PHP connect to SQL?

Hey guys,

My firm has just finished a site and we are now working on the admin portion of an area of the site. Having initially been told that the site was going to be hosted on a WIN 2003 server running IIS/SQL – which is our area of proficiency – we estimated the project accordingly.

Now the client has told me that the WIN 2003 is the EVENTUAL destination but that they would like the admin and site to run and reside on their current server, which is a Netscape server that would run PHP but still connect to a SQL database, not MySQL.

I didn’t even know that it was possible to connect PHP to SQL. Do you guys have any experience in this? How would I do it?
