Utils

• New PHPCSUtils\Utils\AttributeBlock class: Utility functions to examine attribute blocks. #720, #729
  For the purposes of these utilities, an "attribute block" is defined as being an attribute opener, an attribute closer and everything between. I.e. #[MyAttribute(1, 2), AnotherAttribute] is one attribute block.
  Initial set of available methods:
  • getAttributes() to retrieve information about each attribute being instantiated within a particular attribute block.
  • countAttributes() to retrieve a count of the number of attribute instantiations with a particular attribute block.
  • appliesTo() to find the stack pointer to the language construct an attribute block applies to.
• New PHPCSUtils\Utils\Constants::getAttributeOpeners(), PHPCSUtils\Utils\FunctionDeclarations::getAttributeOpeners(), PHPCSUtils\Utils\ObjectDeclarations::getAttributeOpeners() and PHPCSUtils\Utils\Variables::getAttributeOpeners() utility methods. #719
  These methods will each return an array with the stack pointers to the attribute openers for applicable attribute blocks.
  This may be an empty array if no attributes apply to the constant/function/OO structure/property.

Compatibility with the new PHP_CodeSniffer 4.x branch in anticipation of the PHP_CodeSniffer 4.0 release. #674, #679
PHPCSUtils should now be fully compatible with PHP_CodeSniffer 4.0 (again). If you still find an issue, please report it.

PHPCS BackCompat

• BCFile::findExtendedClassName(): sync with PHPCS 4.0.0 - support for namespace relative names when used as the extended parent class name. #674
• BCFile::findImplementedInterfaceNames(): sync with PHPCS 4.0.0 - support for namespace relative names when used in implemented interface names. #674
• BCFile::getMemberProperties(): sync with PHPCS 3.12.0 - support for PHP 8.4 final properties. Thanks @DanielEScherzer! #646
• BCFile::getMemberProperties(): sync with PHPCS 3.13.1 - support for PHP 8.4 asymmetric visibility. #677
• BCFile::getMemberProperties(): sync with PHPCS 4.0.0. #674
  • Add support for PHP 8.4 properties in interfaces.
  • Removed parse error warning.
• BCFile::getMethodParameters(): sync with PHPCS 3.13.1 - support for PHP 8.4 asymmetric visibility. #677
• BCFile::findStartOfStatement(): sync with PHPCS 3.12.1 - support for goto as a switch - case terminating statement. #661
• BCTokens::nameTokens() as introduced in PHPCS 4.0.0. #674
  The same token array previously already existed in PHPCSUtils as Collections::nameTokens().
• BCTokens::functionNameTokens(): sync with PHPCS 4.0.0 - added the T_ANON_CLASS token. #674
• BCTokens::parenthesisOpeners(): sync with PHPCS 4.0.0 - added the T_USE, T_ISSET, T_UNSET, T_EMPTY, T_EVAL and T_EXIT tokens. #674
  Note: While T_USE, T_ISSET, T_UNSET, T_EMPTY, T_EVAL and T_EXIT will be included in the return value for this method,
  the associated parentheses will not have the 'parenthesis_owner' index set unless PHPCS 4.0.0 is used.
  Use the Parentheses::getOwner() or the Parentheses::hasOwner() methods if you need to check
  whether any of these tokens are a parentheses owner. The methods in the Parentheses class are PHPCS cross-version compatible.

TestUtils

• New PHPCSUtils\TestUtils\ConfigDouble class as a lightweight and more stable alternative to directly using the PHPCS native Config class in tests. #550, #612
  Props to @fredden for helping me find and fix a bug in this feature before it was released.
• New PHPCSUtils\TestUtils\RulesetDouble class which allows for creating a Ruleset object without registering any sniffs. #674
  This allows for the PHPCSUtils\TestUtils\UtilityMethodTestCase class to be cross-version compatible with both PHP_CodeSniffer 3.x as well as 4.x.
• New PHPCSUtils\TestUtils\UtilityMethodTestCase::parseFile() method to allow for on-demand tokenizing of a (secondary) test case file. #591, #610
  This method is intended for tests which need to use multiple test case files, like, for example, tests which need to verify that a utility resets a $fileName property on seeing another file.
• New PHPCSUtils\TestUtils\UtilityMethodTestCase::testTestMarkersAreUnique() and PHPCSUtils\TestUtils\UtilityMethodTestCase::assertTestMarkersAreUnique() methods which automatically check that code sample files used with this TestCase do not contain duplicate test case markers. #642
  If needs be, the test method can be disabled by overloading it (discouraged). If a test uses multiple test case/code sample files, the assertion method can be called directly.

