Insert an array in PHP not at end/start

I know it's more PHP related that Geeklog related, but can you please tell me if I can insert one array inside another, but not at the other's end/start and without knowing the numeric position of where I want to insert it?

It's based on machinari's tip to use an array for $message for an endless possibilities' contact form. For some long reason, I need a certain spelling for my array keys in the contact form and another in my e-mail message...

For example,
print_r($array1);
Array
(
["test_one"] => whatever
["test_tow"] => whatever
["test_three"] => whatever
)

Oops (again, not really), I wrote "tow"...now I want to rename it right, but, as far as I can tell, PHP won't let rename array keys.

So I just want to insert "test_two" before/after the "test_tow", only it's dynamic (because I have many of these fields and I have an automatic loop that goes through the array).
Anyway, if I manage to do that, then I'd use:

unset($array1["test_tow"];

and therefore "test_two" would lie safely in the position which once belonged to "test_tow" (position 1 - but only in this specific example).
In other words, I'd end up with:
print_r($array1);
Array
(
["test_one"] => whatever
["test_two"] => whatever
["test_three"] => whatever
)

See how not only "test_tow" turned into "test_two", but also took its position?

Can I do that (or better yet, simply rename array keys)?

Thanks!

Ok, Here it is there.

Meanwhile, I've come up with a solution - using array_flip - that way I can get the old key's offset and, once I have the offset, use some array functions to split and merge at the correct spot.
To those who need them, find more details at the linked post.
