Couldn't you just do
arsort($chance);
$lastItem = chance[( count( $chance ) - 1 )];
I tried that earlier, but the problem is:
count( $chance ) - 1 ); returns an integer, so I would be asking for something like $chance[1] or $chance[0], neither of which exist in the array. Keep in mind $chance only has keys with string names:
http://uk3.php.net/current
$chance = array("lowercase" => 27, "uppercase" => 62, "integer" => 46);
arsort($chance);
max() returns the maximum value of an array.
array_search() finds the key for a value
So all that's needed to find the key of the maximum value is:
$result = array_search(max($chance), $chance);
I'd pretty much guarantee it'll be about an order of magnitude faster
than any solution that relies on sorting the array.
