Code Style. PHP

Use this page to configure formatting options for PHP files. When you change these settings, the Preview pane shows how this will affect your code.

Set from...

Click this link to choose the base for the current language default code style from the list, that appears. The list contains two options:

  • Language: choose this option to inherit the coding style settings from another language. Select the source language from the list, that opens. Only the settings that are applicable to the current language are taken. All the other settings are not affected.

  • Predefined code style: choose this option to use the coding standards defined for a specific framework. Select one of the following frameworks from the list:

Tabs and Indents

ItemDescription
Use tab character
  • If this checkbox is selected, tab characters are used:

    • On pressing the Tab key

    • For indentation

    • For code reformatting

  • When the checkbox is cleared, PhpStorm uses spaces instead of tabs.

Smart tabs
  • If this checkbox is selected, the part of indentation defined by the nesting of code blocks, is made of the tabs and (if necessary) spaces, while the part of indentation defined by the alignment is made only of spaces.

    Code style with Smart Tabs on
  • If this checkbox is cleared, only tabs are used. This means that a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment.

    Code style with Smart Tabs off

The Smart tabs checkbox is available if the Use tab character checkbox is selected.

Tab sizeIn this field, specify the number of spaces included in a tab.
IndentIn this field, specify the number of spaces to be inserted for each indent level.
Continuation indentIn this field, specify the number of spaces to be inserted between the elements of an array, in expressions, method declarations and method calls.
Keep indents on empty linesIf this checkbox is selected, PhpStorm will keep indents on the empty lines as if they contained some code.
If this checkbox is cleared, PhpStorm will delete the tab characters and spaces.
Indent code in PHP tagsSelect this checkbox to have the code enclosed in <?php> tags indented against the opening <?php tag.

ItemDescription
Hard wrap atUse this field to specify a margin space required on the right side of an element. If you select the Default option, then a value of the right margin from the global settings is used.
Wrap on typing

Use these settings to specify how the edited text is fitted in the specified Hard wrap at:

  • Default: in this case PhpStorm uses the Wrap on typing option that is specified in the global settings.

  • Yes: in this case PhpStorm uses the value specified in the Right Margin field.

  • No: in this case this option is switched off and a line can exceed the value specified in the right margin.

Visual guidesUse this field to specify multiple right margins. You can leave a default value or enter the number of spaces for your margin. If you want to specify several margins, enter numbers separated by comma.

  • Modifier: use this filter to select the types of modifiers for the rule.
    Note that clicking a modifier keyword twice negates 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 so on. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name.

  • Order: use this 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.

the Sort Alphabetically buttonThis icon appears when you select Order by Name from the Order list. The icon indicates that the items in this rule are sorted alphabetically.
