3.5.3

• The PHP 7.4 T_FN token has been made available for older versions
  • T_FN represents the fn string used for arrow functions
  • The double arrow becomes the scope opener, and uses a new T_FN_ARROW token type
  • The token after the statement (normally a semicolon) becomes the scope closer
  • The token is also associated with the opening and closing parenthesis of the statement
  • Any functions named fn will have a T_FN token for the function name, but have no scope information
  • Thanks to Michał Bundyra for the help with this change
• PHP 7.4 numeric separators are now tokenized in the same way when using older PHP versions
  • Previously, a number like 1_000 would tokenize as T_LNUMBER (1), T_STRING (_000)
  • Now, the number tokenizes as T_LNUMBER (1_000)
  • Sniff developers should consider how numbers with underscores impact their custom sniffs
• The PHPCS file cache now takes file permissions into account
  • The cache is now invalidated for a file when its permissions are changed
• File::getMethodParameters() now supports arrow functions
• File::getMethodProperties() now supports arrow functions
• Added Fixer::changeCodeBlockIndent() to change the indent of a code block while auto-fixing
  • Can be used to either increase or decrease the indent
  • Useful when moving the start position of something like a closure, where you want the content to also move
• Added Generic.Files.ExecutableFile sniff
  • Ensures that files are not executable
  • Thanks to Matthew Peveler for the contribution
• Generic.CodeAnalysis.EmptyPhpStatement now reports unnecessary semicolons after control structure closing braces
  • Thanks to Vincent Langlet for the patch
• Generic.PHP.LowerCaseKeyword now enforces that the fn keyword is lowercase
  • Thanks to Michał Bundyra for the patch
• Generic.WhiteSpace.ScopeIndent now supports static arrow functions
• PEAR.Functions.FunctionCallSignature now adjusts the indent of function argument contents during auto-fixing
  • Previously, only the first line of an argument was changed, leading to inconsistent indents
  • This change also applies to PSR2.Methods.FunctionCallSignature
• PSR2.ControlStructures.ControlStructureSpacing now checks whitespace before the closing parenthesis of multi-line control structures
  • Previously, it incorrectly applied the whitespace check for single-line definitions only
• PSR12.Functions.ReturnTypeDeclaration now checks the return type of arrow functions
  • Thanks to Michał Bundyra for the patch
• PSR12.Traits.UseDeclaration now ensures all trait import statements are grouped together
  • Previously, the trait import section of the class ended when the first non-import statement was found
  • Checking now continues throughout the class to ensure all statements are grouped together
  • This also ensures that empty lines are not requested after an import statement that isn't the last one
• Squiz.Functions.LowercaseFunctionKeywords now enforces that the fn keyword is lowercase
  • Thanks to Michał Bundyra for the patch
• Fixed bug #2586 : Generic.WhiteSpace.ScopeIndent false positives when indenting open tags at a non tab-stop
• Fixed bug #2638 : Squiz.CSS.DuplicateClassDefinitionSniff sees comments as part of the class name
  • Thanks to Raphael Horber for the patch
• Fixed bug #2640 : Squiz.WhiteSpace.OperatorSpacing false positives for some negation operators
  • Thanks to Jakub Chábek and Juliette Reinders Folmer for the patch
• Fixed bug #2674 : Squiz.Functions.FunctionDeclarationArgumentSpacing prints wrong argument name in error message
• Fixed bug #2676 : PSR12.Files.FileHeader locks up when file ends with multiple inline comments
• Fixed bug #2678 : PSR12.Classes.AnonClassDeclaration incorrectly enforcing that closing brace be on a line by itself
• Fixed bug #2685 : File::getMethodParameters() setting typeHintEndToken for vars with no type hint
  • Thanks to Juliette Reinders Folmer for the patch
• Fixed bug #2694 : AbstractArraySniff produces invalid indices when using ternary operator
  • Thanks to Michał Bundyra for the patch
• Fixed bug #2702 : Generic.WhiteSpace.ScopeIndent false positive when using ternary operator with short arrays
