PHP Get Highest Value from Array

Question

I'm trying to get hold of the largest value in an array, while still preserving the item labels. I know I can do this by running sort(), but if I do so I simply lose the labels - which makes it pointless for what I need. Here's the array:

array("a"=>1,"b"=>2,"c"=>4,"d"=>5); 

Any ideas?

Answer 1

Don't sort the array to get the largest value.

Get the max value:

$value = max($array); 

Get the corresponding key:

$key = array_search($value, $array);
