Thanks for the replys, I managed to fix my problem. I wound up formatting (for reasons other than this, of course), and reinstalled PHP via the executable. Then I just took the entire binary and pasted it into the C:\PHP folder. I realize I could have just installed the binary on it's own, but I wasn't thinking when I installed the executable, and decided to try it that way. It works now, at least, I'm able to connect to mssql. Actually doing anything with mssql is a whole nother hurdle. But thanks again.
