Keeping right and wrong answers in PHP


Each request is stateless so you need a way to store the variables between requests. In your case, the simplest way is with session variables.

<?php
session_start();
if (!isset($_SESSION['win'])) {
    $_SESSION['win'] = 0;
}

// ...

if ($_POST["firstdata"] == $random) {
   $_SESSION['win'] += 1;

   // ...

From there you should be able to figure out the rest.
