<?php

function array_key_first(array $arr){
foreach($arr as $key=>$unused){
return $key;
}
return NULL;
}
}

- solution of "mirko dot pagliai at gmail" is slow, solution from "mail at vitalyart
dot ru " edits the internal array pointer, the solution from "devonblzx" is slow, and
the solution from "manzoorwanijk" is.. ok i guess, but this is better.
