Version 4.0.4-dev
Nothing yet.
Version 4.0.3 (2018-07-15)
Fixed
- Fixed possible undefined offset notice in formatting-preserving printer. (#513)
Added
- Improved error recovery inside arrays.
- Preserve trailing comment inside classes. Note: This change is possibly BC breaking if your code validates that classes can only contain certain statement types. After this change, classes can also contain Nop statements, while this was not previously possible. (#509)
Version 4.0.2 (2018-06-03)
Added
- Improved error recovery inside classes.
- Support error recovery for
foreachwithoutas. - Support error recovery for parameters without variable (
function (Type ) {}). - Support error recovery for functions without body (
function ($foo)).
Version 4.0.1 (2018-03-25)
Added
- [PHP 7.3] Added support for trailing commas in function calls.
- [PHP 7.3] Added support for by-reference array destructuring.
- Added checks to node traverser to prevent replacing a statement with an expression or vice versa. This should prevent common mistakes in the implementation of node visitors.
- Added the following methods to
BuilderFactory, to simplify creation of expressions:funcCall()methodCall()staticCall()new()constFetch()classConstFetch()
Version 4.0.0 (2018-02-28)
- No significant code changes since the beta 1 release.
Version 4.0.0-beta1 (2018-01-27)
Fixed
- In formatting-preserving pretty printer: Fixed indentation when inserting into lists. (#466)
Added
- In formatting-preserving pretty printer: Improved formatting of elements inserted into multi-line arrays.
Removed
- The
Autoloaderclass has been removed. It is now required to use the Composer autoloader.
Version 4.0.0-alpha3 (2017-12-26)
Fixed
- In the formatting-preserving pretty printer:
- Fixed comment indentation.
- Fixed handling of inline HTML in the fallback case.
- Fixed insertion into list nodes that require creation of a code block.
Added
- Added support for inserting at the start of list nodes in formatting-preserving pretty printer.
Version 4.0.0-alpha2 (2017-11-10)
Added
- In the formatting-preserving pretty printer:
- Added support for changing modifiers.
- Added support for anonymous classes.
- Added support for removing from list nodes.
- Improved support for changing comments.
- Added start token offsets to comments.
Version 4.0.0-alpha1 (2017-10-18)
Added
- Added experimental support for format-preserving pretty-printing. In this mode formatting will be preserved for parts of the code which have not been modified.
- Added
replaceNodesoption toNameResolver, defaulting to true. If this option is disabled, resolved names will be added asresolvedNameattributes, instead of replacing the original names. - Added
NodeFinderclass, which can be used to find nodes based on a callback or class name. This is a utility to avoid custom node visitor implementations for simple search operations. - Added
ClassMethod::isMagic()method. - Added
BuilderFactorymethods:val()method for creating an AST for a simple value,concat()for creating concatenation trees,args()for preparing function arguments. - Added
NameContextclass, which encapsulates theNameResolverlogic independently of the actual AST traversal. This facilitates use in other context, such as class names in doc comments. Additionally it provides an API for getting the shortest representation of a name. - Added
Node::setAttributes()method. - Added
JsonDecoder. This allows conversion JSON back into an AST. - Added
NamemethodstoLowerString()andisSpecialClassName(). - Added
IdentifierandVarLikeIdentifiernodes, which are used in place of simple strings in many places. - Added
getComments(),getStartLine(),getEndLine(),getStartTokenPos(),getEndTokenPos(),getStartFilePos()andgetEndFilePos()methods toNode. These provide a more obvious access point for the already existing attributes of the same name. - Added
ConstExprEvaluatorto evaluate constant expressions to PHP values. - Added
Expr\BinaryOp::getOperatorSigil(), returning+forExpr\BinaryOp\Plus, etc.
Changed
- Many subnodes that previously held simple strings now use
Identifier(orVarLikeIdentifier) nodes. Please see the UPGRADE-4.0 file for an exhaustive list of affected nodes and some notes on possible impact. - Expression statements (
expr;) are now represented using aStmt\Expressionnode. Previously these statements were directly represented as their constituent expression. - The
namesubnode ofParamhas been renamed tovarand now contains aVariablerather than a plain string. - The
namesubnode ofStaticVarhas been renamed tovarand now contains aVariablerather than a plain string. - The
varsubnode ofClosureUsenow contains aVariablerather than a plain string. - The
varsubnode ofCatchnow contains aVariablerather than a plain string. - The
aliassubnode ofUseUseis nownullif no explicit alias is given. As such,use Foo\Baranduse Foo\Bar as Barare now represented differently. ThegetAlias()method can be used to get the effective alias, even if it is not explicitly given.
Removed
- Support for running on PHP 5 and HHVM has been removed. You can however still parse code of old PHP versions (such as PHP 5.2), while running on PHP 7.
