vscode-phpcs

This linter plugin for Visual Studio Code provides an interface to phpcs. It will be used with files that have the “PHP” language mode.

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.

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-phpcs plugin if it is not yet installed.

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

NOTE: You can also install phpcs on your system using pear or even manually but is beyond the scope of this plugin.
