PHP MSSQL（2012）提供错误：无法连接到SQL Server

Question

I am trying to fetch a set of fields from a Database on MSSQL Database on SQL Server 2012. This is a remote server and I am trying the following piece of code.

//MSSQL Server for retrieving the Member name from Member ID:

//mssql.secure_connection = On
// Need to upload ntwdblib.dll from net

$myServer = "IPAddress/SQLExpress "; // host/instance_name
$myUser = "ID"; // username
$myPass = "pass"; // paasword
$myDB = "dbname"; // database name

// connection to the database
$dbhandle = mssql_connect($myServer, $myUser,$myPass)
or die("Couldn’t connect to SQL Server on $myServer"). mssql_get_last_message();

// select a database to work with
$selected = mssql_select_db("sportsclub", $dbhandle)
or die("Couldn’t open database $myDB");

echo "You are connected to the " . $myDB . " database on the " . $myServer . ".";

$query = "SELECT first_name, last_name";
$query .= "FROM members ";
$query .= "WHERE member_id='".$row['member_id']."'"; 
 // your database query
$result = mssql_query($query);
while($row = mssql_fetch_assoc($result))
{
echo "<td>" . $rows["first_name"] . $rows["last_name"] . "</td>";
}
// close the connection
mssql_close($dbhandle);




//Ended MSSQL Connection

It simply does not connect to the sql server. It gives the error: Couldn't connect to SQL Server on IPAddress/SQLExpress

I tried checking all configurations like TCP/IP through SQL Server Config management.

Can someone please help?

Ensure remote connections over named pipes are enabled and make sure you're using a backslash before the instance name:

$myServer = "IPAddress\SQLExpress ";

If you'd like to enable connection over the default port (1433) this answer will help.
