Question

$em = $_GET['token'];
$emid = $_GET['tokenid'];
$_SESSION['foo'] = $em;
$_SESSION['fooid'] = $emid;

but it is not creating sessions ... how can i solve that

Answer 1

Did you remember session_start() before assigning the values?

See the manual if you are in doubt.

If you really mean that you want to create a session from the tokens you should have look at session_id().
