A little confused about session_destroy()

Well I'm trying to code this small logout.php, and I use session_destroy(). Well as far as I have read in the documentation, session_destroy() is something like the opposite of session_start(), doesn't accept parameters as I know. Calling session_destroy() alone causes an error from PHP, telling me that I am trying to destroy an unitialized session. Bear in mind, that I a session running before calling session_destoy(). Some people have told me that I have to first register the session variables that I used earlier before calling the destroy() function. Well I did try that, didn't seem to work . Calling Session_Unregister, or Session_Unset doesnt work too Could someone help me out here as I'm really not sure what is the problem here ? -- Perry Loh Lead Developer, KlikInTouch.com perryloh@klikintouch.com - Just about Anywhere you go -