Tokens

• New Collections::constantTypeTokens() method to support PHP 8.3 typed class constants. #562
• New Collections::ternaryOperators() method. #549
• T_EXIT to the Collections::functionCallTokens() and Collections::parameterPassingTokens() in light of the PHP 8.4 "exit as function" change. #618
• The PHP 8.4 asymmetric visibility tokens have been added to the Collections::propertyModifierKeywords() method. #653
• T_INTERFACE has been added to the Collections::ooPropertyScopes() method for PHP 8.4 interface properties support. #674

Utils

• New PHPCSUtils\Utils\Constants class: Utility functions to examine (class) constants. #562
  Initially available method: getProperties() to retrieve an array of information about an OO constant declaration.
• New PHPCSUtils\Utils\FileInfo class: Utility functions to check characteristics of the file under scan. #572
  Initial set of available methods: hasByteOrderMark() and hasSheBang().
• New PHPCSUtils\Utils\FilePath class: Utility functions for handling and comparing file paths. #593
  Initial set of available methods: getName() to retrieve the normalized path for the current file, isStdin(), normalizeAbsolutePath(), normalizeDirectorySeparators(), trailingSlashIt() and startsWith().
• New PHPCSUtils\Utils\TypeString class: Utility functions for analysing typestrings as retrieved via the various available getParameters()/getProperties() methods. #588
  Initial set of available methods: getKeywordTypes(), isKeyword(), normalizeCase(), isSingular(), isNullable(), isUnion(), isIntersection(), isDNF(), toArray(), toArrayUnique(), filterKeywordTypes() and filterOOTypes().
  Note: The is*() methods will not check if the type string provided is valid, as doing so would inhibit what sniffs can flag. The is*() methods will only look at the form of the type string to determine if it could be valid for a certain type.
• New PHPCSUtils\Utils\ObjectDeclarations::getDeclaredConstants(), PHPCSUtils\Utils\ObjectDeclarations::getDeclaredEnumCases(), PHPCSUtils\Utils\ObjectDeclarations::getDeclaredProperties() and PHPCSUtils\Utils\ObjectDeclarations::getDeclaredMethods() utility methods. #592
  These methods will each return an array with the name of the constant/case/property/method as the key and the typical stack pointer needed for further processing.
  The retrieval of this information is highly optimized for performance. If a sniff needs to search for a named constant/enum case/property/method in an OO structure, in most cases, these methods should be the recommended way for finding the declaration, instead of the sniff attempting to do this itself.
  Mind: the return value of the getDeclaredProperties() method includes constructor promoted properties. Passing the stack pointer of constructor promoted properties onto a call to the Variables::getMemberProperties() method, however, is currently not supported.

• The exceptions thrown by PHPCSUtils native utilities have been made more modular and more specific. #598, #599, #600
  • Passing a parameter of the wrong type will now result in a PHPCSUtils\Exceptions\TypeError being thrown.
  • Passing a parameter of the correct type, but with an invalid value, like an empty string when only non-empty strings are expected/accepted, will now result in a PHPCSUtils\Exceptions\ValueError being thrown.
  • Passing a (positive) integer stack pointer, which doesn't exist in the token stack of the current file, will now result in a PHPCSUtils\Exceptions\OutOfBoundsStackPtr being thrown.
  • Passing a stack pointer to a token which is not within the range of token types which is accepted by the method, will now result in a PHPCSUtils\Exceptions\UnexpectedTokenType being thrown.
  • Logic errors will now result in a PHPCSUtils\Exceptions\LogicException being thrown.
    This can occur, for instance, when a method takes a $start and $end parameter and the $end pointer is before the $start pointer.
  • Missing, conditionally required, parameters, will now result in a PHPCSUtils\Exceptions\MissingArgumentError being thrown.
  • Generic errors will now result in a PHPCSUtils\Exceptions\RuntimeException being thrown.
  • Previously the PHPCS native PHP_CodeSniffer\Exceptions\RuntimeException was used for all these exceptions.
    Catching the PHPCS native RuntimeException will still catch the new exceptions, but it is strongly recommended to be more selective when catching exceptions to prevent accidentally hiding errors in sniffs.
  • Also note that the PHPCSUtils native utilities now include more and stricter type checking to help surface bugs in sniffs.

