Which web server am I on?

[actionsnaps]

I searched and cannot find the answer. I am putting together a Simple Veiwer photo gallery and it asks the following: (which do I select?)

""""Select which server-side script to use based on your webserver type. Unzip Build script into the same folder created in Step 1.

* Download PHP version (zip file - 3k). For Unix web servers (if you don't know which type of server you have, try this one first).
* Download ASP .NET version (zip file - 3k). For Microsoft servers.
* Download ASP classic version (zip file - 1k). For Microsoft servers without .NET. (this version does not generate thumbnails.)
* Download ColdFusion version (zip file - 3k). For servers with ColdFusion installed. (this version does not generate thumbnails.)
* Download Perl version (zip file - 3k). For servers with Perl installed.""""

PHP or Perl - either one will work - PHP may have more people here to help out if you get in a snag.
