PHP get array key for lowest array value

Using PHP, I am creating an array that contains multiple keys:

$loadAverage[$server] = $output["now"];

I am then checking the item with the lowest value

echo min($loadAverage);

but i need to get the key of the array not the value (so the $server part i need)

the above is returning the value and not the key of the PHP array

$lowest_key = array_keys($loadAverage, min($loadAverage));
echo $lowest_key[0];

By supplying a search element you only get the key of that value.
