Connecting to MSSQL server via php-pdo?

问题

I'm unable to connect to MSSQL database on smarterasp.net domain. I'm using:

PHP Tools for Visual Studio

Here is the code:

<?php
 try {
     $conn = new PDO("mssql:host=host_name_string;dbname=database_name_string", "username_string", "password_string");

     // set the PDO error mode to exception
     $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
     echo "Connected successfully"; 
 }
 catch(PDOException $e)
 {
     echo "Connection failed: " . $e->getMessage();
 }

?>

and the error caught by the PDOexception class:

Connection failed: could not find driver

I've also tested my code online and again getting the same error(online tester url: http://sandbox.onlinephpfunctions.com).

I've searched for the solution and the only thing that could resolve my problem is by uncommenting:

extension=php_pdo_mysql.dll

but the line is already uncommented by default.

EDIT: The following does not ressolve my problem (instead of mssql:host)

• sqlsrv:host
• dblib:host

Your problem is that you have not installed either the sql server client or the Microsoft pdo drivers on your machine. Please do that and make sure you can connect via a udp file.

Search SQL server client install and Microsoft pdo drivers
