With IIS, if you're having errors with PHP functions working, the first thing I'd check is that you're using the appropriate functions for your version of PHP. Example, certain functions no longer exist in PHP 5 and some have been added. Another thing I'd try is editing the php.ini file in your windows directory for IIS (I think it's probably in a subfolder, but I haven't done this one in a while) and enable the errors and warnings. That'll tell you anything you need to know - and unfortunately more - about why your code isn't working.
