I want to calculate the average from a key contained in the array.
Array
(
[123456] => Array
(
[Log] => 2793
[Approve] => 1724
[Accept] => 13863
)
[123457] => Array
(
[Log] => 2606
[Classify] => 730
[FirstLineSupport] => 83339
[Escalate] => 14689501
[Fulfill] => 14772840
)
[123458] => Array
(
[Log] => 2700
[Approve] => 16152972
[Fulfill] => 73006092
[Accept] => 729914
[Review] => 27033
)
)
In this case I need to calculate the average of key "Fulfill".
So I need to calculate:
(14772840 + 73006092) / 2 = 43889466
I know I can sum the values using:
$sum = array_sum(array_column($arr, 'Fulfill'));
But how can I divide by the number of occurrences of the key?

Put the result of
array_column()
in a variable. Then you can get the length of that array.Just one line more:
