ใช้ Web Server บน Linux Server แล้วจะติดต่อฐานข้อมูล Microsoft® SQL Server 2008 จะต้องทำอย่างไร

<?php
$myServer = "192.168.0.8\SQLEXPRESS";
$myUser = "use";
$myPass = "pss";
$myDB = "erpdb";

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

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

//declare the SQL statement that will query the database
$query = "SELECT * FROM erpbusiness ";

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result);
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";

//display the results
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["COMNO"] . $row["COMNAME"] .  "</li>";
}
//close the connection
mssql_close($dbhandle);

?>
