This article will walk you through installing PHP on IIS 7.0. Please note that this article only addresses the actual install of PHP using the FastCGI protocol. For more information on FastCGI, see the official Microsoft IIS site here.

• Here we'll check CGI under Application Development (click Next - Install - Close to finish)

• Once added, it's important that we update the FastCGI module. Click on one of the following links:

Windows Server 2008 x86

Windows Server 2008 x64

• Once you've verified PHP is installed, we'll want to test it out. To do this, open up notepad and enter the following:

<?php phpinfo(); ?>

• Save this new file as phpinfo.php in your websites default directory

• Now browse to localhost/phpinfo.php If everything is set up correctly, you will see something similar to the following:

Congratulations, you have successfully installed PHP in IIS!
