How to Find the Index of the Maximum Value in an Array?

Identifying the Index of Maximum Value in an Array

Consider an array with assorted values like:

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

The goal is to determine the index of the highest value in this array, which in this case, is 14 at index 11.

Solution:

To retrieve the index of the maximum value in an array, you can leverage the following approach:

<code class="php">$maxs = array_keys($array, max($array));</code>

Using this solution, you can obtain an array of all indexes associated with the maximum value. However, if you're only interested in a single index, you can directly access it using $maxs[0].

Output:

For the provided array, the output of the solution will be:

$maxs = [11]

Hence, the index of the maximum value is 11, and the value associated with that index is 14.