Abstract Sniffs

• The AbstractArrayDeclarationSniff::process() method will no longer hide exceptions about a non-integer or non-existent stack pointer being passed. #600
• The AbstractArrayDeclarationSniff::processArray() method will no longer hide exceptions about non-integer or non-existent stack pointers being passed. #600

  Passing these will now result in an exception.
• BCFile::getDeclarationName(): sync with PHPCS 4.0.0 - the method will now always return a string. #674
  Previously, the method could return null when the name could not be determined. Now it will return an empty string.

• All methods in the PassedParameters class will now be able to analyze exit/die when used as a function call. #618
• The Scopes::isOOProperty() method now allows for PHP 8.4 properties in interfaces. #674
  • This also adds support for properties in interfaces to the Variables::getMemberProperties() method.
• The UseStatements::splitAndMergeImportUseStatement() method will no longer hide exceptions about a non-integer, non-existent or non-T_USE stack pointer being passed. #600

Removed

Everything which was previously deprecated in the 1.0.0-alpha4 release, has now been removed. #410

This includes:

• The PHPCS23Utils standard.
• [Collections] class: direct access to the properties in the class.
• [Collections] class: the Collections::arrowFunctionTokensBC(), Collections::functionDeclarationTokensBC(), Collections::parameterTypeTokensBC(), Collections::propertyTypeTokensBC() and Collections::returnTypeTokensBC() methods.
• The ControlStructures::getDeclareScopeOpenClose() method.
• The FunctionDeclarations::getArrowFunctionOpenClose() method.

Notes:

• While still in alpha, some BC-breaks may be introduced. These are clearly indicated in the changelog with the :warning: symbol.
• Until PHPCS 4.x has been released, PHPCSUtils does not formally support it, though an effort is made to keep up with the changes and anticipate potential compatibility issues. For testing purposes only, the composer configuration allows for PHPCSUtils to be installed with PHPCS 4.x.

Breaking Changes

Support for PHP_CodeSniffer < 3.7.1 has been dropped after consultation with the principle external standards which depend on PHPCSUtils. #347

This was unfortunately necessary as the incessant additions of new syntaxes since PHP 7.4 made it impossible to continue to support PHPCS < 3.7.1, while still providing reliable results for modern PHP code.

Added

Now support for PHPCS < 3.7.1 has been dropped, this edition adds support to all functionality in PHPCSUtils for new syntaxes and features from PHP 8.0 and 8.1 and preliminary support for PHP 8.2.

This means that support for the following syntaxes/features has been added (or existing support verified/improved):

• PHP 7.4
  • Array unpacking in array expressions.
• PHP 8.0
  • The mixed type. #163
  • Union types, including supporting the false and null types. #168, #225
  • Constructor property promotion. #169, #226
  • Nullsafe object operators. #176, #183
  • Namespaced names as single token (cross-version PHPCS 3.x vs 4.x). #205, #206, #207, #208, #209, #210, #211, #212, #213, #217, #241
  • Dereferencing of interpolated text strings.
  • Named arguments in function calls. #235, #243, #383
  • Match expressions. #247, #335, #356
  • Trailing commas in parameter lists and closure use lists.
  • Attributes. #357
• PHP 8.1
  • Enumerations. #285, #358
  • Explicit octal notation. #293
  • Array unpacking with string keys.
  • never type.
  • Named parameters after argument unpacking. #383
  • First class callables. #362
  • Readonly properties. #363
  • new in initializers.
  • Intersection types. #365
• PHP 8.2
  • Constants in traits. #366
  • Readonly classes. #367
  • true type. #368
  • null and false as stand-alone types.

