I can not preview PHP files, what should I do?

There are two options for previewing PHP files:

• Preview using the built-in web server of the editor;
• Preview using an external web server installed on your computer.

First, make sure you have everything set up correctly:

• Click here to find out how to set up preview using external web server;
• Click here to find out how to set up preview using built-in web server.

If you still can not preview your PHP files, try turning off your Firewalls completely. Please also make sure that you do not have any application that could block or occupy TCP/IP port 89 which is the default port for the built-in web server.
