PSR-12 Standard Ready

PHP_CodeSniffer has included an in-progress PSR-12 standard since 3.3.0, but this release includes the completed standard. You can now check your code using the PSR-12 standard: 

phpcs --standard=PSR12 /path/to/code

Most of the errors found can also be automatically fixed by PHPCBF: 

phpcbf --standard=PSR12 /path/to/code

Changelog

  • Added support for PHP 7.4 typed properties
    • The nullable operator is now tokenized as T_NULLABLE inside property types, as it is elsewhere
    • To get the type of a member var, use the File::getMemberProperties() method, which now contains a type array index
      • This contains the type of the member var, or a blank string if not specified
      • If the type is nullable, the return type will contain the leading ?
      • If a type is specified, the position of the first token in the type will be set in a type_token array index
      • If a type is specified, the position of the last token in the type will be set in a type_end_token array index
      • If the type is nullable, a nullable_type array index will also be set to TRUE
      • If the type contains namespace information, it will be cleaned of whitespace and comments in the return value
  • The PSR1 standard now correctly bans alternate PHP tags
    • Previously, it only banned short open tags and not the pre-7.0 alternate tags
  • Added support for only checking files that have been locally staged in a git repo
    • Use --filter=gitstaged to check these files
    • You still need to give PHPCS a list of files or directories in which to apply the filter
    • Thanks to Juliette Reinders Folmer for the contribution
  • JSON reports now end with a newline character
  • The phpcs.xsd schema now validates phpcs-only and phpcbf-only attributes correctly
    • Thanks to Juliette Reinders Folmer for the patch
  • The tokenizer now correctly identifies inline control structures in more cases
  • All helper methods inside the File class now throw RuntimeException instead of TokenizerException
    • Some tokenizer methods were also throwing RuntimeExpection but now correctly throw TokenizerException
    • Thanks to Juliette Reinders Folmer for the patch
  • The File::getMethodParameters() method now returns more information, and supports closure USE groups
    • If a type hint is specified, the position of the last token in the hint will be set in a type_hint_end_token array index
    • If a default is specified, the position of the first token in the default value will be set in a default_token array index
    • If a default is specified, the position of the equals sign will be set in a default_equal_token array index
    • If the param is not the last, the position of the comma will be set in a comma_token array index
    • If the param is passed by reference, the position of the reference operator will be set in a reference_token array index
    • If the param is variable length, the position of the variadic operator will be set in a variadic_token array index
  • The T_LIST token and it's opening and closing parentheses now contain references to each other in the tokens array
    • Uses the same parenthesis_opener/closer/owner indexes as other tokens
    • Thanks to Juliette Reinders Folmer for the patch
  • The T_ANON_CLASS token and it's opening and closing parentheses now contain references to each other in the tokens array
    • Uses the same parenthesis_opener/closer/owner indexes as other tokens
    • Only applicable if the anon class is passing arguments to the constructor
    • Thanks to Juliette Reinders Folmer for the patch
  • The PHP 7.4 T_BAD_CHARACTER token has been made available for older versions
    • Allows you to safely look for this token, but it will not appear unless checking with PHP 7.4+
  • Metrics are now available for Squiz.WhiteSpace.FunctionSpacing
    • Use the info report to see blank lines before/after functions
    • Thanks to Juliette Reinders Folmer for the patch
  • Metrics are now available for Squiz.WhiteSpace.MemberVarSpacing
    • Use the info report to see blank lines before member vars
    • Thanks to Juliette Reinders Folmer for the patch
  • Added Generic.ControlStructures.DisallowYodaConditions sniff
    • Ban the use of Yoda conditions
    • Thanks to Mponos George for the contribution
  • Added Generic.PHP.RequireStrictTypes sniff
    • Enforce the use of a strict types declaration in PHP files
  • Added Generic.WhiteSpace.SpreadOperatorSpacingAfter sniff
    • Checks whitespace between the spread operator and the variable/function call it applies to
    • Thanks to Juliette Reinders Folmer for the contribution
  • Added PSR12.Classes.AnonClassDeclaration sniff
    • Enforces the formatting of anonymous classes
  • Added PSR12.Classes.ClosingBrace sniff
    • Enforces that closing braces of classes/interfaces/traits/functions are not followed by a comment or statement
  • Added PSR12.ControlStructures.BooleanOperatorPlacement sniff
    • Enforces that boolean operators between conditions are consistently at the start or end of the line
  • Added PSR12.ControlStructures.ControlStructureSpacing sniff
    • Enforces that spacing and indents are correct inside control structure parenthesis
  • Added PSR12.Files.DeclareStatement sniff
    • Enforces the formatting of declare statements within a file
  • Added PSR12.Files.FileHeader sniff
    • Enforces the order and formatting of file header blocks
  • Added PSR12.Files.ImportStatement sniff
    • Enforces the formatting of import statements within a file
  • Added PSR12.Files.OpenTag sniff