Please report any bugs/oversights you encounter!

PHPCS Backcompat

• BCTokens::magicConstants() as introduced in PHPCS 3.5.6. #172 The same token array previously already existed in PHPCSUtils as Collections::$magicConstants (which has now been deprecated).

TestUtils

• New UtilityMethodTestCase::usesPhp8NameTokens() method as a helper for tests using token position calculations when testing against both PHPCS 3.x as well as 4.x. #200, #217, #241

Tokens

• New [PHPCSUtils\Tokens\TokenHelper][TokenHelper] class: Utility functions for working with tokens and token collections. #304 This class initially contains a tokenExists() method to work around potential interference from PHP-Parser also backfilling tokens. :point_right: External standards using a function call to defined() to determine whether a token is available should replace those with a function call to the TokenHelper::tokenExists() method.
• New [Collections::arrayOpenTokensBC()][Collections] method. #233, #311
• New [Collections::functionCallTokens()][Collections] method to retrieve the tokens which can represent function calls and function-call-like language constructs, like class instantiations. #233
• New [Collections::nameTokens()][Collections] method to retrieve the tokens which can be used for "names", be it namespace, OO, function or constant names. #204, #217
• New [Collections::namespacedNameTokens()][Collections] method to retrieve the tokens which can be encountered in a fully, partially or unqualified name and in namespace relative names. #202, #217
• New [Collections::parameterPassingTokens()][Collections] method to retrieve the tokens which can be passed to the methods in the [PassedParameters] class. #233
• New [Collections::phpOpenTags()][Collections] method. #254
• New [Collections::shortArrayListOpenTokensBC()][Collections] method. #381

Utils

• New [PHPCSUtils\Utils\Context][Context] class: Utility functions to determine the context in which an arbitrary token is used. #219. #390 Initial set of available methods: inEmpty(), inIsset(), inUnset(), inAttribute, inForeachCondition() and inForCondition().
• New [PHPCSUtils\Utils\MessageHelper][MessageHelper] class: Utility functions for creating error/warning messages. #249, #391 Initial set of available methods: addMessage(), addFixableMessage(), stringToErrorcode() and showEscapeChars().
• New PHPCSUtils\Utils\PassedParameters::getParameterFromStack() efficiency method to retrieve a potentially named function call parameter from a parameter information stack as previously retrieved via PassedParameters::getParameters(). #235, #237, #383
• New PHPCSUtils\Utils\TextStrings::getEndOfCompleteTextString() method. #320 This method allows to retrieve the stack pointer to the last token within a - potentially multi-line - text string. This method compliments the TextStrings::getCompleteTextString() method which will retrieve the contents of the complete text string.
• New PHPCSUtils\Utils\TextStrings::getEmbeds() method to retrieve an array with all variables/expressions as embedded in a text string. #321
• New PHPCSUtils\Utils\TextStrings::stripEmbeds() method to strip all embedded variables/expressions from a text string. #321
• New PHPCSUtils\Utils\TextStrings::getStripEmbeds() method. #321 This method is public for those rare cases where both the embeds, as well as the text stripped off embeds, is needed.
• New PHPCSUtils\Utils\UseStatements::mergeImportUseStatements() method. #196

Other

• PHPCSUtils will now cache the results of (potentially) token walking intensive or processing intensive function calls during a run. #332, #377 This should significantly improve performance when multiple sniffs call these functions for the same token during a PHPCS run. The results of the following functions will now be cached:
  • Arrays::getDoubleArrowPtr()
  • Arrays::isShortArray()
  • FunctionDeclarations::getParameters()
  • Lists::getAssignments()
  • Lists::isShortList()
  • Namespaces::findNamespacePtr()
  • PassedParameters::getParameters()
  • TextStrings::getEndOfCompleteTextString()
  • TextStrings::getStripEmbeds()
  • UseStatements::splitImportUseStatement()

Changed

PHPCS Backcompat

• All token array methods in the [BCTokens] class are fully up-to-date with the upstream PHP_CodeSniffer\Util\Tokens properties as per PHPCS master at the time of this release. #327, #347, #360
• All methods in the [BCFile] class are fully up-to-date with the upstream PHP_CodeSniffer\Files\File methods as per PHPCS master at the time of this release. #347
• BCFile::getMethodParameters(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #251
• If a non-existent token array is requested from the BCTokens class, a PHPCSUtils\Exceptions\InvalidTokenArray exception will be thrown. #344 The PHPCSUtils\Exceptions\InvalidTokenArray exception extends the PHPCS native PHP_CodeSniffer\Exceptions\RuntimeException. Previously, an empty array would be returned.

