Connection Error

When I try to add an entry, I receive the following error:

MySQL Error : Connection Error
Error Number: 2002 Can't connect to local MySQL server through socket '/tmp/mysql.sock' (46)
Date : Tue, August 22, 2006 17:24:06

What am I missing? PhP is very new to me, and I don't know /whatwhere the 'tmp/mysql.sock' file is, or should be. Any help would be great.

This indicates a problem on the server and nothing you can fix.
