}. This changes the behavior of the protected PrettyPrinterAbstract::pStmts() method, so custom pretty printing code making use it of may need to be adjusted.

• Changed the order of some subnodes to be consistent with their order in the sour code. For example Stmt\If->cond will now appear before Stmt\If->stmts etc.

• Added Scalar\MagicConstant->getName(), which returns the name of the magic constant (e.g. __CLASS__).

The following changes are also included in 0.9.5-dev:

• [BC] Deprecated PHPParser_Template and PHPParser_TemplateLoader. This functionality does not belong in the main project and - as far as I know - nobody is using it.
• Add NodeTraverser::removeVisitor() method, which removes a visitor from the node traverser. This also modifies the corresponding NodeTraverserInterface.
• Fix alias resolution in NameResolver: Class names are now correctly handled as case-insensitive.
• The undefined variable error, which is used to the lexer to reset the error state, will no longer interfere with custom error handlers.

PHP-Parser 0.9.4

• [PHP 5.5] Add support for ClassName::class. This is parsed as an Expr_ClassConstFetch with 'class' being the constant name.

• Syntax errors now include information on expected tokens and mimic the format of PHP's own (pre 5.4) error messages. Example:

  Old: Unexpected token T_STATIC on line 1
  New: Syntax error, unexpected T_STATIC, expecting T_STRING or T_NS_SEPARATOR or '{'
  

• PHPParser_PrettyPrinter_Zend was renamed to PHPParser_PrettyPrinter_Default as the default pretty printer only very loosely applies the Zend Coding Standard. The class PHPParser_PrettyPrinter_Zend extends PHPParser_PrettyPrinter_Default to maintain backwards compatibility.

• The pretty printer now prints namespaces in semicolon-style if possible (i.e. if the file does not contain a global namespace declaration).

• Added prettyPrintFile(array $stmts) method which will pretty print a file of statements including the opening <?php tag if it is required. Use of this method will also eliminate the unnecessary <?php ?> at the start and end of files using inline HTML.

• There now is a builder for interfaces (PHPParser_Builder_Interface).

• An interface for the node traversation has been added: PHPParser_NodeTraverserInterface

• Fix pretty printing of include expressions (precedence information was missing).

• Improve performance of PrettyPrinter construction by no longer using the uniqid() function.
