Here is the correct code.

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

echo "My favorite "; echo "3"; echo " letters are these: ";

foreach($letters as $letter){ echo $letter . "\n"; } echo "AB"; echo ".";

?>

You are using -- echo $letters -- instead of -- echo $letter -- . $letters is an array whereas $letter is a variable. Each time foreach statement loops through $letters it will assign the value of the current array element to $letter and the array pointer is moved by one, until it reaches the last array element.
