มีปัญหา PHP 5.5.11 เชื่อมต่อกับ SQL Server 2008 ไม่ได้ครับ

<?

   $serverName = "tcp:bc6hela9fr.database.windows.net,1433";
   $userName = 'thaicreate-user@bc6hela9fr';
   $userPassword = 'password@123';
   $dbName = "thaicreate-db";

   $conn = new PDO("sqlsrv:server=$serverName ; Database = $dbName", $userName, $userPassword);

   $strSQL = "SELECT * FROM customer";

	$stmt = $conn->prepare($strSQL);
	$stmt->execute();
