A couple of months ago, I wrote a quick and dirty entry on how to install PHP on IIS7. The main purpose of that entry was to explain the details of what was going on as well as cookie-cutter instructions of one way to successfully install PHP on IIS7.

Well, the responses that I have received from that blog entry made me realize that I need to provide something a little more shrink-wapped which does a few more things other than just run the bare minimum... because I was seeing way too many broken custom modifications coming from mistaken assumptions about PHP or IIS7.

Here it is, V2. Just copy/paste the following into a .bat file, right-click run it as elevated Administrator on Vista, and follow the prompted instructions. You should have PHP extracted into a directory of your choice before-hand (I favor and default to %SYSTEMDRIVE%\Inetpub\PHP for many aforementioned reasons; in my examples, I chose "C:\Program Files\P H P" to show it working with long pathnames).

The batch script:

  • Works with PHP installed wherever, including pathnames with spaces. Just tell it where you installed PHP (sans double quotes and trailing backslash)
  • Gives choice of whether to use the CGI or ISAPI version of PHP. You do have to give the correct binary name (php5isapi.dll or php-cgi.exe, assuming PHP5), but there are checks for that
  • Gives warnings and errors if the directory/file does not exist, mismatched binary types, and additional steps you need to do to have a minimally functioning PHP

Now, I am no PHP expert, so I can only give instructions for how to get PHP configured and running on IIS7. Questions about all other PHP-related features (like PHP extensions, integration with mySQL, etc) and how to get them working really belong on a PHP support forum.

Sample Execution Results:

  • Setting up PHP5 installed at "C:\Program Files\P H P", ISAPI version. Notice the defaults and verification of provided inputs.
