Challenge task 3 of 3 Build a Simple PHP Application

I'm doing a refresher on this course and I am stuck once again.

What am I missing?

Thanks!

palindromic_primes.php
<?php 


function mimic_array_sum($array){
  $sum = 0;
  foreach ($array as $element){
    $sum = $sum + $element;


  }
  return $sum;
};

$sum = mimic_array_sum($palindromic_primes);
echo $sum;


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

?>

Juliette,

You just need to move your $sum variable and the echo statement below the $palindromic_primes array, and you will be good to go!

<?php
// all you need to do is move your $sum variable and its echo statement below the $palindromic_primes array, like so!

function mimic_array_sum($array){
  $sum = 0;
  foreach ($array as $element){
    $sum = $sum + $element;
  }
  return $sum;
};

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

$sum = mimic_array_sum($palindromic_primes);
echo $sum;

Everything else with your code is fine :)

Erik

Ah, that's it. Thanks Erik! Even I got through it the first time (with help), but this time my brain turned into scrambled eggs. Next time will be better:-)

Your pal-prime variable needs to be set before you call a function on it.
