PhpStorm 2020.2 Help

Composer dependency manager

PhpStorm integrates with the Composer dependency manager, which allows you to declare packages from Packagist or a custom repository as your project's dependencies and manage them from the IDE.

PhpStorm provides comprehensive coding assistance for working with composer.json as well as the dedicated user interface for running common Composer commands:

When you run the above commands, PhpStorm displays their output via the Composer Log console.

If you wish to use the full range of Composer commands in a PhpStorm project, you can configure and run Composer as an external command-line tool.

Download and install Composer

For details on installing Composer, refer to the Composer official documentation.

If you work in a local environment, Composer commands in PhpStorm are run via the configured local PHP interpreter. You can download and install Composer manually as a system-wide standalone tool, or have PhpStorm download it automatically when you create a new Composer project, initialize Composer, or invoke other Composer commands in an existing project.

Additionally, PhpStorm enables you run Composer commands via any configured remote PHP interpreter.

Manage Composer projects

In PhpStorm, you can create new projects based on the Composer package of your choice or work with existing Composer projects. PhpStorm will resolve the dependencies and use the information from composer.json to automatically apply the certain configuration options.

Create a new Composer project

When you create a new Composer project, PhpStorm creates a project based on the Composer package of your choice, resolves the dependencies and installs them under the project's vendor directory.

  1. Choose File | New Project or click Create New Project on the PhpStorm Welcome screen.

    The New Project dialog opens:

    Creating a new Composer project
  2. In the dialog, specify the project's parameters:

    • Choose the project type and location:

      • In the left-hand pane, select Composer Project.

      • In the Location field on the right-hand pane, specify the folder where the project will be created.

    • 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 getcomposer.org checkbox to download a new instance of the file. The downloaded composer.phar file will be saved under the project root folder.

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

      Optionally, in the Command line parameters field, type the additional command line parameters.

    • In the Package area, type the name of the desired package in the Package field. To use code completion, press Ctrl+Space. Then choose the relevant version from the Version to install list.

  3. Click Create. The create-project Composer command will be invoked with the selected package. As a result, the Composer project will be created, whose configuration and structure depends on the selected package. After that, the created PhpStorm project opens.

Initialize Composer in an existing project

When you initialize Composer in a project, composer.json is created. This file lists the project dependencies and other metadata and is automatically set as the project default.

  1. From the main menu, select Tools | Composer | Init Composer.

    The Composer Settings dialog opens:

    the Composer Settings dialog
  2. 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 getcomposer.org checkbox to download a new instance of the file. The downloaded composer.phar file will be saved under the project root folder.

      Then, choose one of the configured local PHP interpreters from the PHP interpreter list. Refer to Configure 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 Configure remote PHP interpreters.

        In most cases, PhpStorm 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.

  3. Click OK to close the Composer Settings dialog. PhpStorm creates a composer.json stub file and opens it in the editor:

    the composer.json file stub

    Complete the code or accept the generated values. For details on working with the composer.json file, refer to Composer.json: Project Setup.

Open an existing Composer project

When you open an existing Composer project, PhpStorm uses the information contained in the composer.json file to automatically apply the certain configuration options, for example the project's content roots and PHP language level.

  1. Click Open on the Welcome screen or choose File | Open from the main menu, then choose the folder where your Composer project is stored.

    PhpStorm will show a notification:

    ps_composer_notification_composer_json_detected.png
  2. Click Initialize Composer settings. In the Composer dialog that opens, specify the location of the composer.json file. If PhpStorm detects an existing file, the Path to composer.json field will be filled automatically:

    ps_composer_path_detected.png
  3. Configure the project settings:

    • By default, all packages under the vendor/*/* directory are excluded from the project and added as write-protected libraries. To protect them from editing, leave the Add packages as libraries checkbox selected. Otherwise, if you want to edit Composer packages under vendor/*/*, clear the Add packages as libraries checkbox.

    • Make sure the Synchronize IDE settings with composer.json checkbox is selected 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 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. 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 folders 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. To learn more about configuring content roots, see Content root.

