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 (refer to 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.
