PHP 8 Language Feature Support

PHP_CodeSniffer has run under PHP 8 for some time, but it has not supported all new language features until this release. Version 3.6.0 adds support for all new PHP 8 language features, including:

  • Attributes
  • Constructor property promotion
  • Named arguments
  • Union types
  • Match expressions
  • Static and Mixed return types

Note: All standards and sniffs included with PHP_CodeSniffer have been updated to support these language features, but external standards and sniffs may need updating before they are able to detect them correctly.

Changelog

  • Added support for PHP 8.0 union types
    • A new T_TYPE_UNION token is available to represent the pipe character
    • File::getMethodParameters(), getMethodProperties(), and getMemberProperties() will now return union types
    • Thanks to Juliette Reinders Folmer for the patch

    • The PHP-supplied T_ATTRIBUTE token marks the start of an attribute
    • A new T_ATTRIBUTE_END token is available to mark the end of an attribute
    • New attribute_owner and attribute_closer indexes are available in the tokens array for all tokens inside an attribute
    • Tokenizing of attributes has been backfilled for older PHP versions
    • The following sniffs have been updated to support attributes:
      • PEAR.Commenting.ClassComment
      • PEAR.Commenting.FileComment
      • PSR1.Files.SideEffects
      • PSR12.Files.FileHeader
      • Squiz.Commenting.ClassComment

    • Thanks to Juliette Reinders Folmer for the patch
  • Added support for PHP 8.0 match expressions
    • Match expressions are now tokenised with parenthesis and scope openers and closers
      • Sniffs can listen for the T_MATCH token to process match expressions
      • Note that the case and default statements inside match expressions do not have scopes set
    • A new T_MATCH_ARROW token is available to represent the arrows in match expressions
    • A new T_MATCH_DEFAULT token is available to represent the default keyword in match expressions
    • All tokenizing of match expressions has been backfilled for older PHP versions
    • The following sniffs have been updated to support match expressions:
      • Generic.CodeAnalysis.AssignmentInCondition
      • Generic.CodeAnalysis.EmptyPHPStatement
        • Thanks to Vadim Borodavko for the patch
      • Generic.CodeAnalysis.EmptyStatement
      • Generic.PHP.LowerCaseKeyword
      • PEAR.ControlStructures.ControlSignature
      • PSR12.ControlStructures.BooleanOperatorPlacement
      • Squiz.Commenting.LongConditionClosingComment

    • Thanks to Juliette Reinders Folmer for the patch
  • The value of the T_FN_ARROW token has changed from "T_FN_ARROW" to "PHPCS_T_FN_ARROW" to avoid package conflicts
    • This will have no impact on custom sniffs unless they are specifically looking at the value of the T_FN_ARROW constant
    • If sniffs are just using constant to find arrow functions, they will continue to work without modification
    • Thanks to Juliette Reinders Folmer for the patch
  • File::findStartOfStatement() now works correctly when passed the last token in a statement
  • File::getMethodParameters() now supports PHP 8.0 constructor property promotion
    • Returned method params now include a property_visibility and visibility_token index if property promotion is detected
    • Thanks to Juliette Reinders Folmer for the patch
  • File::getMethodProperties() now includes a return_type_end_token index in the return value
    • This indicates the last token in the return type, which is helpful when checking union types
    • Thanks to Juliette Reinders Folmer for the patch
  • Include patterns are now ignored when processing STDIN
    • Previously, checks using include patterns were excluded when processing STDIN when no file path was provided via --stdin-path
    • Now, all include and exclude rules are ignored when no file path is provided, allowing all checks to run
    • If you want include and exclude rules enforced when checking STDIN, use --stdin-path to set the file path
    • Thanks to Juliette Reinders Folmer for the patch
  • Spaces are now correctly escaped in the paths to external on Windows
    • Thanks to Juliette Reinders Folmer for the patch
  • Added Generic.NamingConventions.AbstractClassNamePrefix to enforce that class names are prefixed with "Abstract"
    • Thanks to Anna Borzenko for the contribution
  • Added Generic.NamingConventions.InterfaceNameSuffix to enforce that interface names are suffixed with "Interface"
    • Thanks to Anna Borzenko for the contribution
  • Added Generic.NamingConventions.TraitNameSuffix to enforce that trait names are suffixed with "Trait"
    • Thanks to Anna Borzenko for the contribution
  • Generic.CodeAnalysis.UnusedFunctionParameter can now be configured to ignore variable usage for specific type hints
    • This allows you to suppress warnings for some variables that are not required, but leave warnings for others
    • Set the ignoreTypeHints array property to a list of type hints to ignore
    • Thanks to Petr Bugyík for the patch
  • Generic.Formatting.MultipleStatementAlignment can now align statements at the start of the assignment token
    • Previously, the sniff enforced that the values were aligned, even if this meant the assignment tokens were not
    • Now, the sniff can enforce that the assignment tokens are aligned, even if this means the values are not
    • Set the alignAtEnd sniff property to false to align the assignment tokens
    • The default remains at true, so the assigned values are aligned
    • Thanks to John P. Bloch for the patch
  • Generic.PHP.LowerCaseType now supports checking of typed properties
    • Thanks to Juliette Reinders Folmer for the patch
  • Generic.PHP.LowerCaseType now supports checking of union types
    • Thanks to Juliette Reinders Folmer for the patch
  • PEAR.Commenting.FunctionComment and Squiz.Commenting.FunctionComment sniffs can now ignore private and protected methods
    • Set the minimumVisibility sniff property to protected to ignore private methods
    • Set the minimumVisibility sniff property to public to ignore both private and protected methods
    • The default remains at private, so all methods are checked
    • Thanks to Vincent Langlet for the patch
  • PEAR.Commenting.FunctionComment and Squiz.Commenting.FunctionComment sniffs can now ignore return tags in any method
    • Previously, only __construct and __destruct were ignored
    • Set the list of method names to ignore in the specialMethods sniff property
    • The default remains at __construct and __destruct only
    • Thanks to Vincent Langlet for the patch
  • PSR2.ControlStructures.SwitchDeclaration now supports nested switch statements where every branch terminates
    • Previously, if a CASE only contained a SWITCH and no direct terminating statement, a fall-through error was displayed
    • Now, the error is suppressed if every branch of the SWITCH has a terminating statement
    • Thanks to Vincent Langlet for the patch
  • The PSR2.Methods.FunctionCallSignature.SpaceBeforeCloseBracket error message is now reported on the closing parenthesis token
    • Previously, the error was being reported on the function keyword, leading to confusing line numbers in the error report
  • Squiz.Commenting.FunctionComment is now able to ignore function comments that are only inheritdoc statements
    • Set the skipIfInheritdoc sniff property to true to skip checking function comments if the content is only {@inhertidoc}
    • The default remains at false, so these comments will continue to report errors
    • Thanks to Jess Myrbo for the patch
  • Squiz.Commenting.FunctionComment now supports the PHP 8 mixed type
    • Thanks to Vadim Borodavko for the patch
  • Squiz.PHP.NonExecutableCode now has improved handling of syntax errors
