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 that should be installed and enabled in your IDE.
The plugin is available only in IntelliJ IDEA Ultimate.
Press Ctrl+Alt+S to open the IDE settings and select.
Switch to the Marketplace tab and use the search field to find the PHP plugin.
Click Install and restart the IDE if prompted.
To develop an application using PHP
Follow these general steps:
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.
Create and configure the required data sources (see Manage data sources).
Populate the application using provided coding assistance.
Deploy the application.
Run the application. You can do it in several ways:
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.
The following optional steps may be helpful:
Set up unit testing in your project.
Debug the application.