- Removed
typesubnode onClass,ClassMethodandPropertynodes. Useflagsinstead. - The
ClassConst::isStatic()method has been removed. Constants cannot have a static modifier. - The
NodeTraverserno longer acceptsfalseas a return value from aleaveNode()method.NodeTraverser::REMOVE_NODEshould be returned instead. - The
Node::setLine()method has been removed. If you really need to, you can usesetAttribute()instead. - The misspelled
Class_::VISIBILITY_MODIFER_MASKconstant has been dropped in favor ofClass_::VISIBILITY_MODIFIER_MASK. - The XML serializer has been removed. As such, the classes
Serializer\XML, andUnserializer\XML, as well as the interfacesSerializerandUnserializerno longer exist. - The
BuilderAbstractclass has been removed. It's functionality is moved intoBuilderHelpers. However, this is an internal class and should not be used directly.

NodeAbstract::getType().
Version 3.1.2 (2017-11-04)
Fixed
- Comments on empty blocks are now preserved on a
Stmt\Nopnode. (#382)
Added
- Added

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
objecttype. This meansobjecttypes will now be represented as a builtin type (a simple"object"string), rather than a className.
Fixed
- Floating-point numbers are now printed correctly if the LC_NUMERIC locale uses a comma as decimal separator.
Changed
Name::$partsis no longer deprecated.
Version 3.0.6 (2017-06-28)
Fixed
- Fixed the spelling of
Class_::VISIBILITY_MODIFIER_MASK. The previous spelling ofClass_::VISIBILITY_MODIFER_MASKis preserved for backwards compatibility. - The pretty printing will now preserve comments inside array literals and function calls by printing the array items / function arguments on separate lines. Array literals and functions that do not contain comments are not affected.
Added
- Added
Builder\Param::makeVariadic().
Deprecated
- The
Node::setLine()method has been deprecated.
Version 3.0.5 (2017-03-05)
Fixed
- Name resolution of
NullableTypes is now performed earlier, so that a fully resolved signature is available when a function is entered. (#360) Errornodes are now considered empty, while previously they extended until the token where the error occurred. This made some nodes larger than expected. (#359)- Fixed notices being thrown during error recovery in some situations. (#362)
Version 3.0.4 (2017-02-10)
Fixed
- Fixed some extensibility issues in pretty printer (
pUseType()is now public andpPrec()calls intop(), instead of directly dispatching to the type-specific printing method). - Fixed notice in
bin/php-parsescript.
Added
- Error recovery from missing semicolons is now supported in more cases.
- Error recovery from trailing commas in positions where PHP does not support them is now supported.
Version 3.0.3 (2017-02-03)
Fixed
- In
"$foo[0]"the0is now parsed as anLNumberrather thanString. (#325) - Ensure integers and floats are always pretty printed preserving semantics, even if the particular value can only be manually constructed.
- Throw a
LogicExceptionwhen trying to pretty-print anErrornode. Previously this resulted in an undefined method exception or fatal error.
Added
- [PHP 7.1] Added support for negative interpolated offsets:
"$foo[-1]" - Added
preserveOriginalNamesoption toNameResolver. If this option is enabled, anoriginalNameattribute, containing the unresolved name, will be added to each resolved name. - Added
php-parse --with-positionsoption, 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 interfacesSerializerandUnserializerare 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 inArrayItem. Now nestedList_nodes are always wrapped inArrayItems. (#321)
Version 3.0.0 (2016-11-30)
Added
- Added support for dumping node positions in the NodeDumper through the
dumpPositionsoption. - 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
ErrorHandlerinterface, andErrorHandler\ThrowingandErrorHandler\Collectingas specific implementations. These provide a general mechanism for handling error recovery. - Added optional
ErrorHandlerargument toParser::parse(),Lexer::startLexing()andNameResolver::__construct(). - The
NameResolvernow adds anamespacedNameattribute on name nodes that cannot be statically resolved (unqualified unaliased function or constant names in namespaces).
Fixed
- Fixed attribute assignment for
GroupUseprefix and variables in interpolated strings.
Changed
- The constants on
NameTraverserInterfacehave been moved into theNameTraverserclass. - Due to the error handling changes, the
Parserinterface andLexerAPI 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 returnsnullfor empty slices, previouslynew Name([])was used.Name::concat()now also supports concatenation withnull.
Removed
- Removed
Name::append()andName::prepend(). These mutable methods have been superseded by the immutableName::concat(). - Removed
Error::getRawLine()andError::setRawLine(). These methods have been superseded byError::getStartLine()andError::setStartLine(). - Removed support for node cloning in the
NodeTraverser. - Removed
$separatorargument fromName::toString(). - Removed
throw_on_errorparser option andParser::getErrors()method. Use theErrorHandlermechanism 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 anodeTypeproperty. - The
InlineHTMLnode now has anhasLeadingNewlineattribute, 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-parsescript through the--with-recoveryor-rflags.
