Sorry, I never do this, and don't know how to show my code. Here's the cut and paste. Nothing I do in workspaces with this course will work. It says the files are not there. I've typed exactly what she's typed, unless I'm nuts. I didn't think I was confused about any part of the lesson.
<?php
$files = scandir('data');
echo '<ul>'; foreach ($files as $file) { if (substr($file, 0, 1) != '.') { echo '<li>'; echo $file; echo '</li>'; } } echo '</ul>';
?>

Treehouse TeacherHi again! Well, the great news is that there is nothing wrong with your code! However, you created your index.php inside the data folder. And because it's relative to the place where the index.php file is, it's looking for a data folder inside the data folder and that doesn't exist.
To fix this, move your PHP file to be on the same level as the data folder. To be honest, it's probably just easiest if you copy/paste the code, collapse the data folder. then right-click in the black area and create new file, name it index.php and then paste in your code. I sometimes have problems dragging files into folders when using workspaces.
Hope this helps!

I am having the same problem as Russell. However, I have created my index.php file outside the data file .. and it still does not work ... https://w.trhou.se/m7g9c2npgw ...
Thanks for your help. Bára

Treehouse TeacherBára Paulátová I'm not sure what to tell you. When I fork your workspace and click the preview button, you receive the exact same results shown at 6:18 of the video. You might try clearing your browser cache in case it's loading in old (blank) data, but on my end, your code works perfectly!

Treehouse TeacherUnfortunately, the link that you have posted is private to you and temporary. The only way for us to see your workspace is if you post a snapshot of it. I included a link to how to make a snapshot in the comment above. On the upper right-hand side of your workspace is a camera icon. When you click that it will create a snapshot which you can then link here.

Treehouse TeacherAs I posted in your previous question about the same topic, we really need to see your workspace. This is most easily shared with us by creating a snapshot. It could be that there's something wrong with the workspace or the file structure, but we can't help you troubleshoot it without seeing the workspace. I look forward to that snapshot!
