PHP-secific formatting settings for Tabs and Indents

See Common Code Style Options: Tabs and Indents for the settings that are common for all languages.

ItemDescription
Indent as template language unless PHP-only
  • When this check box is selected, IntelliJ IDEA applies the indentation style specified for the template language of the source code into which PHP fragments are embedded. If the PHP code is not surrounded with any other code, the PHP style is applied depending on the status of the Use tab character check box.
  • When this check box is cleared, the PHP style is applied no matter whether the PHP code fragment is embedded or the entire file is .php.

PHP-specific formatting settings for Spaces

See Common Code Style Options: Spaces for the settings that are common for all languages.

Select or clear the check boxes to have spaces inserted, not inserted, or removed in the following PHP contexts:

ItemDescription
Before Parentheses
  • Array initializer parentheses

    Select this check box to have a space inserted before the opening parenthesis in array declarations, such as:

    $array = array (0 => "zero", 1 => "one");

    If the check box is cleared, no space is inserted and the code looks as follows:

    $array = array(0 => "zero", 1 => "one");

Around Operators
  • Concatenation

    Select this check box to have spaces inserted before and after the concatenation operator (.) so the code looks as follows:

    echo "The result is " . $i;

    When the check box is cleared, no spaces are inserted around the concatenation operator so the code looks as follows:

    echo "The result is ".$i;

Before Left Brace
  • Class left brace

    Select this check box to have a space inserted between the class name and the opening brace in class declarations:

    class Class1 { function Foo() }

    When the check box is cleared, no space is inserted:

    class Class1{ function Foo() }

    Selecting or clearing the check box is relevant only when Braces placement in class declarations is set to End of line on the Wrapping and Braces tab.

In Ternary Operator (?:) Select the check boxes in this section to have spaces automatically inserted before and after ?, before and after :, and between ? and : in ternary (conditional) operators.
Other Select the check boxes in this section to have spaces automatically inserted before and after commas, semicolons, unary NOT operators (!), and after type casts.
  • After type cast

    When this check box is selected, IntelliJ IDEA automatically inserts a space after the closing parentheses of a cast: $fst = (string) $foo;

    If the check box is cleared, no spaces is inserted and the casted variable sticks to the cast: $fst = (string)$foo;

PHP-specific formatting settings for Wrapping and Braces

See Common Code Style Options: Wrapping and Braces for the settings that are common for all languages.

ItemDescription
Braces placement In this section, choose the position for opening braces in declarations of namespaces, classes, and functions, in loops, and in other constructions. Choose the required position from the drop-down list, the available options are:
  • End of line - select this option to have the opening brace placed at the declaration line end.
  • Next line if wrapped - select this option to have the opening brace placed at the beginning of the line after the multiline declaration line.
  • Next line - select this option to have the opening brace placed at the beginning of the line after the declaration line.
  • Next line shifted - select this option to have the opening brace placed at the line after the declaration line being shifted to the corresponding indent level.
  • Next line each shifted - select this option to have the opening brace placed at the line after the declaration line being shifted to the corresponding indent level, and have the next line shifted to the next indent level as well.
Extends/implements list In this section, configure wrapping and subsequent alignment of extend and implements lists:
  • Do not wrap - when this option is selected, no special wrapping style is applied.

    With this option selected, the nested alignment and braces settings are ignored.

  • Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation.
  • Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation.
  • Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped so that there is one element per line with proper indentation.
  • Align when multiline

    When this check box is selected, each item in an extends or an implements list, which after wrapping starts on a new line, are aligned by the first item, which remains unwrapped:

    abstract class Foo extends Class1 implements Class2, Class8 { }

    When the check box is cleared, the position of each item in a wrapped list is determined by the chosen indentation level.

    The status of the check box affects the formatting only if you have chosen to wrap lists, if the Do not wrap option is chosen, selecting or clearing the check box has no effect.

Extends/implements keyword In this section, configure wrapping for the extends and implements keywords in class declarations.

