You're wrong, he isn't using an associative array, since the keys used are
only integers.
array(10,10,40,30,30,10);
and
array(0=>10,1=>10,2=>40,3=>30,4=>30,5=>10);
create the same array.
The problem is that array_unique preserves keys (read the manual!!!)
If you don't want this, use array_values() to turn the array into a more
traditional array:
$a = array_values(array_unique($a));
