note 112916 added to function.array-diff

Please note that array_diff cannot compare with an undefined array. For example: <?php $array1 = array ("ABC", "DEF"); $Result = $array_diff( $array1, $array2); var_dump($Result); ?> will output NULL NULL. If your script causes an undefined array (like mine did) it can be hard to find the mistake.
