Mysql and PHP

[SpeedySven]

I have just set up a development server running RedHat9 with Apache 2 and PHP 4.2.2 and MySQL 3.23, I have managed to get them all working individually and now have Apache running PHP, but i cannot get PHP to run MySQL, i always get the error message FATAL ERROR: Call to undefined function mysql_connect().
I believe this is because I need to have a copy of mysql.so in the /usr/lib/php4 file but the only copy of this file I can find is in a perl folder somewhere is this the right file?? or where can I get the right file from. I guess this is a pretty simple one but this is my first time on Linux as a sys admin. Cheers,
Sven

Well if you only installed MySQL from the RPM's you probably didn't install the development packages. You will need to install those as well. Then you'll need to re-compile your PHP giving it the --with-mysql=/usr/local/mysql flag (make sure the directory points to the directory above where your lib/ and include/ directories exist that hold your mysql libraries and include files, the one listed should be standard).
