php apache module

I'm currently trying to install php3, but only have guidelines for installing php4. php seemed to install correctly with the -with-mysql option (that's the reason i'm re compiling it - to recognise mysql functions). However I think the problem is when i'm reconfiguring apache: I'm told to use ./configure -prefix=/www -activate-module=src/modules/php4/libphp4.a Does anyone know the php3 version of this php module that apache is supposed to include? thanks for your help...
