Question about Php/Mysql. Unsure if it's enabled.

Hello, my subject is a bit confusing, I bet. I need a bit more speace to explain this situation. Ok, basically I only configured php with apxs However, I noticed the mysql was supported (It said so on php info page) How is that possible? I never tested a mysql script yet on this server (linux) yet, I just had to ask if this is normal and how this is possible. Or if I am misinterpreting the output. The file actually prints: mysql MySQL Support enabled Active Persistent Links 0 Active Links 0 Client API version 3.23.32 MYSQL_INCLUDE MYSQL_LFLAGS MYSQL_LIBS Does this mean it really supports it? or am I just not understanding something? It even says zend server is in use, yet I never installed zend. The version of php is 4.0.5 on apache webserver on linux How is this possible? Just curious Thanks
