PHP Build a Simple PHP Application Working With Functions Introducing Functions

stage 6 challenge 1

The code below creates an array of numbers, loops through them one at a time, and sums their values. PHP actually has a native function that does this same thing: array_sum(). [The array_sum() function receives an array as its one and only argument, and it sends back the sum as the return value.] Modify the code below: remove the foreach loop and the working sum variable, replacing them with a call to the array_sum() function instead.

sum.php 
<?php

$numbers = array(1,5,8);
 array_sum(14);


echo $sum; ?>

Hi MUZ140045 gumunyu,

The current code you have isn't quite right as you're not doing the following:

  1. Assigning the returned value of array_sum to the variable $sum
  2. Not passing the $numbers array to the array_sum function.

The final code for this task you should have is as follows.

<?php

$numbers = array(1,5,8);
$sum = array_sum($numbers);
echo $sum;

?>

Happy coding!
