15,719 PointsHi Tinashe,
You are very close with your code! Please note that you must use the $element
contained within the array towards the total sum. This $element
is gathered from the foreach
loop and is the value at each index of the array.
Your goal is to add each number in the array together, so your $count
variable should be set equal to the previous total plus the new $element
in the array until it is done instead of only adding 1 to it each time.
I changed $count
to $sum
because it makes more sense in this situation:
<?php
function mimic_array_sum($array) {
$sum = 0;
foreach ($array as $element) {
//set the sum equal to its previous amount plus the new number in the array
//this provides a running total of all numbers in the array
$sum = $sum + $element;
}
return $sum;
}
$palindromic_primes = array(11, 757, 16361);
?>
