PHP Sniffer & Beautifier for VS Code

This linter plugin for Visual Studio Code provides an interface to phpcs & phpcbf. It will be used with files that have the “PHP” language mode. This extension is designed to use auto configuration search mechanism to apply rulesets to files within a workspace. This is useful for developers who work with many different projects that have different coding standards.

This extension is available on both VS Code Marketplace and Open VSX Registry.

PHPCS Version Support

This extension supports the latest stable version of PHPCS 3.x. If you are using an older version of PHPCS, please upgrade to the latest 3.x version.

NOTE: PHPCS 4.x is not currently supported.

As of v0.0.22, the extension will detect if PHPCS/PHPCBF version 4.x is being used and will display a warning message to the user. Some features may not work as expected when using version 4.x. Please consider downgrading to the latest 3.x version.

Maintenance Status

My focus has shifted away from PHP to .NET development, I'm currently unable to dedicate much time to maintaining this project. However, the extension is fully operational in its current state. If you're interested in contributing as a co-maintainer to address any outstanding issues, please feel free to get in touch with me.

Active Maintainers

In Sept of 2025 yCodeTech was added as a maintainer.

In June 2023 jonathanbossenger reached out to me and offered to help with maintaining the extension. I have added him as a contributor and he will be monitoring new issues and helping me review PRs. I will still be around to help out if needed.

In January 2024 seebeen signed on to be a maintainer for this project and has been granted contributor status. (Currently Inactive)

Installation

Visual Studio Code must be installed in order to use this plugin. If Visual Studio Code is not installed, please follow the instructions here.

Usage

F1 -> PHPCBF: Fix this file

or keyboard shortcut alt+shift+f vs code default formatter shortcut

or right mouse context menu Format Document.

Format on save

You can also use this formatter with Format on Save enabled via the setting editor.formatOnSave.

Format on save has two modes: File and Modified, via the setting editor.formatOnSaveMode. To enable usage of the modified mode, this extension supports the Git Modified filter argument provided by PHPCBF: --filter=GitModified. Just add it to the extension's phpsab.fixerArguments setting.

Multi-Root Workspace Support

This extension now fully supports Multi-Root Workspaces. The extension previously used the first root folder in your workspace to configure and run both phpcs and phpcbf. The new system allows each workspace to be configured and run independently with respect to the root folder of the open file being sniffed. This means you can have phpcs functionality in one folder and have it disabled in another within a workspace.

Single File Mode Support

This extension now supports formatting single files without needing a workspace folder open (single file mode). Both phpcs and phpcbf will work in this mode.

When in single file mode:

• The global user settings are used instead of workspace settings.
• The phpsab.autoRulesetSearch setting is ignored, and will essentially act as if it was set to false (and just return the value as set in phpsab.standard).

A global composer setup is required:

• The phpsab.executablePathCS and phpsab.executablePathCBF settings must be set to the full absolute path of phpcs and phpcbf respectively, OR set them to empty strings to allow the extension to automatically find the global composer installation and resolve the paths to the globally installed phpcs/phpcbf.

• If the phpsab.standard setting is used for a ruleset file then it must be the full absolute path.

Linter Installation

Before using this plugin, you must ensure that phpcs is installed on your system. The preferred method is using composer for both system-wide and project-wide installations.

Once phpcs is installed, you can proceed to install the vscode-phpsab plugin if it is not yet installed.

NOTE: This plugin can detect whether your project has been set up to use phpcbf via composer and use the project specific phpcs & phpcbf over the system-wide installation of phpcs & phpcbf automatically. This feature requires that both composer.json and composer.lock file exist in your workspace root or the phpsab.composerJsonPath in order to check for the composer dependency. If you wish to bypass this feature you can set the phpsab.executablePathCS and phpsab.executablePathCBF configuration settings.

NOTE: phpcbf is installed along with phpcs.

System-wide Installation

The phpcs linter can be installed globally using the Composer Dependency Manager for PHP.

1. Install composer.

2. Require phpcs package by typing the following in a terminal:

   composer global require squizlabs/php_codesniffer

3. You must specifically add the phpcs and phpcbf that you want to used to the global PATH on your system for the extension to auto detect them or set the executablePath for phpcs and phpcbf manually.

Project-wide Installation

The phpcs linter can be installed in your project using the Composer Dependency Manager for PHP.

1. Install composer.

2. Require phpcs package by typing the following at the root of your project in a terminal:

   composer require --dev squizlabs/php_codesniffer

Plugin Installation

1. Open Visual Studio Code.
2. Press Ctrl + P on Windows or Cmd + P on Mac to open the Quick Open dialog.
3. Type ext install phpsab to find the extension.
4. Press Enter or click the cloud icon to install it.
5. Restart Visual Studio Code!

This extension is available on both VS Code Marketplace and Open VSX Registry.

