Please note that mssql_pconnect creates a connection for the pool for *each process*. If you have "ThreadsPerChild" set to 50 in apache, and mssql.max_procs set to 25 in php, then eventually you will get mssql_pconnect failing to give you a connection to the database. This has stumped me for quite a while, and the answer finally presented itself thanks to the people in #php.

If you are running PHP/Apache combination on a Windows machine that is part of a domain, using NT Authentication to connect to a MS SQL Server, you must to do the following things: 1) Turn NT Authentication On (under MSSQL in php.ini) 2) Configure the Apache service to run as the user that is authorized to access the MS SQL server. Hope this helps save someone the time that it took me to track down!

Be careful with pconnect! Platform: RH Linux 7.3, PHP 4.2.1. FreeTDS. pconnect does give you better time than connect (about 0.25-0.4 seconds gain) BUT: - occasionally, I've experienced "quirks" when fetch() would randomly return empty recordsets from stored procedurest that can_not return empty recordsets by definition. - if you restart MSSQL server while some of the connections did not time out, next pconnect() will not establish a new connection! It will return an old one, so next time you do execute() or query() your script will just _hang_ until timeouted by Apache. All of the above I believe are FreeTDS problems, not PHP. I wonder if somebody with PHP+Sybase lib got pconnect to work.
