opendir function

[ippo]

what does opendir('.') in php do?
What is '.' inside the bracket does?
A '.' cannot be a string path!!

'.' is a relative path. It means this directory, which in PHP will be the same directory as the executing script. '..' would mean up one directory.

.. in dos was always at the top of any directory listing along with .

They've both been used since the age of the dinosaurs in computer operating systems and are both perfectly valid in php code too

Or pretty much any other OS command line, including unix, linux, BSD, etc.
