Install IIS 7.5 PHP & FastCGI for PHP on Windows 7

Why install IIS?

Obviously you want to design web sites on your local computer and test them before uploading to your web server.


Why install FastCGI and not ISAPI?

Up until php version 5.3 most web developers using php installed ISAPI
From php version 5.3 on ISAPI is not longer supported.
The alternative is to use FastCGI
Although there are many web sites complaining about this change ISAPI works well for a website with 0-20 users,
however FastCGI runs much faster under a heavy user load and equally as well with smaller loads.


This guide has been updated and rewritten as the easiest way to successfully Configure IIS 7.5 to work with FastCGI and PHP on Windows 7 is to use

Microsoft Web Platform Installer 2.0 from


The installer does all the hard work

No more downloading PHP then configuring the php.ini file

No more going into your Internet Information Services (IIS) Manager and adding a Handler Mapping FastCGI Module

No more going into your System Properties and setting up your Environmental Variables

No more spending endless hours surfing around looking for solutions that help you get it all working (it rarely happens first time)

Microsoft have done all the hard time consuming work for a change - miracles do happen.


NOTE: This install was completed on Windows 7 Ultimate 64 bit and works for 32 bit systems.
