如何从PHP连接到mssql？

Question

I have a dedicated centos server. It needs to be able to connect to a remote windows machine running SQL Server 2012. The provider installed freetds. I'm running PHP Version 5.3.28.

We can ping the remote ms-sql server from the linux box. But, when I try to run the test command: tsql -S your.server.name -p 1433 -U -P it times out.

I tried the sample code I found online to test via php, but as my version is greater than 5.3 the mssql_connect function no longer is functional.

$conn = mssql_connect("servername", "<user>", "<password>");

I get Call to undefined function mssql_connect()...so, I'll have to use PDO (I think).

Anyway, the PDO probably won't work until we get the tsql to work, and it just times out.

Any ideas?

Answer 1

There are a few comments in the mssql_connect section of the php manual. Various people having had similar problems with connecting from linux/unix.

Maybe there is some insight there: http://www.php.net/manual/en/function.mssql-connect.php

Also, as always, make sure you have physical connectivity from the box itsself and from within php.

Answer 2

First of all be sure that nothing block the port 1433.

Try to run thd command:

telnet yourserver.com 1433

If you get enter - try to check configuration of the driver and configuration of mssql server.
