How to calculate average of array in php?

@ryleigh 

You can calculate the average of an array in PHP by summing up all the elements in the array and then dividing the sum by the number of elements in the array. Here's an example:

1
2
3
4
5
6
7

$array = [2, 4, 6, 8, 10];

$sum = array_sum($array);
$count = count($array);
$average = $sum / $count;

echo "The average of the array is: " . $average;

This will output:

1

The average of the array is: 6
