Check with Ubuntu people then, maybe there's a similar procedure.
Wikipedia seems to suggest that they also use SELinux now.

The main issue here is not what PHP is calling, it's that PHP runs  
inside your Apache webserver.
Default security policies now often prohibit the webserver to initiate  
connections to arbitrary third-party addresses and ports. By default,  
it is only allowed to answer incoming requests or use local databases.  
If you need more, you have to enable it yourself.

Try to run you PHP script from the command line, rather than the web  
environment, and you'll probably see that the database connection is  
allowed there.
If not, then just ignore this thread and look elsewhere; starting with  
enabling FreeTDS logging:
