Introducing User-Defined Functions task 2 of 3 : Broken?

On Introducing User-Defined Functions task 2 of 3 I am trying to pass this code challenge.

"Write the code inside this mimic_array_sum() function. That code should add up all individual numbers in the array and return the sum. You’ll need to use a foreach command to loop through the argument array, a working variable to keep the running total, and a return command to send the sum back to the main code."

Below is my code, I even tried another users 'verified' code in a previous post and while it passes for some it doesn't for others.

The error I get is

"Bummer! The sum of the three numbers in the array should be 17129. (If you need assistance with the code inside the function, check out the starting code for the previous Introducing Functions challenge.)"

Is this a bug in the code challenge?

<?php
  function mimic_array_sum( $array ) {

    $count = 0;

    foreach ( $array as $arrays ) {
        $count = $count + $arrays;
      return $count;
    }

  };

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