MySQL Database Replication Class

I have several commercial projects running on multiple servers. These servers run MySQL replication. The problem with replication is that inserts and updates can only be run on the master server. I wrote this little database class to detect when it was connected to a 'slave' server, and if a modification query was being run, to connect to the master and run it there.
