Displaying too many letters?

On the introducing arrays challenge, I end up with too many letters - DGLL instead of DGL. I don't see what it is that is wrong with the code. 

<?php

$letters = array("D","G","L");

echo "My favorite ";
echo count($letters);
echo " letters are these: "; {
    foreach ($letters as $letter){
    echo $letter; }
echo $letter; }
echo ".";

?>

My favorite 3 letters are these: DGLL.

@Elizabeth - You have an extra echo $letter;

Try this code, it should get you sorted out

For future reference when posting PHP it's often easier to troubleshoot if you post a "working" version using a PHP Sandbox

Also if you are working on a specific code challenge/quiz/video it's often helpful to post a link to that and mention at what point you got stuck.
