Question

Specifically, I would like to create an Array class and would like to overload the [] operator.

Answer 1

If you are using PHP5 (and you should be), take a look at the SPL ArrayObject classes. The documentation isn’t too good, but I think if you extend ArrayObject, you’d have your "fake" array.

EDIT: Here’s my quick example; I’m afraid I don’t have a valuable use case though:

class a extends ArrayObject {     public function offsetSet($i, $v) {         echo 'appending ' . $v;         parent::offsetSet($i, $v);     } }  $a = new a; $a[] = 1;
