If you get an error stating that you don't have support for MySQL functions, then you need the MySQL library (.dll for winblows, .so for UNIX/Linux). I think the DLL comes with the windows distro. As for linux, the easiest way is to get an RPM of php-3.X-mysql-i386.rpm. This has the mysql.so file in it, and is precompiled for Intel-Linux. You will need to relocate (--relocate) the file paths in the RPM command, otherwise, it'll check the dependancies and say you don't have the right version. Anyway, once you've gotten the mysql.so file out of the RPM, just copy it to the PHP shared-files directory (might be the same as Apache, but you can check in the php.ini/php.cfg file). Alternatively, you can search for a DSO file (.so) that you know you have and put the mysql.so with it.
