php / mssql connection problem

Hi,

I'm trying to connect to one of our database installed on a new MSSQL 2008 server and I can't get the connection. It always stop on "couldn't connect to SQL Server". The MSSQL 2008 has the named pipes set to yes and I can reach the server through ODBC connection as well as through the SQL studio management on another computer.

Is it a way to check why we're rejected in some logs somewhere? The webpage is running under a Suse server
<?php
   $MSBIZ_connection = "servername" ;
   $MSBIZ_username = "username" ;
   $MSBIZ_password = "pwd" ;
   $MSBIZ_name = "Prod";

   $sqlconnect = mssql_connect($MSBIZ_connection, $MSBIZ_username, $MSBIZ_password)
	or die("Couldn't connect to SQL Server on [" . $MSBIZ_connection . "]");

   $selected = mssql_select_db($MSBIZ_name, $sqlconnect)
	or die("Couldn't open database [" . $MSBIZ_name . "]"); 

?>

My first suggestion would be to use the odbc function

http://uk3.php.net/manual/en/function.odbc-connect.php

Otherwise, have you made sure the MSSQL extension is enabled by adding

extension=php_mssql.dll

to your php.ini. (Because the default setting  is not enabled).

Hi,

thanks for your suggestions...

- the TCP/IP is already on.

- the mssql is available as it was working before we change the database. When I do the php -m, it appears as module loaded.

any other ideas?

Your version of ntwdblib.dll may need updating.

You can download the latest version via this page

Hi

thanks for your answer but as mentioned in your link, it's to update the file in the server hosting the PHP. But our php server runs under linux, do you know if that kind of file may exists for linux? shall I update maybe our php version?

ntwdblib.dll - The most common issue is that you do not have the ntwdblib.dll file installed in your PHP directory (where php.exe is, or sometimes placing it in the ext directory works as well). This library can be found with your Enterprise Manager dll's or in your SQL servers system32 folder. It's generally best to take the file from the server where SQL Server is installed.

Hi

Forget my last post about updating the linux php. I've tried on another of our server using a recent version of php and IIS and the problem was the same. But we tried to connect to another SQL server with a differente database and we manage to connect without any problems....

could it be a problem of version, hotfix or anything else??? does it sounds familiar to anyone?

A bit of googling and it looks like the only ways to do it are FreeTDS or ODBC.

Never done it myself. Ubuntu does a virtual package of PHP5-mssql which uses the sybase package, this seems to be the most well documented root.
