Need to access a MSSQL database from php on Linux? The remi repository has php-mssql and all the dependencies.  Look for the yum configuration link on the home page.  Very easy.

They also have a link to an IT asset management program called GPLI, I haven’t used it but the demo looks pretty nice.  The functionality seems to be there, but interface could use a little polishing, IMHO.
