Stuck in the PHP Development Code Challenge: Introducing Arrays

Hi, this is the 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.

However, I couldn't understand what does it ask for in the second sentence. It is keep saying: Bummer! You seem to have too many letters. You should only be displaying one letter inside your foreach loop.

Can someone help please?

Thanks! :)

letters.php 
<?php

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

?>
<pre><?php
echo "My favorite ";
echo count($letters);
echo " letters are these:\n";
foreach($letters as $letter) {
  echo $letter . "/n";
}

echo "A B";
echo ".";

?>

The output for your code is basically correct, I imagine the problem stems from the use of the <pre> tag. Occasionally formatting issues will cause "Bummers" in treehouse. I cleaned up your code above and got it to pass successfully.

A great resource to test and debug code for these challenges is: http://sandbox.onlinephpfunctions.com/ This sandbox will allow you to see if your code functions correctly, and if not you can find the line number and error type. 

<?php

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

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

?>

Hope this helps!

Try removing echo "A B";. If that doesn't work you might need to remove the new-line characters.

I have ended up like this:

<?php

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

?>
<pre><?php
echo "My favorite ";
echo count($letters);
echo " letters are these:";
foreach($letters as $letter) {
  echo $letter;
}

echo ".";

?>

But it keeps saying: "Bummer! You seem to have too many letters. You should only be displaying one letter inside your foreach loop."

Anymore ideas?
