How can you output the value with the largest key in a given PHP array?

To output the value with the largest key in a given PHP array, you can use the max() function to find the largest key in the array and then access the corresponding value using that key. This can be achieved by first getting the key with the maximum value using the max() function, and then accessing the value in the array using that key. 

$array = array(10 => 'a', 20 => 'b', 30 => 'c');
$maxKey = max(array_keys($array));
$maxValue = $array[$maxKey];

echo $maxValue;
