Welcome to Treehouse!

It looks like your Array code is correct and you are choosing the correct array item to display. The code challenge doesn't like things outputted it is not looking for, and as such if you remove your var_dump line your code works just fine. One of the things to remember as you work through the challenges here at Treehouse is to generally not add any extra code to them that is not requested. The challenge engine checker will generally reject your code.

Happy coding,

Ken

Your code is valid. Maybe you're getting an error because of the var_dump()?

<?php

//Place your code below this comment
$integer_one = 1;
$integer_two = 2;

$golden = 1.618;

$bool = true;

$colors = array('red', 'blue', 'green');

echo $colors[1];

?>

Works just fine for me.

Hey Mind B,

Well, you do have a "var_dump()" execution going on that is unnecessary, and that is causing the Challenge to error out. You should get rid of the unnecessary var_dump execution and that will allow you to carry on in the challenge! :)
