What does your connection look like?

<?php $servername = "localhost"; $username = "id20329128_xxxxxx"; $password = "xxxxxxxxxxx"; $dbname = "id20329128_Report"; $conn = mysqli_connect($servername,$username,$password,$dbname); if($conn) { echo "Connection Ok"; } else { die("Connection failed because ".mysqli_connection_error()); } ?>
