php mysql querys work in Xampp but not my LAMP Stack in AWS cloud

this is just a test case I wrote but my main question is my whole application works locally connect to MySQL and return a couple thousand records I turn error reporting on EALL forthe page and I don't get any error all I actual get for output of this test case is Number Number Number Number Number five times which doesn't make any sense as I am grabbing one row by primary key in this example. Any way I am new at php so any reference for going from xammp to lamp would be appreciated. url is http://ift.tt/1EqF4XR Thank you in advance

  <?php
   $servername = "localhost";
   $username = "root";
   $password = "Mypass";
   $dbname = "test";
    $conn = mysqli_connect($servername, $username, $password, $dbname);
    $sqltest = sprintf("SELECT num, num2 FROM mytest WHERE num = 2");

if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
             }

 $resulttest = mysqli_query($conn, $sqltest);

 foreach($resulttest as $row)
   {
echo("Number".$row['num'].$row['num2']);
  }

      mysqli_close($conn);;
    ?>