Docker support

If you would like to run phpcs in your docker containers using this extension, a fork exists that will provide you with Docker support.

Basic Configuration

There are various options that can be configured to control how the plugin operates which can be set in your user, workspace or folder preferences.

phpsab.fixerEnable

[ Scope: Resource | Optional | Type: boolean | Default: true ]

This setting controls whether phpcbf fixer is enabled.

phpsab.fixerArguments

[ Scope: Resource | Optional | Type: string[] | Default: [] ]

Passes additional arguments to phpcbf runner.

IMPORTANT: The only additional arguments this extension supports are:

• --filter (values either GitModified, GitStaged, or a path to a custom filter class.)
• --ignore (a comma-separated list of glob patterns matching files and/or directories.)
• --severity (0-10)
• --error-severity (0-10)
• --warning-severity (0-10)
• --ignore-annotations (just a boolean flag.)
• --exclude (a comma-separated list of sniffs to exclude.)

Any other arguments passed or values will be ignored. This is to prevent malicious code from being executed.

NOTE: All arguments passed will be surrounded in double quotes automatically.

Example

{
    phpsab.fixerArguments: ["--ignore=tests/*"]
}

# Translated
phpcbf "--ignore=tests/*" <file>

phpsab.snifferEnable

[ Scope: Resource | Optional | Type: boolean | Default: true ]

This setting controls whether phpcs sniffer is enabled.

• --ignore (a comma-separated list of glob patterns matching files and/or directories.)
• --severity (0-10)
• --error-severity (0-10)
• --warning-severity (0-10)
• --ignore-annotations (just a boolean flag.)
• --exclude (a comma-separated list of sniffs to exclude.)

Any other arguments passed or values will be ignored. This is to prevent malicious code from being executed.

NOTE: All arguments passed will be surrounded in double quotes automatically.

Example

{
    phpsab.snifferArguments: ["--ignore=tests/*"]
}

# Translated
phpcs "--ignore=tests/*" <file>

phpsab.executablePathCS

[ Scope: Resource | Optional | Type: string | Default: null ]

This setting controls the executable path for phpcs. You may specify the absolute path or workspace relative path to the phpcs executable. If omitted, the plugin will try to locate phpcs using you local composer.json, then your global environment path.

NOTE: phpcbf is installed along with phpcs.

{
    "phpsab.executablePathCS": "C:\\Users\\enter-your-username-here\\AppData\\Roaming\\Composer\\vendor\\bin\\phpcs.bat"
}

NOTE: If you are setting this value in the extension settings user interface, make sure to leave out the quotes

C:\\Users\\enter-your-username-here\\AppData\\Roaming\\Composer\\vendor\\bin\\phpcs.bat

phpsab.executablePathCBF

[ Scope: Resource | Optional | Type: string | Default: null ]

This setting controls the executable path for the phpcbf. You may specify the absolute path or workspace relative path to the phpcbf executable. If omitted, the extension will try to locate phpcbf using you local composer.json, then your global environment path.

{
    "phpsab.executablePathCBF": "C:\\Users\\enter-your-username-here\\AppData\\Roaming\\Composer\\vendor\\bin\\phpcbf.bat"
}

NOTE: If you are setting this value in the extension settings user interface, make sure to leave out the quotes

C:\\Users\\enter-your-username-here\\AppData\\Roaming\\Composer\\vendor\\bin\\phpcbf.bat

phpsab.standard

[ Scope: Resource | Optional | Type: string | Default: null ]

This setting controls the coding standard used by phpcs and phpcbf. You may specify the name, absolute path or workspace relative path of the coding standard to use.

NOTE: While using composer dependency manager over global installation make sure you use the phpcbf commands under your project scope !

The following values are applicable:

1. This setting can be set to null, which is the default behavior and uses the default_standard when set in the phpcs configuration or fallback to the Pear coding standard. phpcs may find a ruleset through it's own auto search, in which case that ruleset will be used instead.

   {
       "phpsab.standard": null
   }

   You may set the default_standard used by phpcbf using the following command:

   phpcs --config-set default_standard <value>

   or when using composer dependency manager from the root of your project issue the following command:

   ./vendor/bin/phpcs --config-set default_standard <value>

2. The setting can be set to the name of a built-in coding standard ( ie. PEAR, PSR1, PSR2, PSR12, Squiz, Zend ) and you are good to go.

   {
       "phpsab.standard": "PSR2"
   }

3. The setting can be set to the name of a custom coding standard ( ie. WordPress, Drupal, etc. ). In this case you must ensure that the specified coding standard is installed and accessible by phpcbf.

