I think the order of your statements may be not be correct for what the challenge wants as expected output. Also at some point you have to remove or comment out the echo 'AB'; line.

Here is my result for the challenge. I don't like to give answers to copy/paste, but I can see how this may a little confusing. Also, my code may not be the only way to pass, although I think order of statements is important.

<?php
$letters[] = 'D';
$letters[] = 'G';
$letters[] = 'L';
$letters[] = 'R';
echo "My favorite ";
echo count($letters);
echo " letters are these: ";
foreach ($letters as $letter) {
  echo $letter;
}
//echo "AB";
echo ".";

?>
