[PHPycho]

hello forums !!
I would like to know how to use session_regenerate_id() effectively..
i tried it as:

session_start();
if(!empty($_SESSION)){
	session_regenerate_id(true);
}

i dont whether it is correct or else .
Hope to have same comments on it.
Thanks in advance

The syntax looks fine, but whether it is the proper solution for whatever you are trying to do cannot be answered without more info.
