Retrieving a session ID from a cookie

[Anon]

Hi everyone,

I have a question about sessions. I have the following code and I do not know why the session ID is not being "echoed" by the line "echo $cookieinfo". I seems like 2 possiblities:

1) The cookie wasn't set properly with the session ID

2) Some code here does not retrieve the session ID properly - the "$cookieinfo = $HTTP_COOKIE_VARS["sessionIDSet"]" line ??

Thank you for any input!

check for a cookie on the client's side called sessionIDSet

$cookieinfo = $HTTP_COOKIE_VARS["sessionIDSet"];

if there is a cookie, get it and retrieve the session id

if($cookieinfo == session_id()){

resume the previous session

session_start(session_id());
$sesid = session_id();
echo $cookieinfo;
else{
session_start();

set the Cookie with the session ID setcookie("sessionIDSet", session_id(), time() + 60 * 60);

}

Make sure you have session.use_cookies switched on in the php.ini

Also, the sessionid cookie already contains the sessionid, so if there is any sessionid cookie, it will be used for the sessionid, so checking if the current session has the same id as the id you got from the cookie is redundant.
No cookie, no session. Yes cookie, than that has to be the correct sessionid.

You don't have to 'resume the session' PHP will do that for you automatically.
