Yummie cookies

[Mark-K]

I'm trying to work out how to get a cookie I made to be usable.

I've never learnt any other language before PHP do I've never really learnt sessions and cookies so I've been having a nightmare understanding them
I've got everything right it's putting the data in the database and making a server session etc...

Anyway, I need to be able to get a session id i put in a user cookie, I set the cookie up like

setcookie("sessid", $sid, time()+43200, "/", "", 0); 

And don't know how to get the data back.

I've tryed using $HTTP_COOKIE_VARS['sessid'] and it don't seem to work. I guess I gotta use session_get_cookie_params() but I don't know how to use it.

Please help before I die from stress

If the cookie is set correctly you don't actually need to do anything to 'get the cookie back' - if you set the cookie

 setcookie("sessid", $sid, time()+43200, "/", "", 0); 

To use it you can just use $sessid.

Cheers dunno spose I'm just dumb lol.
I tryed echo $sessid; and it showed, there must be an error somewhere else in my code to why its not using it
