Function not summing to the right number

Your foreach loop is overwriting the return $sum value each time it runs. The return should be the last thing your function does.

The problem is your return statement. You have it in the foreach loop so the loop only adds the first number before it is terminated by the return statement.

Hello Anthony

In your example you where just a little bit too fast with your return value; If you want to have the total sum of your array you need to let the server finishing adding all number before you call a return. For me it helps sometimes to see every single step what the loop is doing, in the code below I let server echo out sum every time after adding another element of the array. After the loop I want to return $sum.

 <?php

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

function mimic_array_sum($palindromic_primes) { 
    $sum = 0; 

    foreach($palindromic_primes as $palindromic_prime){ 
        $sum = $sum + $palindromic_prime; 
        echo $sum . "<br>";
    }
    return $sum;
}

echo "Here is the final value of sum " . mimic_array_sum($palindromic_primes);

?>

I hope I could help you!

the challenge specifies : 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 saw that you give the argument name of $palindromic_primes instead. Try to change them to $array and see if it works :)
