Copy files from one dir to another dir ?

How can I copy some files from one dir to another dir by PHP?

Suppose, my dir structure -

From dir: /files/video/(some files here)

To dir: /files/new/

 

If you just read this: http://us3.php.net/manual/en/function.copy.php

Read the first (or second) comment and you'll see a function to do so (recursive copy entire directory).

 

copy('files/video/filename.ext','files/new/filename.ext');