    • To retrieve the available package updates and provide better coding assistance in composer.json, PhpStorm runs the update --dry-run command in background every time you open a project or modify composer.json. If necessary, you can disable running the command by clearing the Check for available package updates checkbox.

    Click OK to apply the specified project settings and close the dialog.

  4. Set up Composer commands execution:

    • Do one of the following:

      • In the Settings/Preferences dialog Ctrl+Alt+S, go to Languages and Frameworks | PHP | Composer.

      • If you have a single composer.json file in your project, select Tools | Composer | Install from the main menu to open the Composer Settings dialog.

    • 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 getcomposer.org checkbox to download a new instance of the file. The downloaded composer.phar file will be saved under the project root folder.

        Then, choose one of the configured local PHP interpreters from the PHP interpreter list. Refer to Configure 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 Configure remote PHP interpreters.

          In most cases, PhpStorm 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.

  5. Install the project dependencies:

    • If you have a single composer.json file in your project, select Tools | Composer | Install from the main menu.

    • Otherwise, if you have several composer.json files, select Composer | Install from the context menu of the relevant one. See also Appointing a default composer.json in a PhpStorm project.

    You can also open the composer.json file in the editor and click the Install shortcut link on top of the editor panel.

Appoint a project default composer.json

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, or using the shortcut links on top of the editor panel. You can also appoint the default composer.json for your PhpStorm project. Composer actions for it are invoked from the Tools | Composer main menu item.

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Languages and Frameworks | PHP | Composer.

  2. Specify the location of the default composer.json. If you have a single Composer configuration file in your PhpStorm project, the Path to composer.json field is filled automatically.

  3. By default, all packages under the vendor/*/* directory are excluded from the project and added as write-protected libraries. To protect them from editing, leave the Add packages as libraries checkbox selected.

    Otherwise, if you want to edit Composer packages under vendor/*/*, clear the Add packages as libraries checkbox.

  4. Make sure the Synchronize IDE settings with composer.json checkbox is selected 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 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. 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 folders 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. To learn more about configuring content roots, see Content root.

Work with composer.json

The composer.json file describes the dependencies of your project and may also contain other metadata. PhpStorm provides comprehensive coding assistance for working with composer.json and lets you perform many Composer-related tasks directly from the code editor.

Create a composer.json file

You can create composer.json files manually. If Composer hasn't yet been initialized in the project, a newly created composer.json will be automatically set as the project default.

  1. Do one of the following:
    • In the Project tool window Alt+1, select the directory in which you want to create a new file, and then choose File | New from the main menu.

    • Right-click the corresponding directory and select New from the context menu.

    • Press Alt+Insert.

  2. In the popup menu, select composer.json File. PhpStorm creates a stub of the composer.json file and opens it in the editor.

Use code completion in composer.json

  • Inside composer.json, press Ctrl+Space to use code completion when providing both the names of the sections and their content, for example:

    • License type and minimum-stability version,

    • Namespaces and paths in the autoload and autoload-dev sections,

    • Required PHP version and extensions as well as packages' names and versions in the require and require-dev sections.

    Code completion in composer.json

Use quick documentation in composer.json

  • Inside composer.json, press Ctrl+Q to view quick documentation for the element at caret.

    Viewing quick documentation for a Composer package

Navigate from a composer.json record to the project entity or setting

  • Inside composer.json, position the caret at an entity such as an installed package, a class or a method within a script, a file path, or a url. Then do any of the following:

    • In the main menu, select Navigate | Declaration or Usages

    • Press Ctrl+B

    Alternatively, Ctrl+Click the record.

    Code navigation in composer.json
  • If you have a test framework or code quality tool installed as a project dependency, PhpStorm displays the Settings/Preferences button next to the corresponding dependency record. Click it to jump directly to the corresponding Settings/Preferences page.

    the Open Settings button in the gutter of composer.json

    For details on using test frameworks, see Testing; for details on working with code quality tools, see and PHP Code Quality Tools.