    • Enforces that the open tag is on a line by itself when used at the start of a php-only file
  • Added PSR12.Functions.ReturnTypeDeclaration sniff
    • Enforces the formatting of return type declarations in functions and closures
  • Added PSR12.Properties.ConstantVisibility sniff
    • Enforces that constants must have their visibility defined
    • Uses a warning instead of an error due to this conditionally requiring the project to support PHP 7.1+
  • Added PSR12.Traits.UseDeclaration sniff
    • Enforces the formatting of trait import statements within a class
  • Generic.Files.LineLength ignoreComments property now ignores comments at the end of a line
    • Previously, this property was incorrectly causing the sniff to ignore any line that ended with a comment
    • Now, the trailing comment is not included in the line length, but the rest of the line is still checked
  • Generic.Files.LineLength now only ignores unwrappable comments when the comment is on a line by itself
    • Previously, a short unwrappable comment at the end of the line would have the sniff ignore the entire line
  • Generic.Functions.FunctionCallArgumentSpacing no longer checks spacing around assignment operators inside function calls
    • Use the Squiz.WhiteSpace.OperatorSpacing sniff to enforce spacing around assignment operators
      • Note that this sniff checks spacing around all assignment operators, not just inside function calls
    • The Generic.Functions.FunctionCallArgumentSpacing.NoSpaceBeforeEquals error has been removed
      • use Squiz.WhiteSpace.OperatorSpacing.NoSpaceBefore instead
    • The Generic.Functions.FunctionCallArgumentSpacing.NoSpaceAfterEquals error has been removed
      • use Squiz.WhiteSpace.OperatorSpacing.NoSpaceAfter instead
    • This also changes the PEAR/PSR2/PSR12 standards so they no longer check assignment operators inside function calls
      • They were previously checking these operators when they should not have
    • Thanks to Juliette Reinders Folmer for the patch
  • Generic.WhiteSpace.ScopeIndent no longer performs exact indents checking for chained method calls
    • Other sniffs can be used to enforce chained method call indent rules
    • Thanks to Pieter Frenssen for the patch
  • PEAR.WhiteSpace.ObjectOperatorIndent now supports multi-level chained statements
    • When enabled, chained calls must be indented 1 level more or less than the previous line
    • Set the new multilevel setting to TRUE in a ruleset.xml file to enable this behaviour
    • Thanks to Marcos Passos for the patch
  • PSR2.ControlStructures.ControlStructureSpacing now allows whitespace after the opening parenthesis if followed by a comment
    • Thanks to Michał Bundyra for the patch
  • PSR2.Classes.PropertyDeclaration now enforces a single space after a property type keyword
    • The PSR2 standard itself excludes this new check as it is not defined in the written standard
    • Using the PSR12 standard will enforce this check
  • Squiz.Commenting.BlockComment no longer requires blank line before comment if it's the first content after the PHP open tag
    • Thanks to Juliette Reinders Folmer for the patch
  • Squiz.Functions.FunctionDeclarationArgumentSpacing now has more accurate error messages
    • This includes renaming the SpaceAfterDefault error code to SpaceAfterEquals, which reflects the real error
  • Squiz.Functions.FunctionDeclarationArgumentSpacing now checks for no space after a reference operator
    • If you don't want this new behaviour, exclude the SpacingAfterReference error message in a ruleset.xml file
  • Squiz.Functions.FunctionDeclarationArgumentSpacing now checks for no space after a variadic operator
    • If you don't want this new behaviour, exclude the SpacingAfterVariadic error message in a ruleset.xml file
  • Squiz.Functions.MultiLineFunctionDeclaration now has improved fixing for the FirstParamSpacing and UseFirstParamSpacing errors
  • Squiz.Operators.IncrementDecrementUsage now suggests pre-increment of variables instead of post-increment
    • This change does not enforce pre-increment over post-increment; only the suggestion has changed
    • Thanks to Juliette Reinders Folmer for the patch
  • Squiz.PHP.DisallowMultipleAssignments now has a second error code for when assignments are found inside control structure conditions
    • The new error code is Squiz.PHP.DisallowMultipleAssignments.FoundInControlStructure
    • All other multiple assignment cases use the existing error code Squiz.PHP.DisallowMultipleAssignments.Found
    • Thanks to Juliette Reinders Folmer for the patch
  • Squiz.WhiteSpace.FunctionSpacing now applies beforeFirst and afterLast spacing rules to nested functions
    • Previously, these rules only applied to the first and last function in a class, interface, or trait
    • These rules now apply to functions nested in any statement block, including other functions and conditions
  • Squiz.WhiteSpace.OperatorSpacing now has improved handling of parse errors
    • Thanks to Juliette Reinders Folmer for the patch
  • Squiz.WhiteSpace.OperatorSpacing now checks spacing around the instanceof operator
    • Thanks to Jakub Chábek for the patch
  • Squiz.WhiteSpace.OperatorSpacing can now enforce a single space before assignment operators
    • Previously, the sniff this spacing as multiple assignment operators are sometimes aligned
    • Now, you can set the ignoreSpacingBeforeAssignments sniff property to FALSE to enable checking
    • Default remains TRUE, so spacing before assignments is not checked by default
    • Thanks to Jakub Chábek for the patch
