$rows = mssql_fetch_array($results);

If you use sql server, use this code. This works for me:
<?php
$serverName = "serverName";
$options = array( "UID" => "sa", "PWD" => "Password", "Database" => "DBname");
$conn = sqlsrv_connect($serverName, $options);
if( $conn ) {
echo "Connection established.<br />";
$query="select * from SubscriberServices where SubscriptionGroupID like 'ms_gp_tr24bn_3333'";
$result = sqlsrv_query($conn,$query);
sqlsrv_close($conn);
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
?>
if it returns "Connection established." it's mean you install MS SQL Drivers correct.
