Description:
------------
It would be very nice to have an array_remove (or some other 
name) function to do what the code below illustrates.

The point of the function is to allow use to retrieve the 
value of a particular key in an array, and remove it from the 
array at the same time. Think of it as array_shift(), but with 
the ability to define the key that gets shifted.

Reproduce code:
---------------
function array_remove ($key, &$array) {
	if (! isset ($array[$key])) return false;

	$return = $array[$key];
	unset ($array[$key]);
	
	return $return;		
}

$array = array ('food' => 'taco', 'drink' => 'juice');

$value = array_remove ('food', $array);

print_r ($array);
print $value;

Expected result:
----------------
FROM print_r:
----
array (
  'drink' => 'juice
)
----

FROM print:
----
taco
----
