Return index of highest value in an array

Question

From an array that looks something like the following, how can I get the index of the highest value in the array. For the array below, the desired result would be '11'.

Array (     [11] => 14     [10] => 9     [12] => 7     [13] => 7     [14] => 4     [15] => 6 ) 

Answer 1

My solution is:

$maxs = array_keys($array, max($array)) 

Note:
this way you can retrieve every key related to a given max value.

If you are interested only in one key among all simply use $maxs[0]
