I am trying to configure PHP5 on my server to interact with my MySQL database. Unfortunately, the person who configured PHP5 before me did not include the MySQL support. So when I try and connect to my database through php, I get the "Fatal Error: Cannot connect to MySQL fucntion()".

Without reinstalling PHP5, how can I simply add the MySQL packages to my current PHP5 configuration? If it's not simple, what's the hard way?

Thank you for your time,
