Average of values from an array with php

Question

How from this array I can make an average ?

$array=Array
(
    "Element_1" => 255,
    "Element_2" => 95,
    "Element_3" => 100
);

I should get 150.

Answer 1

You can sum the values in the array and then divide them by the count of elements in the array.

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

echo $avg = $sum / $count; 

Answer 2

Try this

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

Answer 3

Use below code :

• array_sum() : Returns the sum of values in an array
• count() : Count all elements in an array, or something in an object

Code:

<?php
$array=Array
(
    "Element_1" => 255,
    "Element_2" => 95,
    "Element_3" => 100
);
echo $average = array_sum($array) / count($array);

Output:

150
