How to find the Average of the values in your array

If you want to find the AVERAGE of the values in your array, use the sum and count functions together.  For example, let's say your array is $foo and you want the average...

<?php
$foo = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20);
$average_of_foo_round = floor(array_sum($foo) / count($foo));
$average_of_foo = (array_sum($foo) / count($foo));

echo "Average value Round fractions is ".$average_of_foo_round."<br/>";
echo "Average value is ".$average_of_foo."<br/>";
?>



// Output



Average value Round fractions is 10
Average value is 10.5
