Introducing User Defined Functions - Challenge Task 1 of 3

Hey there,

I'm really not getting the hang of this specific exercise:

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.)

I understand that I should add a mimic_array_sum( ) function, but other than that, I'm not really sure what else I should do. Here's my code:

<?php
mimic_array_sum($array) {
};

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

Any help is appreciated. Thanks!

Hello,

First off, as far as the semicolon at the end of the function goes, you can have it there if you want to as it is valid PHP code. Your issue stems from the declaration of the function. Remember, you are declaring/defining a function therefor you need the function keyword before the definition. The function keyword tells PHP that you are defining a function. Add the keyword in front of the function declaration and the challenge will pass.

Cheers!

Hey Dan..

Function looks fine apart from the semi-colon after the closing brace, remove that and you should be fine! :)

HTH.
