A function similar to array_shift, only by key (remove array element) - NON-BRED?

Question

PHP

Hello.
I must say right away that the issue is easily solved as follows:

$arr = array('one' => 1, 'two' => 2);
$two = $arr['two'];
unset($arr['two'];

BUT how to do it right?
something like array_shift but by index?
What for? I just thought how to do it more correctly, + you need to get everything unnecessary from the array, and pass it on.

Answer 1

you can get everything you don't need with the array_filter filter