If you choose the Do not wrap option, no wrapping will be applied, if you choose Wrap if long or Wrap always, each keyword and each item in an extends or implements list will be displayed on a new line:

abstract class Foo extends Class1 implements Class2, Class8 { }

Function declaration parameters In this area, configure formatting in declarations of functions and methods.
  • Keep ')' and '{' on one line

    When this check box is cleared, the opening curly brace is moved to the next line:

    function Foo() { }

    When the check box is selected, the opening curly brace is displayed on the same line as the function parameters:

    function Foo() { }

Chained method calls In this section, configure wrapping and subsequent alignment of chained calls.
  • Do not wrap - when this option is selected, no special wrapping style is applied.

    With this option selected, the nested alignment and braces settings are ignored.

  • Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation.
  • Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation.
  • Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped so that there is one element per line with proper indentation.
  • Align when multiline

    When the check box is selected, each called method, which after wrapping is positioned on a new line, is aligned by the first one, which remains unwrapped:

    $x = $x->one( "a", "b" ) ->two( "c", "d", "e" ) ->three( "fg" ) ->four;

    When the check box is cleared, the position of each item in a wrapped list is determined by the chosen indentation level.

    The status of the check box affects the formatting only if you have chosen to wrap lists, if the Do not wrap option is chosen, selecting or clearing the check box has no effect.

  • Place ';' on new line

    When the check box is cleared, the semicolon (;) is displayed after the last item in a chained call. If the check box is selected, the semicolon is moved to a new line:

    $x = $x->one( "a", "b" ) ->two( "c", "d", "e" ) ->three( "fg" ) ->four ;

Assignment statement In this section, configure wrapping and subsequent alignment in assignment statements.
  • Do not wrap - when this option is selected, no special wrapping style is applied.

    With this option selected, the nested alignment and braces settings are ignored.

  • Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation.
  • Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation.
  • Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped so that there is one element per line with proper indentation.
  • Assignment sign on new line
  • Align consecutive assignments

    When this check box is selected, the assignment signs in consecutive assignment statements are aligned by the rightmost one:

    $y = foo( $x ); $intermediate = foo( $intermediate ); $result = $result . $y . $intermediate;

    When this check box is cleared, no alignment is applied:

    $y = foo( $x ); $intermediate = foo( $intermediate ); $result = $result . $y . $intermediate;

Class field/constant groups In this section, configure wrapping and subsequent alignment within lists of class properties (fields) or class constants.
  • Align fields in columns
  • Align constants
Array initializer In this section, configure wrapping and subsequent alignment in array declarations.
  • Do not wrap - when this option is selected, no special wrapping style is applied.

    With this option selected, the nested alignment and braces settings are ignored.

  • Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation.
  • Wrap always - select this option to have all elements in lists wrapped so that there is one element per line with proper indentation.
  • Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped so that there is one element per line with proper indentation.
  • Align when multiline

    When the check box is selected and the New line after '(' check box is cleared, each element, which after wrapping is positioned on a new line, is aligned by the first one, which remains unwrapped:

    $colours = array( "blue", "red", "white", "green", "yellow" );

    When both the Align when multiline and the New line after '(' check boxes are selected, all the elements ae aligned according to the indentation settings:

    $colours = array( "blue", "red", "white", "green", "yellow" );

    Selecting or clearing the Align when multiline and the New line after '(' check boxes affects the formatting only if you have chosen to wrap lists, if the Do not wrap option is chosen, the status of the check boxes has no effect.

  • New line after '('

    When this check box is selected, the first element of the array is displayed on a new line and all the elements of the array are aligned according to the indentation settings, regardless of the status of the Align when multiline check box.

    When this check box is cleared, the first element of the array remains on the same line, and the other elements are aligned according to the indentation settings.

  • Place ')' on new line
Modifier list
  • Wrap after modifier list

    When this check box is selected, the code is wrapped after a list of visibility modifiers:

    protected function Foo() { }

    When the check box is cleared, no wrapping is performed:

    protected function Foo() { }

Blank lines

Use this tab to define where and how many blank lines you want IntelliJ IDEA to retain and insert in your code after reformatting. For each type of location, specify the number of blank lines to be inserted. The results are displayed in the Preview pane.

