So what is your question?

 

And what on earth are you doing there? Why would you show all files of the internal application directory (minus a few blacklisted extensions) for everybody to see? Do you not understand how risky this is?

 

If you want to serve a collection of files, you put them into a separate directory, not right between your PHP scripts.

i am two months old with php, i already have a directory and inside he directory are folders in the directory, i want to access the documents in the folders of the directory individually

[Jacques1]

My point is that you must not store your documents in the same directory which contains your PHP scripts, .htaccess files and other internal data, because those are none of the user's business. You have to create an extra folder (let's call it “documents”) and display the content of that folder:

<?php

const DOCUMENT_DIRECTORY = __DIR__.'/documents';    // __DIR__ is the path of the current directory



// iterate over documents in the document directory
foreach (glob(DOCUMENT_DIRECTORY.'/*') as $document)
{
    var_dump($document);
}

This is a lot safer, because the document directory by definition only contains public files (and hidden files like .htaccess are automatically skipped). This also means you can get rid of the blacklisting stuff.

 

Besides that, I'm not sure what you're asking. Do you want to be able to click on a subdirectory and get its content? This is slightly more difficult. You have to make the webserver rewrite all URLs pointing to directories (but not files) within the document directory so that the requests are instead sent to your script (together with the original URL). Within the script, you verify the received path and then display the content.

 

Which webserver are you using? Apache?

 

A word of advice: Since you're new to PHP and have chosen a fairly critical project, I strongly recommend you don't put this online yet. Run it on your PC, use it for learning, but don't expose it to the Internet.