   {
       "phpsab.standard": "WordPress"
   }

   After you install the custom coding standard, you can make it available to phpcbf by issuing the following command:

   phpcs --config-set installed_paths <path/to/custom/coding/standard>

   or when using composer dependency manager from the root of your project issue the following command:

   ./vendor/bin/phpcs --config-set installed_paths <path/to/custom/coding/standard>

4. The setting can be set to the absolute path to a custom coding standard:

   {
       "phpsab.standard": "/path/to/coding/standard"
   }

   or you can use the path to a custom ruleset:

   {
       "phpsab.standard": "/path/to/project/phpcs.xml"
   }

5. The setting can be set to your workspace relative path to a custom coding standard:

   {
       "phpsab.standard": "./vendor/path/to/coding/standard"
   }

   or you can use the path to your project's custom ruleset:

   {
       "phpsab.standard": "./phpcs.xml"
   }

phpsab.autoRulesetSearch

[ Scope: Resource | Optional | Type: boolean | Default: true ]

Automatically search for any .phpcs.xml, .phpcs.xml.dist, phpcs.xml, phpcs.xml.dist, phpcs.ruleset.xml or ruleset.xml file to use as configuration. Overrides phpsab.standard configuration when a ruleset is found. If phpcs finds a configuration file through auto search this extension should similarly find that configuration file and apply fixes based on the same configuration.

NOTE: This option does not apply for unsaved documents (in-memory). Also, the name of files that are searched for is configurable in this extension.

phpsab.allowedAutoRulesets

[ Scope: Resource | Optional | Type: array | Default: [] ]

An array of filenames that could contain a valid phpcs ruleset.

{
    "phpsab.allowedAutoRulesets": ["phpcs.xml", "special.xml"]
}

phpsab.snifferMode

[ Scope: All | Optional | Type: string | Default: onSave ]

Enum dropdown options to set Sniffer Mode to onSave or onType.

1. onSave: The Sniffer will only update diagnostics when the document is saved.

2. onType: The Sniffer will update diagnostics as you type in a document.

phpsab.snifferTypeDelay

[ Scope: All | Optional | Type: number | Default: 250 ]

When snifferMode is onType this setting controls how long to wait after typing stops to update. The number represents milliseconds.

phpsab.snifferShowSources

[ Scope: All | Optional | Type: boolean | Default: false ]

Determines if the Sniffer includes the source error code of the diagnostic data with error messages (eg. Squiz.WhiteSpace.FunctionSpacing.Before).

phpsab.snifferShowFixabilityIcons

[ Scope: All | Optional | Type: boolean | Default: true ]

Determines if the Sniffer shows auto-fixable icons in the Problems panel (and on-hover intellisense) for each diagnostic.

A check mark (✔️) indicates that the issue is auto-fixable by phpcbf, while a cross mark (❌) indicates that it is not and must be fixed manually.

By default, the icons will be shown, but can be disabled by setting this option to false.

Advanced Configuration

phpsab.composerJsonPath

[ Scope: Resource | Optional | Type: string | Default: composer.json ]

This setting allows you to override the path to your composer.json file when it does not reside at the workspace root. You may specify the absolute path or workspace relative path to the composer.json file.

phpsab.phpExecutablePath

[ Scope: All | Optional | Type: string | Default: null ]

This setting controls the path for the php executable. If you don't have PHP in your system PATH and the extension errors that it cannot find PHP, then you may specify the absolute path to the php executable. This setting will only be used if PHP isn't set in VSCode's built-in PHP setting php.validate.executablePath or Devsense's "PHP Tools" extension setting php.executablePath.

The order of precedence for finding PHP path in the settings is as follows:

1. VSCode's built-in "PHP Language Features" extension setting php.validate.executablePath.
2. Devsense's "PHP Tools" extension setting php.executablePath.
3. This extension's phpsab.phpExecutablePath setting.

phpsab.excludeGlobs

[ Scope: Resource | Optional | Type: array | Default: [ "**/vendor/**", "**/node_modules/**" ] ]

This setting allows you to specify an array of glob patterns to exclude PHP files from being processed by the Sniffer and Fixer. By default, the vendor and node_modules directories are excluded.

This is useful for excluding third-party libraries, dependencies, and intellisense stub files that you do not want to be checked or modified by phpcs/phpcbf.

Diagnosing common errors

phpsab.debug

[ Scope: All | Optional | Type: boolean | Default: false ]

Write debug information to the PHP Sniffer & Beautifier output channel and enable the display of extra notices.

The phpcs report contains invalid json

This error occurs when something goes wrong in phpcs execution such as PHP Notices, PHP Fatal Exceptions, Other Script Output, etc, most of which can be detected as follows:

Execute the phpcbf command in your terminal with --report=json and see whether the output contains anything other than valid json.

Acknowledgements

This extension is based off of the phpcs extension created by Ioannis Kappas, the PHP Sniffer extension create by wongjn and the existing phpcbf extension by Per Søderlind. It uses some portions of these extensions to provide the phpcs & phpcbf functionality with auto config search.
