IntelliJ IDEA 2023.1 Help


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 on the Settings | Plugins page as described in Installing plugins from JetBrains repository. 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 the 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 field, specify the location of the composer.json that you want to use as default. All the Composer commands invoked from Tools | Composer from 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, and invoke Composer actions and commands for each of them.

If a project contains subdirectories with dedicated composer.json files, IntelliJ IDEA handles Composer-managed dependencies and settings for each of such modules independently. Every subdirectory with composer.json installed in it will have its own PSR-0/PSR-4 roots settings and vendor directory with External Libraries.

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 their namespace prefixes. It sets the Source root the Source root icon based on the autoload section, and the Tests root the Tests root icon based on the autoload-dev section. 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 folders exactly match the project structure, and the correct PHP language level is set automatically.

Check for available package updates

Use this checkbox to configure automatic checks for available package updates. By default, the checkbox is selected. To retrieve the available package updates and provide better coding assistance in composer.json, IntelliJ IDEA runs the update --dry-run command in the background every time you open a project or modify composer.json.

Show composer.json top panel with quick actions

Use this checkbox to toggle the visibility of the quick actions panel displayed on top of the composer.json editor. See Work with composer.json for details.

Notify about missing vendor directory

Select this checkbox to have IntelliJ IDEA check whether the vendor directory is missing and display the corresponding notification every time you open a project or modify composer.json. You can use the shortcut link in the notification to quickly install Composer dependencies.


In this area, choose how the Composer commands will be executed:

  • To run commands via a globally installed composer executable, choose 'composer' executable and specify its location in the field.

  • To run commands via the local composer.phar archive, choose composer.phar. Then, either specify the location of the existing composer.phar file in the field or select the Download composer.phar from checkbox to download a new instance of the file. The composer.phar file will be saved under the project root folder specified in the Location field.

    Then, choose one of the configured local PHP interpreters from the PHP interpreter list. Refer to Configuring Local PHP Interpreters for details.

  • To run commands via a remote interpreter, choose Remote interpreter.

    • From the CLI Interpreter list, select a remote interpreter to use, or click the Browse button and configure a new one as described in Configuring Remote PHP Interpreters.

      In most cases, IntelliJ IDEA detects path mappings automatically. If necessary, you can click the Browse button in the Path mappings field and specify them manually in the Edit Project Path Mappings that opens.

    • In the Composer executable field, provide the name of the Composer executable. You can click the Browse button, and locate the executable in the Select Path On The Server dialog that opens.
