/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

if (
$stmt = mysqli_prepare($link, "SELECT Name FROM Country WHERE Name=? OR Code=?")) {

    
$marker = mysqli_stmt_param_count($stmt);
    
printf("Statement has %d markers.\n", $marker);
