This code doesn't connect from within PhP-IDE but works outside the IDE.

Error: Warning: mssql_connect(): Unable to connect to server: 192.168.210.10

Environment: PhPEd 3.3.1 Build IDE on Windows XP SP1, MS SQL 2000 on Windows 2000 server.

Code:

<?php
$myServer = "192.168.210.10";
$myUser = "sa";
$myPass = "*****";
$myDB = "Northwind";
$s = @mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");
$d = @mssql_select_db($myDB, $s)
or die("Couldn't open database $myDB");

?>

It is clear, though.
Please remove @ before mssql_connect and let me see what warning is actually given.

Warning: mssql_connect(): Unable to connect to server: 192.168.210.10 in C:\Program Files\NuSphere\TechPlat\apache\htdocs\connect-sql.php on line 6
Couldn't connect to SQL Server on 192.168.210.10

I installed everything on a new machine and the code runs fine IE6 but not in the IDE. Error: Fatal error: Call to undefined function: mssql_connect() in C:\Program Files\Apache Group\Apache2\htdocs\test.php on line 6

I found it: in Tools -> Settings -> Srv web server the location for php was not c:\php.....

It would be sufficient if you took a look into phpinfo()