Manage dependencies

To install, update, or uninstall project dependencies, you need to update the records in the require or require-dev sections in composer.json and then run the corresponding Composer command.

To retrieve the available package updates and provide better coding assistance in composer.json, PhpStorm runs the update --dry-run command in background every time you open a project or modify composer.json. If necessary, you can disable running the command. In the Settings/Preferences dialog Ctrl+Alt+S, go to Languages & Frameworks | PHP | Composer and clear the Check for available package updates checkbox.

Install dependencies

  1. Inside composer.json, add the desired dependency record to the require or require-dev section. Press Ctrl+Space to get code completion both for the package name and version.

    Adding a dependency in composer.json
  2. Do one of the following:

    • Click the Install shortcut link on top of the editor panel.

    • If the Non-installed Composer packages inspection is enabled, PhpStorm will highlight the declared dependencies that are not currently installed. Press Alt+Enter and select whether you want to install a specific dependency or all dependencies at once.

      Install a package via the quick-fix

When a new package is installed, PhpStorm creates a new subfolder under vendor and stores the package inside. If the composer.lock file. present in the current directory, the exact packages versions listed in it are installed. Otherwise, if the composer.lock file is missing, Composer will create it after installing the packages, thus locking your project to their specific versions.

Update dependencies

You can update packages to their latest versions individually, or update all the packages listed in the require and require-dev sections of composer.json at once.

  • When a new package version is available or the package versions requirements change, PhpStorm indicates this via the the Update Package button icon in the editor gutter. It also provides the hint on the currently installed version and the version the package can be updated to.

    Click the Update Package button to update the package.

    Package update is available
  • To update all packages, click the Update shortcut link on top of the composer.json editor panel.

Uninstall dependencies

  1. Remove the package record from the require or require-dev section of composer.json.

  2. Click the Update shortcut link on top of the composer.json editor panel.

Use a custom package repository

Besides Packagist, you can use a custom package repository.

  • Inside composer.json, create a repositories section for your repository:

    { "name": "vendor_name/package_name", "repositories": [ { "type": "composer", "url": "http://packages.example.com" } ] }

    After PhpStorm retrieves the packages information, you can install, update, and uninstall packages as usual.

Create and run Composer scripts

With Composer, you can create and run scripts, which are used for executing some custom code or package-specific commands during the Composer execution process.

Define a Composer script

  • Inside the scripts section of composer.json, create an event property, and list the desired scripts inside it. Each script can be a PHP callback defined as a static method, a command-line executable command, or a reference to an existing script.

    Use code completion Ctrl+Space to get suggestions for event names, classes' and static methods' names, and binaries installed under vendor/bin. To add a reference to an existing script, prepend it with the @ symbol.

    Create a Composer script

Rename a Composer script

  1. Position the caret at a script's definition or usage.

  2. Invoke the Rename refactoring by selecting Refactor | Rename from the main menu or from the context menu, or press Shift+F6.

  3. In the Rename dialog that opens, provide the desired name for a script.

    Rename a Composer script
  4. Click Preview to observe possible changes in the Find tool window. Click Refactor to proceed.

Run a composer script

  • Click The Run button in the gutter next to the script you want to execute. From the list, select Run <script name>.

  • Right-click inside the script you want to run and select Run <script name> from the context menu.

  • Position the caret at the script you want to execute, press Alt+Enter and select the Run <script name> intention action.

    the Run Composer Script intention action

When the script is executed, PhpStorm automatically creates a dedicated temporary Composer Script run/debug configuration for it. You can save it as a permanent run/debug configuration if necessary.

Create a Composer script run/debug configuration

You can execute Composer scripts by using run configurations of the Composer Script type. With the run configuration, you can execute a script at any point, add it to the Services tool window, or a compound configuration. Refer to Working with Run/Debug Configurations for details.

  1. Do any of the following:

    • In the editor, right-click inside the desired script record and select Create <configuration name> from the context menu.

