Introducing Arrays Task 5 of 7 (SOLVED)

I am having a hard time understanding the directions for task 5 on Introducing Arrays. After watching the tutorial video twice I cannot really grasp what is being asked? Can someone help me out here? I believe this is the supplied code...

<?php

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

    echo "My favorite ";
    echo "3";
    echo " letters are these: ";
    echo "AB";
    echo ".";

?>

Hint: Implement the foreach syntax.

foreach ($letters as $value) {
    statement;
}

If you're still stuck I'll try to respond tomorrow!

I tried implementing the foreach syntax in where it said to do so, and I was getting an error that said I had too many :'s in the code. Odd because I didn't put a single colon in the code. I GREATLY appreciate this site and what it can offer but it seems like every code challenge gets hung up because of the instructions and I spend 20 minutes trying to see where I went wrong, only to spend another hour in the forums. I will go back in and try again and hopefully figure it out. Thanks for the help Aimee.

Hey @Tim, Sorry you are having trouble! In this code challenge, we're trying to create an array of my favorite letters and then display that information from the array to the screen.

  • So far your array looks good.
  • The code to display the number should use count($letters) so that it always shows the number of elements in the array.
  • Instead of showing "AB" the code should use a foreach loop so that it pulls the letters feom the array ("DGL") instead.

Does that help?

Found my error. I was placing my foreach syntax in the wrong area. I read it as "Between line 3 and 4" but it was actually "Between echo 3 and 4". I finished the rest of the challenge. Thanks for the help everyone!
