How to add an array together without using array_sum [duplicate]

Question

I'm tryng to learn PHP and I'm trying to do it by doing things the long way round. So I came across array_sum() and I was wondering if there is a way to calculate an array without using it.

for example

$my_array = array(10, 80, 30);

I've only got as far as this and I'm stumped. I have looked on google but I haven't found anything.

$implode = implode(",", $my_array );

$explode = explode(",", $implode);

foreach($explode as $test)
{


 }

$my_array would be the same as $explode. Can you tell us what are you trying to do? — mighty_dev

Whenever a native function is there, use it. Because it is optimized. Don't invent the wheel, again. — Markus Zeller

I will always go for native functions as they are optimized as well as tested.[so basically i want to say that use array_sum()],

Apart from above, below is foreach() process to sum all values of a single-dimensional array[just for knowledge sake]

<?php


$result = 0; //create a variable with 0 value
foreach($explode as $test)
{
  $result += $test; //add array value to the newly created value

}

echo $result; //print final sum of all array values
