PhpStorm 2020.2 Help

Reformat and rearrange code

PhpStorm lets you reformat your code according to the requirements you've specified in the Code Style settings. However, if you use EditorConfig in your project, options specified in the .editorconfig file override the ones specified in the code style settings when you reformat the code.

To access the settings, in the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style. See Configuring code style for details.

You can reformat a part of code, the whole file, group of files, a directory, and a module. You can also exclude part of code or some files from the reformatting.

Reformat a code fragment in a file

  1. In the editor, select a code fragment you want to reformat.

  2. From the main menu, select Code | Reformat Ctrl+Alt+L.

Reformat a file

  1. Either open your file in the editor and press Ctrl+Alt+Shift+L or in the Project tool window, right-click the file and select Reformat Code.

  2. In the dialog that opens, if you need, select the following reformatting options:

    • Optimize imports: select this option if you want to remove unused imports, add missing ones, or organize import statements.

      For more information, refer to the Optimize imports section.

    • Rearrange entries: select this option if you need to rearrange your code based on the arrangement rules specified in the code style settings.

    • Clean up code: select this option to run the code cleanup inspections.

    Reformat Files dialog

    Click OK.

    If you want to see the exact changes made to your code during the reformatting, use the Local History feature.

Reformat line indents

You can reformat line indents based on the specified settings.

  1. While in the editor, select the necessary code fragment and press Ctrl+Alt+I.

  2. If you need to adjust indentation settings, in the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style.

  3. On the appropriate language page, on the Tabs and Indents tab, specify the appropriate indents options and click OK.

Exclude code or a file from reformatting

You can exclude a group of files or part of code from reformatting.

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style.

  2. On the Formatter Control tab, select the Enable formatter markers in comments checkbox. The Scope area becomes active

  3. In the Scope area, click the Add icon to add a scope where you can specify files that you want to exclude from reformatting.

If you try reformatting the excluded file, PhpStorm displays a popup notifying you that formatting for this file is disabled. If you need, click the link in the popup to open the Code Style settings page and change the exclusion scope.

Exclude code fragments from reformatting in the editor

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style and select the Enable formatter markers in comments checkbox on the Formatter Control tab.

  2. In the editor, at the beginning of a region that you want to exclude, create a line comment Ctrl+/ and type //@formatter:off, at the end of the region, again create a line comment and type //@formatter:on.

Keep existing formatting

You can select formatting rules which will be ignored when you reformat the code. For example, you can adjust the IDE to keep simple methods and functions in one line, whereas normally they are expanded into multiple lines after code reformatting.

  1. Go to Settings/Preferences | Editor | Code Style, select your programming language, and open the Wrapping and Braces tab.

  2. In the Keep when reformatting section, select the formatting rules which you want to ignore and deselect those which should be applied.

  3. Reformat your code (Ctrl+Alt+L).

PhpStorm will reformat your code in accordance with the current style settings, keeping existing formatting for the rules which you've selected.

Rearrange code

You can rearrange your code according to the arrangement rules set in the Code Style. PHP page of the Settings/Preferences dialog.

Configure grouping rules

Grouping rules let you keep related class methods together.

  • In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style | PHP. On the Arrangement tab, choose the grouping options in the Grouping rules area.

    Grouping rules example

    For the Keep dependent methods together option, you can select depth-first order or breadth-first order. The former will arrange the methods according to the nesting hierarchy; the latter will group together the sibling methods from the same nesting level.

    class foo { public function parent() { $this->child1(); $this->child2(); } private function child1() { $this->nested1(); } private function nested1() { $this->nested2(); } private function nested2() { } private function child2() { } }
    class foo { public function parent() { $this->child1(); $this->child2(); } private function child1() { $this->nested1(); } private function child2() { } private function nested1() { $this->nested2(); } private function nested2() { } }

Create matching rules

Matching rules let you define elements order as a list of rules, where every rule has a set of matching conditions, such as modifier or type.

  • In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style | PHP. On the Arrangement tab, click the Add button and provide the rule parameters in the Matching rules area.

    • Use the Type and Modifier filters to choose the code constructs and their visibility modifiers that should be regulated by the rule. Note that double-clicking a filter negates the condition.

    • Use the Name field to specify entry names the rule should affect. This filter matches only entry names, such as property 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.

    • To sort code entries alphabetically, select the appropriate matching rules entry and set the Order field to order by name.

      Matching rules example

    You can also create groups (aliases) of rules and refer to them when creating a new matching rule.

Create rule aliases

With aliases, you can group several arrangement rules into a single entity and refer to it when you adding a new matching rule.

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style | PHP. On the Arrangement tab, click Configure matching rules aliases.

  2. In the Rules Alias Definitions dialog that opens, add a group name and its rules.

    Rules Alias Definitions

The created alias can now be referred to when adding a matching rule.

Matching rules alias example

Create section rules

Section rules let you move methods or variables into the sections that you have defined.

  • In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style | PHP. On the Arrangement tab, click the Add Section Rule button and provide the rule parameters in the Matching rules area.

    For example, you can create the following section rule:

    A section matching rule example

    After the arrangement, methods in the class will be rearranged as specified in the created section rule and will be surrounded by comments:

    //methods start public function test() {} private function a() { return 1; } static function r() {} //methods end

Rearrange code entries

  1. In the Settings/Preferences dialog Ctrl+Alt+S , go to Editor | Code Style.

  2. Select a language for which you want to create arrangement rules.

  3. On the Arrangement tab, specify the appropriate options such as grouping and matching rules.

  4. Click OK to save the changes.

  5. In the editor, select the code entries you want to rearrange and from the main menu, select Code | Rearrange Code.