ItemDescription

  • Ignore Logic exceptions: If this check box is selected, exceptions caused by the error in the program logic (either based on LogicException or any of its subclasses), are ignored.

Other

ItemDescription
Indent code in PHP tagsSelect this check box to have the code enclosed in <?php> tags indented against the opening <?php tag.
Convert True/False constants to upper caseSelect this check box to have the true and false constants displayed in the upper case.
Convert Null constant to upper caseSelect this check box to have the null constant displayed in the upper case.
Blank line before return statementSelect this check box to have IntelliJ IDEA automatically insert a blank line before each return statement.
Spaces around variables/expressions in brackets
  • Select this check box to have IntelliJ IDEA insert spaces inside brackets during reformatting only if the brackets enclose a variable or an expression. This setting affects reformatting only if you have not configured force insertion of spaces inside brackets by selecting the Brackets check box under the Within node in the Spaces tab.

    This option helps you keep your code in accordance with the WordPress PHP Coding Standards.

  • If this check box is cleared, the spaces insertion policy depends on the settings under the Within node in the Spaces tab regardless of the type of content inside brackets:
    • if the Brackets check box is selected, spaces are always inserted
    • if the Brackets check box is cleared, spaces are never inserted.
Code CommentingIn this area, configure the code style options to be applied to comments.
  • Line comment at first column: - select this check box to have line comments start at the first column, without any indentation. Note that no extra blank spaces are added after the line comment characters. The check box is by default selected.

    When the check box is cleared, the line comments start from the minimum indentation within the selected code block to be commented.

Array declaration style
  • Force short declaration style: select this check box to have IntelliJ IDEA replace the array() constructs with [] in array declarations during reformatting.

    When the check box is cleared, the traditional literal style in array declarations is preserved after reformatting.

  • Align key-value pairs: select this check box to have the => separators in key-value assignments aligned.
  • Add a comma after last element in multiline array: select this check box to have IntelliJ IDEA automatically insert a comma after the last item in declarations of multiline arrays to meet the required coding standard, for example, the Symfony coding standards .
See Arrays. Syntax for details.

Arrangement

In this tab, define a set of rules to re-arrange your PHP code according to your preferences.

ItemDescription
Grouping RulesUse this area to set the grouping rules.
  • Keep getters and setters together

    Select this check box to keep getter and setter methods together. By default, this check box is selected.

  • Keep overridden methods together

    Select this check box to group the overridden methods together by class and interface. In order: list, select keep or by name options.

  • Keep dependent methods together

    Select this check box to group the dependent methods together. In order: list, select depth-first or breadth-first options.

Matching rulesUse this area to define elements order as a list of rules, where every rule has a set of matches such as modifier or type.
  • add - use this button to add a rule. The empty rule dialog window opens.
  • delete - use this button to remove the rule from the list.
  • edit1 - use this button to edit an existing rule. To see this button, navigate to the rule that you want to edit and click on the button. In pop-up window that opens, modify the rule fields.
  • arrowUp arrowDown - use these buttons to move the selected rule up or down.
Empty ruleUse this window to create a new matching rule or edit an existing one. You can select from the following filters:
  • Type - use this filter to choose classes or methods for your rule.
    Note that clicking twice on the type keyword will negate the condition.
  • Name - use this field to specify entry names in the rule. This filter matches only entry names such as field names, method names, class names and etc. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name.
  • Order - use this drop-down list to select the sorting order for the rule. This option is useful when more than one element uses the same matching rule. In this case, selecting Keep order will keep the same order as was set before the rearrangement and selecting Order by Name will sort the elements with the same matching rule by their names.
  • Aliases - this option displays aliases that were defined in the Rules Alias Definition dialog. You can remove the ones you do not need.
icon_sort This icon appears when you select Order by Name in Order option. The icon indicates that the items in this rule are alphabetized.
