PHP development support is provided through the PHP plugin. The PHP plugin is not bundled with IntelliJ IDEA, but it can be installed on the Settings | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains repository.

This part describes some procedures that are specific for developing PHP applications and some preliminary steps that are required to configure PHP development environment.

Install the PHP plugin

This functionality relies on the PHP plugin, which you need to install and enable.

  1. Press Ctrl+Alt+S to open the IDE settings and select Plugins.

  2. Open the Marketplace tab, find the PHP plugin, and click Install (restart the IDE if prompted).

To develop an application using PHP

Follow these general steps:

  1. Configure the PHP development environment.

  2. Configure PHP interpreters as described in Configuring Local PHP Interpreters and Configuring Remote PHP Interpreters.

  3. Start creating a project from scratch. On the first page of the New Project wizard, choose PHP in the left-hand pane, then choose PHP Empty Project in the right-hand pane.

  4. Create and configure the required data sources (see Manage data sources).

  5. Populate the application using provided coding assistance.

  6. Deploy the application.

  7. Run the application. You can do it in several ways:

    • From IntelliJ IDEA using a run configuration of the type PHP Web Page to view application output in a browser.

    • From IntelliJ IDEA using a PHP Script run configuration to view the application output in the Run tool window.

    • From IntelliJ IDEA, using a built-in Web server. This approach saves your time and effort because you do not need to deploy the application sources.
