Write the code inside this mimic_array_sum() function. That code should add up all individual numbers in the array and return the sum. You’ll need to use a foreach command to loop through the argument array, a working variable to keep the running total, and a return command to send the sum back to the main code.
<?php
function mimic_array_sum($array) {
foreach($array as $element) {
$count = $palindromic_primes[0] + $palindromic_primes[1] + $palindromic_primes[2];
}
}
return mimic_array_sum($array);
$palindromic_primes = array(11, 757, 16361);
?>

$count = $palindromic_primes[0] + $palindromic_primes[1] + $palindromic_primes[2];
There's no way to know that each time a user inputs numbers, that they are always going to input 3...they might enter 2 or even a million, i would approach this in the following way:
<?php
function mimic_array_sum($array) {
$sum = 0;
foreach($array as $number) {
$sum += $number;
}
return $sum; //return the value of $sum
}
$palindromic_primes = array(11, 757, 16361);
?>
You declare a $sum variable outside the foreach loop and then add to it through each iteration of the loop so it goes like:
loop 1 - 0 + 11 = 11
loop 2 - 11 + 757 = 768
loop 3 - 768 + 16361 = 17129
This way the user can enter in as many numbers as they want and the code will still execute :)