TestUtils

• UtilityMethodTestCase: all properties contained in the test case class will now always be reset after the tests have run. #325
• UtilityMethodTestCase::getTargetToken(): when the target token cannot be found, the method will now throw a (catchable) PHPCSUtils\Exceptions\TestTargetNotFound exception instead of failing the test. #248, #371 If uncaught, this means that the test will be marked as errored instead of failed.
• UtilityMethodTestCase::getTargetToken(): this method is now static, which allows for it to be used in "set up before class" fixtures. #382. #385

Tokens

• Collections::functionCallTokens() and Collections::parameterPassingTokens(): now include the T_PARENT token. #328 This accounts for a change in PHPCS 3.7.0 for how parent in new parent is tokenized.
• If a non-existent token array is requested from the Collections class, a PHPCSUtils\Exceptions\InvalidTokenArray exception will be thrown. #349 The PHPCSUtils\Exceptions\InvalidTokenArray exception extends the PHPCS native PHP_CodeSniffer\Exceptions\RuntimeException.

Utils

• Arrays::isShortArray()/Lists::isShortList(): the underlying logic has been completely refactored for improved accuracy and improved performance. #392
• FunctionDeclarations::getParameters(): the return array of the method may contain two new keys - property_visibility and visibility_token. #169 These keys will only be included if constructor property promotion is detected.
• FunctionDeclarations::getParameters(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #251
• [GetTokensAsString]: previously the tabReplaced() method was an alias for the normal() method. This has now been reversed. #297
• Operators::isReference(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #195
• [Parentheses]: all methods will now recognize isset(), unset(), empty(), exit(), die() and eval() as parentheses owners. #215 Note: PHPCS natively does not recognize these constructs as parentheses owners, though this may change in the future. See: PHPCS#3118
• [PassedParameters]: all methods will now recognize anonymous class instantiations as constructs which can pass parameters. #234
• PassedParameters::getParameters(): when a named parameter is encountered in a function call, the returned parameter information array for that parameter will now contain the following additional keys: 'name', 'name_token' and the top-level index for the parameter will be set to the parameter 'name' instead of its position. #235, #243, #383 The existing 'start', 'end', 'raw' and 'clean' keys will contain the same content as before: the information about the parameter value (excluding the name part).
• PassedParameters::getParameters(): new, optional parameter $limit to allow for limiting the number of parameters/array items to be parsed. #261 This allows for higher efficiency when retrieving the parameters/array entries, especially for large arrays if only the first few entries need to be examined. Use with care on function calls, as this can break support for named parameters!
• PassedParameters::getParameters(): new, optional parameter $isShortArray to allow for skipping the "is short array" check for predetermined short arrays. #269, #270 Use judiciously and with extreme care!
• PassedParameters::getParameter(): new semi-optional $paramNames parameter to allow for retrieving a parameter from a function call using named parameters. #235 :warning: This parameter is required when examining a function call and an exception will be thrown if it was not passed. This new $paramNames parameter allows for passing either the parameter name as a string or as an array of strings. While a parameter can only have one name, a lot of packages have been, and may still be, reviewing and renaming parameters to more descriptive names to support named parameters in PHP 8.0, so, to allow for supporting multiple versions of packages, different names can be used for the same parameter in a PHP 8.0+ function call and by allowing multiple names to be passed, the method supports this.
• PassedParameters::getParameter(): efficiency improvement applicable to function calls not using named parameters and arrays. #261, #262
• PassedParameters::hasParameters(): now allows for the T_PARENT token for new parent() class instantiations. #328 This accounts for a change in PHPCS 3.7.0 regarding how parent in new parent is tokenized.
• PassedParameters::hasParameters(): new, optional parameter $isShortArray to allow for skipping the "is short array" check for predetermined short arrays. #269, #270 Use judiciously and with extreme care!
• UseStatements::getType(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #251

