The error I'm getting is that my function is not "summing" up the array but I feel that my function is doing that. Here's the code below.
<?php function mimic_array_sum($array) { $count = 0; foreach ($array as $arrays) { $count = $count + $arrays; return $count; } };
$palindromic_primes = array(11, 757, 16361); echo $count = mimic_array_sum($palindromic_primes); ?>

It looks like you put the return $count; inside the foreach loop. Move it outside of the loop and that should fix your problem. Your current code is returning the value and exiting the function before it can move to the second item in the array.

function mimic_array_sum( $array ) {
$sum = 0;
foreach ( $array as $element ) {
$sum = $sum + $element;
}
return $sum;
}
That way you have completely summed all of the values in the array prior to returning the final sum. You only want to return the sum once when all of the array elements have been looped through.

29,247 PointsHehe, it happens. I usually write up my answer, highlight it, copy it, then refresh the page to see if someone posted the same answer that I was writing up. If all is clear, I paste it back in the answer box then click the post answer button. I'm a bit obsessively compulsive about it.
