The page is available only when the PHP and the Command Line Tool Support plugins are enabled. The plugins are not bundled with IntelliJ IDEA, but they can be installed from the JetBrains plugin repository as described in Managing Plugins. Once enabled, the plugins are available at the IDE level, that is, you can use them in all your IntelliJ IDEA projects.

On this page, enable execution of Composer Dependency Manager commands through the dedicated user interface and appoint the default composer.json for the IntelliJ IDEA 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 IntelliJ IDEA project. For each composer.json, actions are invoked from its context menu in the editor or in the Project view, or using the shortcut links on top of the editor panel.

Add packages as libraries

Use this checkbox to configure the open-for-edit status of Composer packages. To protect packages under vendor/*/* against editing, leave the checkbox selected (this is the default setting).

If you want to edit the Composer packages under vendor/*/*, clear the checkbox.

Synchronize IDE settings with composer.json

Select this checkbox to automatically detect the PHP language level and configure project Source and Test roots based on the configuration from composer.json.

IntelliJ IDEA 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. IntelliJ IDEA 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.

To learn more about PSR and autoloading, refer to the Composer official website. For examples and details on synchronizing settings, refer to the PhpStorm blog post.

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.

Click this link to download composer.phar from the official storage and specify the folder to store the archive in. This instance of Composer will be available in the current project only. To use it in the command line mode, configure it as a command line tool.
