Hi guys wanted to also add on how to copy using a dynamic copying and pasting.

let say we don't know the actual folder the user will create but we know in that folder we need files to be copied to, to activate some function like delete, update, views etc.

you can use something like this... I used this code in one of the complex project which I am currently busy on. i just build it myself because all answers i got on the internet was giving me an error.

    $dirPath1 = "users/$uniqueID"; #creating main folder and where $uniqueID will be called by a database when a user login.
    $result = mkdir($dirPath1, 0755);
            $dirPath2 = "users/$uniqueID/profile"; #sub folder
            $result = mkdir($dirPath2, 0755);
                $dirPath3 = "users/$uniqueID/images"; #sub folder 
                $result = mkdir($dirPath3, 0755);
                    $dirPath4 = "users/$uniqueID/uploads";#sub folder
                    $result = mkdir($dirPath4, 0755);
                    @copy('blank/dashboard.php', 'users/'.$uniqueID.'/dashboard.php');#from blank folder to dynamic user created folder
                    @copy('blank/views.php', 'users/'.$uniqueID.'/views.php'); #from blank folder to dynamic user created folder
                    @copy('blank/upload.php', 'users/'.$uniqueID.'/upload.php'); #from blank folder to dynamic user created folder
                    @copy('blank/delete.php', 'users/'.$uniqueID.'/delete.php'); #from blank folder to dynamic user created folder

I think facebook or twitter uses something like this to build every new user dashboard dynamic....
