Does PHP have built-in array function to remove specific key and return removed?

Question

I want something that works like array_pop() or array_shift(), so it returns the removed element, but I'd like to specify by key which element to remove.

Example:

$arr = ['a' => 1, 'b' => 2, 'c' => 3]; 
$removed = array_remove($arr, 'b');

print_r($arr); // Outputs: Array(['a'] => 1, ['c'] => 3 )
print_r($removed); // Outputs: 2

Now I'am using

$arr = ['a' => 1, 'b' => 2, 'c' => 3]; 
$removed = $arr['b'];
unset($arr['b']);

If you go to the manual, you can go through the existing array functions and check if any of them does what you want. There aren't that many... — M. Eriksson

What's wrong with your current version? As it's only 2 lines long, it's hardly bloating your code. — Nigel Ren

No but it would be trivial to make array_remove. 3v4l.org/lhFMI — Lawrence Cherone

I believe your solution is readable, the most performant and that there is not a reserved function for what you want. — Pedro Amaral Couto

That won't work with hash maps and the removed value is not returned. The second argument must be an integer and the return type is an array.
