One problem, karq, and that is your number (not the guess) doesn't persist. This means that if the number is 1 the first time and I say 3, the returned message is that the number is smaller. So, next time I pick 2 ... only to have it tell me the number is bigger.

Try using a cookie to make the random number persist.

PHP Code:


			
<?php

// This MUST be at the top before ANY output happens!
if(!isset($_COOKIE['arva'])) {
  // The zero makes it expire when the browser session terminates.
  setcookie('arva', rand(1,20), 0);
}
$arva = intval($_COOKIE['arva']);
?>

Now, put that at the top and remove the parts within your section that assign values to arva. Now it'll persist between guesses and you can get it right.
