----

This is a super-hard array conversion function.
It only returns TRUE if the two arrays are completely identical, that means that they have the same keys, and the values of all keys are exactly the same (compared with ===).

<?php
function array_same($a1, $a2) {
  if (!is_array($a1) || !is_array($a2))
    return false;
  
  $keys = array_merge(array_keys($a1), array_keys($a2));
  
  foreach ($keys as $k) {
    if (!isset($a2[$k]) || !isset($a1[$k]))
      return false;
      
    if (is_array($a1[$k]) || is_array($a2[$k])) {
      if (!array_same($a1[$k], $a2[$k]))
        return false;
    }
    else {
      if (! ($a1[$k] === $a2[$k]))
        return false;
    } 
  }
  
  return true;
}
?>