Other

• The master branch has been renamed to stable. #397
• :warning: All non-abstract classes in this package are now final. #376
• The parameter names in various function declarations have been changed to not intersect with reserved keywords. #256 :warning: In the unlikely event an external standard using PHPCSUtils would be using function calls with named parameters, the parameter names will need to be updated to match.
• Composer: The package will now identify itself as a static analysis tool. Thanks [@GaryJones]! #341
• Readme/website homepage: the installation instructions have been updated to include information on installing this library and the included [Composer PHPCS plugin] in combination with Composer >= 2.2. #291, #292
• Various documentation improvements. #216, #309, #394, #395, #396, #398
• Various housekeeping and CI maintenance. Amongst other things, CI is now run via GitHub Actions (#239), the PHPCSUtils native tests now use the PHPUnit Polyfills package (#277) and the tests are now run against PHP 5.4 - 8.2.

Deprecated

:warning: Everything which has currently been deprecated, will be removed before the final 1.0.0 version of PHPCSUtils is tagged.

Tokens

[Collections] class: direct access to the properties in the class is now deprecated for forward-compatibility reasons. All properties have a replacement which should be used instead, in most cases this will be a method with the same name as the previously used property,

Additionally, the following methods in the Collections class have been deprecated:

Utils

• ControlStructures::getDeclareScopeOpenClose(): this method is no longer needed, check the scope_opener/scope_closer on the T_DECLARE token instead. #347
• FunctionDeclarations::getArrowFunctionOpenClose(): this method is no longer needed, check the scope_opener/scope_closer etc on the T_FN token instead. #347
• FunctionDeclarations::isArrowFunction(): this method is no longer needed, use the T_FN token instead. #347

Other

• The PHPCS23Utils standard, which is no longer needed now support for PHPCS < 3.7.1 has been dropped. #347

Removed

• Support for PHPCS < 3.7.1. #347

Utils

• The following constants, which were only intended for internal use, have been removed: #347
  • PHPCSUtils\Utils\Numbers::REGEX_NUMLIT_STRING
  • PHPCSUtils\Utils\Numbers::REGEX_HEX_NUMLIT_STRING
  • PHPCSUtils\Utils\Numbers::UNSUPPORTED_PHPCS_VERSION

Fixed

Abstract Sniffs

• AbstractArrayDeclarationSniff::getActualArrayKey(): will now handle escaped vars in heredoc array keys better. #379

Fixers

• [SpacesFixer]: in a specific new line vs trailing comment situation, the fixer would incorrectly add a stray new line. #229

TestUtils

• UtilityMethodTestCase::getTargetToken(): will now throw a PHPCSUtils\Exceptions\TestMarkerNotFound exception if the provided test marker comment is not found. #273, #372 This prevents the method potentially misidentifying the target token.

Tokens

• Collections::parameterTypeTokens(), Collections::propertyTypeTokens() and Collections::returnTypeTokens(): include the namespace keyword for namespace relative identifier names. #180

Utils

• Arrays::isShortArray()/Lists::isShortList(): fixed a number of bugs which previously resulted in an incorrect short list/short array determination. #392
• FunctionDeclarations::getParameters(): will now correctly recognize namespace relative names when used in a parameter type. #180
• FunctionDeclarations::getProperties(): will now correctly recognize namespace relative names when used in the return type. #180
• ObjectDeclarations::findExtendedClassName(): will now correctly recognize namespace relative names when used as the extended parent class name. #181
• ObjectDeclarations::findExtendedInterfaceNames(): will now correctly recognize namespace relative names when used in extended interface names. #181
• ObjectDeclarations::findImplementedInterfaceNames(): will now correctly recognize namespace relative names when used in implemented interface names. #181
• ObjectDeclarations::getClassProperties(): will now correctly handle classes declared with both the final as well as the abstract keyword. #252
• Operators::isReference(): if one parameter in a function declaration was passed by reference, then all T_BITWISE_AND (not intersection type &'s) tokens would be regarded as references. #188
• Operators::isReference(): the & would not be recognized as a reference for arrow function parameters passed by reference. #192
• Operators::isUnaryPlusMinus(): a preceding exit, break, continue or arrow function => is now recognized as an indicator that a plus/minus sign is unary. #187, #197
• Variables::getMemberProperties(): will now correctly recognize namespace relative names when used in a property type. #180

