If you don't need the whole array sorted, use one of the gazillion other answers obviously ;) But mentioning sort() made me think you phrased your question wrong.

Jacob is right - doing an asort will reorder the array lowest to highest maintaining keys...then do a foreach and the $key=>$value from that will be set to the highest pair after the foreach completes..so you have the highest one right there - the key and the value...

If we use sort() or asort() it may lead to time complexity with n nodes

@Stranger ...which is not necessary for this question/page. A loop (instead of sorting) will be "linear" and therefore will boast better performance.
