Connecting remote SQL Server to PHP - php

Question

Can any one explain the connection string from the parameters below:
server IP : 192.168.137.4
Windows Authentication : Windows Authentication
UserName : DELL-M102Z\dell
Database : DataProd
Network Protocol : <default>
Product Name : Microsoft SQL Server Express Edition
Server Name : DELL-M102Z\SQLEXPRESS
Instance Name : SQLEXPRESS
Computer Name : DELL-M102Z
I tried:
$serverName = "DELL-M102Z\SQLEXPRESS"; //serverName\instanceName
$username = "DELL-M102Z\dell"; //serverName\instanceName
$conn = mssql_connect( $serverName,$username,'');
...but the result I got was:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: DELL-M102Z\SQLEXPRESS in C:...\index.php on line 17
Connection could not be established.
Can anyone tell me what is the problem here?

<?php
$myServer = 'xxx.xxx.xxx.xxx:yyyy';
$myUser = 'sa';
$myPass = 'xxxxx';
$con = mssql_connect($myServer, $myUser, $myPass) or die("Could not connect to database: ".mssql_get_last_message());
if($con){
echo "connected";
}
// Select a database:
mssql_select_db('new')
or die('Could not select a database.');
// Example query: (TOP 10 equal LIMIT 0,10 in MySQL)
$SQL = "SELECT TOP 10 * FROM Table";
// Execute query:
$result = mssql_query($SQL)
or die('A error occured: ' . mysql_error());
// Get result count:
$count = mssql_num_rows($result);
print "Showing $count rows:<hr/>\n\n";
// Fetch rows:
while ($Row = mssql_fetch_assoc($result)) {
print $Row['BillNo'] . "\n";
}
mssql_close($con);
$myServer = 'IP_Address:PORT';
Here semicolon is need to ip and port
and
Mssql is enbaled at your cpanel