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 Objassignments. - 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
voidanditerabletypes. These will now be represented as strings (instead ofNameinstances) similar to other builtin types. - [7.1] Added support for class constant visibility. The
ClassConstnode now has aflagssubnode holding the visibility modifier, as well asisPublic(),isProtected()andisPrivate()methods. The constructor changed to accept the additional subnode. - [7.1] Added support for nullable types. These are represented using a new
NullableTypenode with a singletypesubnode. - [7.1] Added support for short array destructuring syntax. This means that
Arraynodes may now appear as the left-hand-side of assignments and foreach value targets. Additionally the array items may now containnullvalues if elements are skipped. - [7.1] Added support for keys in list() destructuring. The
Listsubnodevarshas been renamed toitemsand now containsArrayItems instead of plain variables. - [7.1] Added support for multi-catch. The
Catchsubnodetypehas been renamed totypesand is now an array ofNames. Name::slice()now supports lengths and negative offsets. This brings it in line witharray_slice()functionality.
Changed
Due to PHP 7.1 support additions described above, the node structure changed as follows:
voidanditerabletypes are now stored as strings if the PHP 7 parser is used.- The
ClassConstconstructor changed to accept an additionalflagssubnode. - The
Arraysubnodeitemsmay now containnullelements (destructuring). - The
Listsubnodevarshas been renamed toitemsand now containsArrayItems instead of plain variables. - The
Catchsubnodetypehas been renamed totypesand is now an array ofNames.
Additionally the following changes were made:
- The
typesubnode onClass,ClassMethodandPropertyhas been renamed toflags. Thetypesubnode has retained for backwards compatibility and is populated to the same value asflags. However, writes totypewill not updateflags. - The
TryCatchsubnodefinallyStmtshas been replaced with afinallysubnode that holds an explicitFinallynode. This allows for more accurate attribute assignment. - The
Traitconstructor now has the same form as theClassandInterfaceconstructors: It takes an array of subnodes. Unlike classes/interfaces, traits can only have astmtssubnode. - The
NodeDumpernow 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\Standardare now protected. Previously 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()andComment::setText()methods have been removed. - The deprecated
Name::set(),Name::setFirst()andName::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-\x1Finside 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 Objassignments. - 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 uppercaseB) in a number of places. - Fixed reformatting of indented parts in a certain non-standard comment style.
Added
- Added
dumpCommentsoption to node dumper, to enable dumping of comments associated with nodes. - Added
Stmt\Nopnode, 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
kindattribute toExpr\Exitto distinguish betweenexitanddie. - Added
kindattribute toScalar\LNumberto distinguish between decimal, binary, octal and hexadecimal numbers. - Added
kindattribute toExpr\Arrayto distinguish betweenarray()and[]. - Added
kindattribute toScalar\StringandScalar\Encapsedto distinguish between single-quoted, double-quoted, heredoc and nowdoc string. - Added
docLabelattribute toScalar\StringandScalar\Encapsed, if it is a heredoc or nowdoc string. - Added start file offset information to
Commentnodes. - Added
setReturnType()method to function and method builders. - Added
-hand--helpoptions tophp-parsescript.
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
PhpParserfor easier downstream distribution.
Deprecated
- The
Comment::setLine()andComment::setText()methods have been deprecated. Construct new objects instead.
Removed
- The internal (but public) method
Scalar\LNumber::parse()has been removed. A non-internalLNumber::fromString()method has been added instead.
Version 2.0.1 (2016-02-28)
Fixed
declare() {}anddeclare();are not semantically equivalent and will now result in different ASTs. The format case will have an emptystmtsarray, while the latter will setstmtstonull.- Magic constants are now supported as semi-reserved keywords.
- A shebang line like
#!/usr/bin/env phpis 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<?phpif 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\EncapsStringPartnodes. Previously raw strings were used. This affects thepartschild ofScalar\EncapsandExpr\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.phptophp-parseand registered it as a composer bin. - Use composer PSR-4 autoloader instead of custom autoloader.
- Specify phpunit as a dev dependency.
Added
- Added
shortArraySyntaxoption 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.
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\GroupUsenodes. Furthermore atypeattribute was added toStmt\UseUseto 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 beNameinstances there. - Unicode escape sequences.
- Group use declarations. These are represented using
- Added
PhpParser\ParserFactoryclass, 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\Parseris now an interface, implemented byParser\Php5,Parser\Php7andParser\Multiple. TheMultipleparser will try multiple parsers, until one succeeds.- Token constants are now defined on
PhpParser\Parser\Tokensrather thanPhpParser\Parser. - The
Name->set(),Name->append(),Name->prepend()andName->setFirst()methods are deprecated in favor ofName::concat()andName->slice(). - The
NodeTraverserno longer clones nodes by default. The old behavior can be restored by passingtrueto the constructor. - The constructor for
Scalarnodes no longer has a default value. E.g.new LNumber()should now be written asnew LNumber(0).
This changelog only includes changes from the 2.0 series. For older changes see the 1.x series changelog and the 0.9 series changelog.
