note 77729 deleted from function.array-splice by nlopess

Note Submitter: bill at achieveinternet dot com ---- Note that it's a bit of a misnomer to say that array_unshift($input, $x, $y) is equivalent to array_splice($input, 0, 0, array($x, $y)). While the 2 behave identically in other situations, they behave differently if your array consists of only numeric keys. If you have a numeric-keyed array, array_unshift will reorder your array indices while array_splice will not. If you're trying to maintain the integrity of your indices, then, array_splice is what you should use.
