I am indeed on WinScrap98 for development purposes :
php 4.0.1pl2 for win32 (cgi mode)
apache 1.3.12 for win32
mysql 3.23.x for win32
although the link seemed strange, the scripted still worked anyway though, even if it bothers me that the php_self var didn't return only the filename instead of teh full (virtual) path
