mssql 7.0 -- PHP 4 connection

hi there, I was wondering what I needed to install in order to enable the mssql_ commands (which are listed in the PHP manual at www.php.net/manual). Will installing the sybaseCT OpenClient module do the trick? I'm running PHP 4 Beta as an Apache 1.3.6 module under Red Hat Linux 6.0. I need to connect to a SQL Server 7.0 database (which naturally resides on a separate NT machine). Is there any issue with PHP 4 connecting to SQL 7.0? I've read several articles in one of the mailing list archives suggesting that it is very difficult to get PHP 3 to connect to SQL 7.0... Currently, when I try to run PHP scripts incorporating, for example, mssql_connect(), the script breaks with a "fatal error: mssql_connect() undefined" error message. I'm obviously missing something... Thanks for any help, and sorry for the stupid questions... =( Alex K. alex@mailbank.com