      Create a run configuration from the editor
    • Alternatively, choose Run | Edit Configurations from the main menu, then click Add icon and choose Composer Script from the list.

      Add new Composer Script run configuration
  2. Provide the run/debug configuration parameters:

    • Path to composer.json: in this field, provide the path to composer.json that contains the desired script's definition.

    • Script: from this list, select one of the defined Composer scripts to execute.

    • Command line parameters: in this field, type the additional command line parameters. These parameters will be passed as CLI arguments to the CLI handlers; inside PHP handlers, they can be retrieved as an array via $event->getArguments() calls.

Save a temporary Composer Script run/debug configuration

When you execute a Composer script from the editor, PhpStorm automatically creates a temporary run/debug configuration with the script parameters. A temporary run/debug configuration works the same way as a permanent run/debug configuration. You can change its settings using the Run/Debug Configuration dialog and optionally save it as permanent.

  • In the Run/Debug Configuration selector, choose Save <configuration name>.

    Save a temporary run configuration
  • In the Run/Debug Configuration dialog, select the configuration and click the Save button.

Click the Settings button in the gutter it to quickly navigate to the corresponding Directories, PHP, Test Frameworks, or PHP command line tools settings pages.

Run additional Composer commands

PhpStorm provides the user interface for a set of additional Composer commands.

  • From the composer.json context menu, select Composer | <command name>.

  • Open composer.json in the editor, click the Settings button on top of the composer.json editor panel, and choose the desired command from the list.

  • To run a command for the default composer.json, select Tools | Composer | <command name> from the main menu.

If Composer execution is not set up, the Composer Settings dialog will open, prompting you to 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 getcomposer.org checkbox to download a new instance of the file. The downloaded composer.phar file will be saved under the project root folder.

    Then, choose one of the configured local PHP interpreters from the PHP interpreter list. Refer to Configure 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 Configure remote PHP interpreters.

      In most cases, PhpStorm 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.

Validate

Run this command to perform several validity checks against the composer.json file, which is recommended before committing composer.json to a VCS. Validation results are displayed in the Composer Log console.

The equivalent %tool% CLI command is validate.

Before executing the command, choose the desired options in the Validation Settings dialog:

  • Allow unbound version constrains: If selected, version constraints without an upper bound (for example *, >3.1) will be permitted. Note that this will allow updates to any future version of a dependency, which may cause backward compatibility issues in the case of unexpected changes in dependencies.

    The equivalent option of the %tool% CLI command is --no-check-all.

  • Check if composer.lock is up-to-date: If selected, the version constraints listed in composer.lock will be checked against the ones listed in composer.json. If the version constraints do not match, it is recommended to fix this by updating packages. After the packages are updated to the required versions, the composer.lock and the composer.json files will be synchronized.

    The equivalent option of the %tool% CLI command is --no-check-lock.

  • Check if the package is Packagist-ready: If selected, the package's composer.json will be checked against the Packagist publishing requirements. Generally, for a package to be Packagist-ready, the name, description, and require sections in its composer.json file must be specified. Refer to the Packagist documentation for details on publishing packages.

    The equivalent option of the %tool% CLI command is --no-check-publish.

  • Validate package dependencies: If selected, the composer.json files of all installed dependencies of the current package will also be validated.

    The equivalent option of the %tool% CLI command is --with-dependencies.

Dump Autoloader

Run this command to generate the list of autoloaded classes. If the list already exists, it will be generated anew. This can be useful in situations when you introduce a new class in a project and need to include it to the list of autoloaded classes. Refer to the Composer documentation for more details on autoloading classes with Composer.

The equivalent %tool% CLI command is dump-autoload.

Before executing the command, choose the desired options in the Autoloader Generation Settings dialog:

  • Skip scripts execution: If selected, the scripts defined in the scripts section of the composer.json file are not executed.

    The equivalent option of the %tool% CLI command is --no-scripts.

