Lost with no hints

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.)

I have watched the video several times and still can't get this one right, what is the code supposed to look like? I have no idea what to try next.

Hey @Jason,

Where the code has this ...

echo "AB";

... you need to change it to this ...

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

Does that help?

I'm working on this challenge ATM. I'm pretty sure I have everything right, but it still says I'm wrong. This is my code...

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

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

?>

Possibly BUG????

Hi Jason, can you be more specific about the project, stage, and code challenge you're working on? Adding tags to the post might help get the appropriate people to find your questions as well.

Take a look at the output in the right. At this step, I believe it should say this:

My favorite 3 letters are these: AB.

If you look at the output, I suspect your output has more than that. Modify the code so that it displays exactly what you see above.

Does that help?
