Introducing Arrays

Hi all, I'm stuck on the following code challenge:

The fourth echo statement, the one inside the foreach loop, should display my favorite letters from the array INSTEAD of AB. Remove the static piece of text from that fourth echo statement, changing it instead to display the value for the array element under consideration inside the foreach loop.

Here's my code:

<?php

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

echo "My favorite ";
echo count($letters);
echo " letters are these: ";

foreach($letters as $letter){
echo $letter;
}

echo "AB";
echo ".";

?>

I'm not exactly sure what's wrong here. Any help is greatly appreciated!

What's the final output you see in the preview side? It should be DGL. (You are supposed to remove the code that displays "AB".)

Does that help?

Hey Gregg, from your code it looks like you are getting My favorite 3 letters are these: DGLAB..

If you remove echo "AB"; it will only print the letters "DGL".
