Foreach Loop

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.)

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

?>

Hi Andrew,

Please link to the challenge you're on and also you want to use the backtick when posting your code.

See this thread: https://teamtreehouse.com/forum/posting-code-to-the-forum

I don't see foreach in your code. Which task are you on?

Ok, now I see it.

See if you can get your code posted correctly so we can see the html too.

did you change the echo commands of the challenge at all? you dont have a foreach loop in your code either. the instructions say the output should be "my favorite letters are ABABAB.". whereas right now you have "my favorite 3 letters are these: AB". Dont change the output of the challenge if it doesnt say to. something like this may work but cant be sure without a link to the actual challenge:

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

?>

This is the correct - This worked, thanks for the help

<?php

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

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

?>
