Sqlsrv_connect() error

Question

I'm trying to connect PHP 5.3.5 to MS Sql Server 2005. I'm using Windows XP SP3. I enabled the sqlsrv function which is also shown in phpinfo(). I also made some changes in the php.ini extension but I keep getting following error:

"Database connection errorArray ( [0] => Array ( [0] => IMSSP [SQLSTATE] => IMSSP [1] => -49 [code] => -49 [2] => This extension requires either the Microsoft SQL Server 2008 Native Client (SP1 or later) or the Microsoft SQL Server 2008 R2 Native Client ODBC Driver to communicate with SQL Server. Neither of those ODBC Drivers are currently installed. Access the following URL to download the Microsoft SQL Server 2008 R2 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712 [message] => This extension requires either the Microsoft SQL Server 2008 Native Client (SP1 or later) or the Microsoft SQL Server 2008 R2 Native Client ODBC Driver to communicate with SQL Server.

I've installed sqlncli.msi , SQLSRV20.exe and SQLSRV30.exe but I'm still getting the same error.

My program to connect:

<?php
$server = "Patrik/SQLEXPRESS";
$conInfo = array("Database"=>"ShoppingDetail","UID"=>"Pat1890","PWD"=>"Pat1890");

$con = sqlsrv_connect($server,$conInfo);

if($con==false)
 {
  echo "Error Connecting to database<br>";
   die (print_r(sqlsrv_errors()));
  }
else
{
  echo "Database connection is sucessfully eastablished";
}
?> 

I think there is no problem in my coding. I also enabled TCP/IP and used the IP address instead of servername but the problem still persists.

Fisrt verify, in php.ini

extension=php_pdo_mssql.dll

and

extension=php_pdo_odbc.dll

and try with PDO

$server = 'host';
$database = 'database';
$username = 'username';
$password = 'password';
$db = new PDO('odbc:Driver={SQL Server}; Server=' . $server . '; Database=' . $database . '; Uid=' . $username . '; Pwd=' . $password . ';');
$query = $db->prepare('...');
$query->execute();

To use the sqlsrv_* functions, add extension=php_sqlsrv_X_Y.dll to your php.ini, where X represents your PHP version (53 in your case) and Y is either ts or nts for whether you installed the thread-safe/non-thread-safe build of PHP. Those DLLs should all be in your PHP install's ext folder.
