thanks for getting back to me!
unfortunately I'm not getting it to work.
I created a new file called tree.php with the following snippet at the very top:
$path = $_GET['path'];
followed by the lines 25-378 of the attached file
in the attached file I have removed lines 25-378 and inserted above the heredoc snippet:
while my IDE does not show any syntax errors and there are also no errors displayed on user side the tree is not being displayed anymore
would you have any advice what I'm overlooking?