Notes:

• While still in alpha, some BC-breaks may be introduced. These are clearly indicated in the changelog with the :warning: symbol.
• Until PHPCS 4.x has been released, PHPCSUtils does not formally support it, though an effort is made to keep up with the changes and anticipate potential compatibility issues. For testing purposes, the composer configuration allows for PHPCSUtils to be installed with PHPCS 4.x.
• Until PHP 8.0 has been released, PHPCSUtils does not formally support it, though an effort is made to keep up with the changes and anticipate potential compatibility issues. For testing purposes, the composer configuration allows for PHPCSUtils to be installed with PHP 8.

Fixed

Abstract Sniffs

• AbstractArrayDeclarationSniff: improved parse error handling. #99

PHPCS BackCompat

• BCFile::findEndOfStatement(): now supports arrow functions when used as a function argument, in line with the same change made in PHPCS 3.5.5. #143
• BcFile::isReference(): bug fix, the reference operator was not recognized as such for closures declared to return by reference. #160, PHPCS#2977

Utils

• FunctionDeclarations::getArrowFunctionOpenClose(): now supports arrow functions when used as a function argument, in line with the same change made in PHPCS 3.5.5. #143

• Namespaces::getType(): improved type detection for when the namespace keyword is used as an operator in the global namespace. #132
• TextStrings::getCompleteTextString(): will now remove the newline at the end of a heredoc/nowdoc. #136 PHP itself does not include the last new line in a heredoc/nowdoc text string when handling it, so the method shouldn't either.

Note:

• While still in alpha, some BC-breaks may be introduced. These are clearly indicated in the changelog with the :warning: symbol.

Initial alpha release containing:

• A PHPCS23Utils standard which can be used to allow an external PHPCS standard to be compatible with both PHPCS 2.x as well as 3.x.
• A PHPCSUtils standard which contains generic utilities which can be used when writing sniffs. This standard does not contain any sniffs! To use these utilities in PHPCS 3.x, all that is needed is for this package to be installed and registered with PHPCS using installed_paths. If the package is requested via Composer, this will automatically be handled by the Composer PHPCS plugin. To use these utilities in PHPCS 2.x, make sure the external standard includes the PHPCS23Utils standard in the ruleset.xml file like so: <rule ref="PHPCS23Utils"/>.

All utilities offered are compatible with PHP_CodeSniffer 2.6.0 up to the latest stable release.

This initial alpha release contains the following utility classes:

Abstract Sniffs

• AbstractArrayDeclarationSniff: to examine array declarations.

BackCompat

• BCFile: Backport of the latest versions of PHPCS native utility functions from the PHP_CodeSniffer\Files\File class to make them available in older PHPCS versions without the bugs and other quirks that the older versions of the native functions had.
• BCTokens: Backport of the latest versions of PHPCS native token arrays from the PHP_CodeSniffer\Util\Tokens class to make them available in older PHPCS versions.
• Helper: Utility methods to retrieve (configuration) information from PHP_CodeSniffer 2.x as well as 3.x.

Fixers

• SpacesFixer: Utility to check and, if necessary, fix the whitespace between two tokens.

TestUtils

• UtilityMethodTestCase: Base class for use when testing utility methods for PHP_CodeSniffer. Compatible with both PHPCS 2.x as well as 3.x. Supports PHPUnit 4.x up to 8.x. See the usage instructions in the class docblock.

Tokens

• Collections: Collections of related tokens as often used and needed for sniffs. These are additional "token groups" to compliment the ones available through the PHPCS native PHP_CodeSniffer\Util\Tokens class.
