On this page, enable execution of Composer Dependency Manager commands through the dedicated user interface and appoint the default composer.json for the PhpStorm project.

Path to composer.json In this text box, specify the location of the composer.json that you want to use as default. All the Composer commands invoked from Tools | Composer on the main menu will be executed in accordance with the settings from this configuration file.

You can have several composer.json files in one PhpStorm project. For each composer.json, actions are invoked from its context menu in the editor or in the Project view.

Add packages as libraries Use this check box to configure the open-for-edit status of Composer packages. To protect packages under vendor/*/* against editing, leave the check box selected (this is the default setting).
If you want to edit Composer packages under vendor/*/*, clear the check box.
Synchronize IDE settings with composer.json Select this check box to automatically detect the PHP language level and configure project Source and Test roots based on the configuration from composer.json.
PhpStorm is aware of PSR-0/PSR-4 source roots and of their namespace prefixes declared in the autoload and autoload-dev sections in composer.json. PhpStorm also detects the PHP language level based on the php setting in the require section.
Because composer.json contains the most up-to-date information about the project configuration, this automatic synchronization ensures that the Source and Test folder exactly match the project structure and the correct PHP language level is set automatically. Learn more about PSR and autoload from the Composer official website. For examples and details in synchronizing settings, see PhpStorm blog.
PHP interpreter Choose one of the configured PHP interpreters from the list. See Configuring Remote PHP Interpreters for details.
Path to composer.phar In this text box, specify the location of the composer.phar archive.
