Question

Is it possible to create hidden files/folders on windows using php (xampp)?
And if it is, how?

Answer 1

A file in Windows is hidden if it has the hidden attribute set on it. There is no built in function to do this, so you need to use system/exec to execute the attrib application. Like this:

$file = 'test.txt';
system('attrib +H ' . escapeshellarg($file));

This will set the hidden (+H) flag on test.txt.
