Following the previous messages, my situation resumes in something like this. The Extension must be properly installed because the file appears in the correct path, so it must be something missing in the apache configuration file ('httpd.conf') or in the php inicialization file ('php.ini'). Could someone please describe me every step i need to take and everything i need to change in this files when i'm installing a php extension for the first time and assuming that the php.ini is actually the native php inicialization file on Leopard ('php.ini.default'), i think that maybe a little especific "crash-course" can solve all my problems. Someone please... Regards Rui Quelhas