  • Optimize autoloader (Convert PSR-0/4 autoloader to a classmap): If selected, Composer will scan the given PSR-0/4 autoloading directories/files for the php and inc files and generate a single autoload_classmap key-value array to speed up autoloading. Note that if the number of classes is large, running this command can be time-consuming.

    The equivalent option of the %tool% CLI command is --optimize.

  • Autoload classes from the classmap only: If selected, only the classes listed in the class map will be autoloaded. Composer will not search for fallback PSR-4 directories for classes not listed in the class map. Since this naturally requires an existing class map, Composer will also execute the Optimize autoloader (Convert PSR-0/4 autoloader to a classmap) command to generate one, which can be a time-consuming process.

    The equivalent option of the %tool% CLI command is --classmap-authoritative.

  • Use APCu for caching found/not-found classes: If selected, caching via APCu will be enabled. When a class is found (or not found) in the class map, the corresponding record will be cached in APCu, so that it can be quickly retrieved on the next request.

    The equivalent option of the %tool% CLI command is --apcu.

  • Disable autoload-dev dependencies: If selected, the autoloaded namespaces and files listed in the autoload-dev section are not included into the autoloaded classes list.

    The equivalent option of the %tool% CLI command is --no-dev.

Check for Changes in Dependencies

Run this command to check if you have any local changes in the code of the package dependencies.

The equivalent %tool% CLI command is status.

Clear Cache

Run this command to delete the Composer's cache directory, which contains the downloaded packages. By default, the cache directory is set to C:\Users\<user>\AppData\Local\Composer on Windows, and to ~/.composer/cache on Linux and macOS. Refer to the Composer documentation for details.

The equivalent %tool% CLI command is clear-cache.

List Licenses

Run this command to view the name, version, and license type of every installed package.

The equivalent %tool% CLI command is licenses.

Diagnose

Run this command to perform automated checks for the most common Composer problems (for example connectivity issues, Composer/PHP version used, disk space available, composer.json validity). If the problem is not identified, refer to the Composer troubleshooting guide.

The equivalent %tool% CLI command is diagnose.

Simulate Update

Run this command to simulate updating the dependencies without actually running composer update. In doing so, you can verify whether all dependencies are resolved successfully and preview the changes while keeping everything intact.

The equivalent %tool% CLI command is update --dry-run.

To retrieve the available package updates and provide better coding assistance in composer.json, PhpStorm runs the update --dry-run command in background every time you open a project or modify composer.json. If necessary, you can disable running the command. In the Settings/Preferences dialog Ctrl+Alt+S, go to Languages & Frameworks | PHP | Composer and clear the Check for available package updates checkbox.

Self-Update

Run this command to update Composer itself (that is, the composer.phar file) to the latest version.

The equivalent %tool% CLI command is self-update.

Run Composer from the command line

Command-line mode provides you with the full range of Composer commands. To use Composer in this mode, you need to configure it as an external command-line tool. For details on working with command-line tools, refer to PHP command line tools.

You can have several instances of Composer configured and switch between them from one project to another by specifying the relevant one during Composer initialization.

Configure Composer as a command line tool

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Tools | Command Line Tool Support.

  2. Click the Add button on the toolbar.

  3. In the Command Line Tools dialog, choose Composer from the list, and specify its visibility level (Project or Global).

    the Command Line Tools dialog
  4. When you click OK, the dialog opens.

    Specify how you want to launch Composer by choose one of the options: composer.phar or php script or composer executable. Depending on your choice, specify the paths to the PHP installation folder and composer.phar or to the composer executable file.

    When the file analysis is completed, PhpStorm returns to the Command Line Tools Support page where the specified file is added to the list of command line tools available in PhpStorm.

  5. Click OK to apply changes and return to the Command Line Tool Support page. Optionally, click the Edit button to edit the tool properties, or the Edit Source button to customize the commands set. See Customize a tool for details.

Run a Composer command

  • From the main menu, choose Tools | Run Command or press Ctrl twice.

    In the Run Anything window that opens, type the call of the command in the <c> <command> format.

    The command execution result is displayed in the Run tool window.
