Stuck on Code Challenge in Build a Simple PHP Application

Question

So it's time for me to call on some help. I am stuck on a code challenge. So I get the first part correct which brings my code to:

<?php
$letters = array("D","G","L");
echo "My favorite ";
echo count ($letters);
echo " letters are these: ";
echo "AB";
echo ".";
?>

The next step gets me confused, it says: Right now, the text shows the wrong letters; we want it to display my real favorite letters from the array. In the next few tasks, we’ll change that. This task has two steps. (1) Add the start of a foreach loop with an opening curly brace between the third and fourth echo commands. The foreach loop should load each element from the letters array, one at a time, into a working variable named letter. (2) Add the closing curly brace for the foreach loop between the fourth and fifth echo commands. (Leave the letters AB in the fourth echo command for now. At the end of this step, the page should say my favorite letters are ABABAB.)

So my code is:

<?php
$letters = array("D","G","L");
echo "My favorite ";
echo count ($letters);
foreach($letters as $letter) {
  echo $letter . "\n";
}
echo " letters are these: ";
echo "AB";
echo ".";
?>

I find what is being asked very confusing and then it starts to say that my code is now not recognised for the task before. Any help much appreciated as I have tried and tried but I'm proper stuck.

So it looks like you got the lines wrong, and you got ahead of yourself. Basically what it's asking is that the only line inside the foreach loop is the one that says echo "AB";. So your loop needs to start below echo " letters are these: "; and should contain that line. You're not echoing out $letter quite yet.

Developers are hot these days... :)

Melanie as Stephen Crockett mentioned you are getting ahead. The goal of the quizz is to go step-by-step so that you can understand what the code is doing regardless of what the goal is. In this case I assume they want to be sure that you understand that the foreach loop is looping the code inside 3 times because it's the array length.

<?php

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

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

?>

I still don't get this one... I'm doing everything correct and can't figure out how what they are looking for in step 6?????

<?php

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

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

?>

What is wrong with this?
