In nearly every tutorial (including the php manual) you add items to the end of an Array by writing this:
$array[] = $item;
Which is a tad odd, but I have just gotten used to it.
But today I stumbled across a peice of code where they fiddle a bit with the spaces to make that look like an operator!
$array []= $item;
Which looks great and makes a tad more sense.
