PHP Build a Simple PHP Application Working With Functions Introducing User-Defined Functions

I do not understand..help

In the previous code challenge “Introducing Functions,” we called PHP’s array_sum function to calculate the sum of the values in an array. In this code challenge, we’ll create a function that mimics that one. First, create a function named mimic_array_sum. It should receive one argument, an array of numbers to be summed. Name that argument $array. (Be sure to specify a pair of curly brackets where the code this function executes will go.)

<?php 





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

?>

Give this a shot:

 <?php 
        function mimic_array_sum($array) {
                      $sum = 0;
                 foreach($array as $element) {
                             $sum = $sum + $element;
                       } 
                       return $sum;
                }
           $palindromic_primes = array(11, 757, 16361);
           ?>
