Building a simple PHP application

Stuck on this and its really bugging me.

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) {



}


$palindromic_primes = array(11, 757, 16361);

?>

Hi Shaun, we use the foreach method to loop through the array so we can access its values and add them, we also need to create a $sum variable inside the function so we can add the values in the array together, lastly we must return the $sum variable. Putting all this information together, we can do something like this:

<?php 
 function mimic_array_sum($array) {
    $sum = 0; //create the $sum variable
        foreach($array as $number) { //go through each value in the array (labelled $number)
            $sum = $sum + $number; //add the $number value to the $sum variable
        } 
            return $sum //return the value of $sum
}

$palindromic_primes = array(11, 757, 16361);

?>

Hope that helps!!
