PhpStorm 2023.3 Help

PHP CS Fixer

In addition to built-in coding assistance, PhpStorm provides checking the source code through integration with the PHP CS Fixer tool, which detects coding standards problems in your code.

To use PHP CS Fixer from PhpStorm instead of the command line, you need to register it in PhpStorm and configure it as a PhpStorm code inspection. Once installed and enabled in PhpStorm, the tool is available in any opened PHP file, and no additional steps are required to launch it. The on-the-fly code check is activated upon every update in the file thus making it easy to get rid of discovered problems.

Issues reported by PHP CS Fixer on the fly are highlighted in the editor in the same way as the errors and warnings reported by PhpStorm's internal code inspections. When the tool is run in batch mode, the errors and warnings are displayed in the Problems tool window. Each message has the PHP CS Fixer prefix to distinguish it from PhpStorm internal inspections.

You can have predefined rules applied or define your own custom set of rules.

Prerequisites

Prior to integrating PHP CS Fixer in PhpStorm, make sure the following prerequisites are met:

  • You are working with PHP CS Fixer version 2.8.0 and later.

  • The directory containing the PHP engine executable must be added to the system path. This allows code quality tool scripts to execute calls to the system-wide PHP engine.

  • For Docker Compose-based remote interpreters, make sure to use docker-compose exec mode to avoid spawning additional containers.

    1. In the Settings dialog (Ctrl+Alt+S) , go to PHP.

    2. On the PHP page that opens, click the Browse button next to the CLI Interpreter list.

    3. In the CLI Interpreters dialog that opens, set the Lifecycle mode for the selected interpreter to Connect to existing container ('docker-compose exec').

Install and configure PHP CS Fixer

Install PHP CS Fixer with Composer

When you install PHP CS Fixer with Composer, PhpStorm automatically downloads the necessary scripts, registers them in the IDE, and, optionally, enables and configures the corresponding code inspection.

  1. Inside composer.json, add the friendsofphp/php-cs-fixer dependency record to the require or require-dev key. To get code completion for the package name and version, press Ctrl+Space.

  2. Do one of the following:

    • Click the Install shortcut link on top of the editor panel.

    • If the Non-installed Composer packages inspection is enabled, PhpStorm will highlight the declared dependencies that are not currently installed. Press Alt+Enter and select whether you want to install a specific dependency or all dependencies at once.

Clicking the Settings button next to the package record in the composer.json editor gutter will take you to the corresponding Settings page where you can configure PHP CS Fixer manually.

Reset PHP CS Fixer configuration

After PHP CS Fixer is initially configured, further modifications in composer.json will not affect the inspection configuration. To apply newer changes, reset the PHP CS Fixer configuration.

  1. In the Settings dialog (Ctrl+Alt+S) , navigate to PHP | Quality Tools | PHP CS Fixer.

  2. Click the Browse button next to the Configuration list.

  3. In the PHP CS Fixer dialog that opens, empty the PHP CS Fixer path field.

  4. Update the project Composer dependencies by clicking Update on top of the composer.json editor panel. For more information, refer to Update dependencies.

PhpStorm will perform the PHP CS Fixer configuration anew and thus apply the changes in composer.json.

Configure PHP CS Fixer in PhpStorm

When you install PHP CS Fixer with Composer, PhpStorm automatically detects PHP CS Fixer's executable file in the vendor/bin folder and sets the PHP interpreter configured in the system path to run it.

In Settings (Ctrl+Alt+S) | PHP | Quality Tools | PHP CS Fixer, you can change the default PHP interpreter, set the path to a manually downloaded and installed PHP CS Fixer executable file, or add some options to be passed to PHP CS Fixer when running it in PhpStorm.

PHP CS Fixer settings
  • Configuration: in this field, you can change the default PHP interpreter and path to the PHP CS Fixer executable file.

    1. To only change the interpreter, select the required item from the list of local and remote PHP interpreters configured in your project.

    2. To change the path to the PHP CS Fixer executable file, or both the interpreter and the path, click the Browse button next to the Configuration list to open the PHP CS Fixer dialog and edit the fields there as described on the PHP CS Fixer Dialog reference page.

  • Show ignored files: use this setting to exclude files from PHP CS Fixer validation inspection. For more information, refer to the Quality Tools reference page.

  • Options: in this area, add the options to run PHP CS Fixer as a PhpStorm inspection with. Edit the fields there as described on the PHP CS Fixer reference page.

Enable PHP CS Fixer as a PhpStorm inspection

There are two ways to set up PHP CS Fixer as a PhpStorm inspection: automatically during PHP CS Fixer installation with Composer, or manually in PhpStorm's inspections settings.

Enable the PHP CS Fixer inspection with Composer

You can include the information on the default and custom PHP CS Fixer rulesets inside the scripts section of composer.json. When you install or update project dependencies, the specified rulesets will be detected and the PHP CS Fixer validation inspection will be enabled automatically.

If no ruleset is specified in the scripts section of composer.json, PhpStorm will additionally check the project root to locate the ruleset with the .php_cs or .php_cs.dist default name. If the file is present, it will be automatically selected as the inspection's Custom ruleset.

  • In the scripts section of composer.json, add the php-cs-fixer PHP CS Fixer launch command into one of the leaf elements.

    Provide the --rules argument to denote the coding standard used. For example, adding the following record will set the coding standard to PSR1:

    "scripts": { "php-cs-fixer": "php-cs-fixer --rules=@PSR1" }

    Alternatively, provide the --config argument and the path to the ruleset file, which will set the coding standard to Custom:

    "scripts": { "php-cs-fixer": "php-cs-fixer --config=./.php_cs" }

Enable PHP CS Fixer validation in Inspections settings

  1. In the Settings dialog (Ctrl+Alt+S) , click Inspections under Editor.

  2. On the Inspections page that opens, expand the PHP | Quality Tools node and select the checkbox next to PHP CS Fixer validation.

    Select PHP CS Fixer validation checkbox
  3. On the right-hand pane of the page, configure how PhpStorm handles the PHP CS Fixer inspection output:

    1. Scope: choose the scope to limit the inspection application to.

    2. Severity: choose the severity degree for the inspection. The selected value determines how seriously the detected discrepancies will be treated by PhpStorm and presented in the inspection results.

    3. Highlighting in editor: choose how the issues detected by the inspection are highlighted in the editor.

Run PHP CS Fixer in batch mode

  1. In the main menu, go to Code | Inspect code.

  2. In the Specify Inspection Scope dialog that opens, select the inspection profile from the list, or click Configure to open the Inspections dialog and configure a new profile.

    You can also click Configure to check which fixes will be applied within the scope of the selected inspection profile, and make sure that the PHP CS Fixer validation inspection is enabled.

  3. View the inspection results in the Problems tool window. Errors and warnings reported by PHP CS Fixer are prefixed with PHP CS Fixer: to distinguish them from PhpStorm internal inspections.
