[Skunkworks] Linux, PHP and MSSQL

I'm looking at using FreeTDS on Linux to connect PHP to Microsoft SQL Server 2000 because I'm working with a distributed system. Anyone implemented this before (with the mssql function prefix or with ODBC?), I'd like to know the pitfalls if any-the client is very big on stability. Any information about other commercial components/drivers to provide this connectivity will be highly appreciated. I don't want to have to redo the whole thing in C#. Thanks in advance. -- K. K.
