Just to illustrate the behaviour of the internal pointer when you add items. Adding to an array does not affect the internal pointer. <?php $a = array(); var_dump(key($a)); // null $a[] = "jump"; var_dump(key($a)); // 0 $a[] = "lazy"; var_dump(key($a)); // 0 end($a); var_dump(key($a)); // 1 $a[] = "fox"; var_dump(key($a)); // 1 ?> --was-- Just to illustrate the behaviour of the internal pointer when you add items.
