Fatal error: Call to undefined function: mysql_connect()

I get the above error when I try to do a mysql_connect() from a php page. phpinfo lists mysql as "*Extensions listed here are (or will be soon) available as external modules. To install one or all of these, use "urpmi" php-EXTENSION_NAME" *when I run urpmi mysql, it asks me for a CDROM which I do not have (I downloaded it) I edited /etc/php.ini, uncommenting the lines having to do with mysql & rebooted, to no avail. Same error. Someone told me that I need to download the php source, and recompile it, but that seems too drastic - it seems to me that I've already got all the puzzle pieces, theres just a little magic configuring that needs to happen. Anyone know how to get php talking to mysql? Thanks, :-D* *
