http://php.net/unset

Setting to null should also work, I think, but only in some versions...

The value NULL hasn't been around as long as unset.

And there were minor releases where I THINK it went a bit funky about
whether you'd have that key in the array, for some weird situations...

unset has been around and has worked the same for a lonnnnnnng time.
