You do not need to destroy session variables. You can
session_unregister() them, if you'd like.
$session_start();
$foo = "Hi";
session_register("foo");
Next page...
if (isset($foo))
{
echo "$foo"; // will print "Hi" if done correctly
session_unregister("foo");
}
Sessions are automatically destroyed when the client-side browser
shuts down and the garbage collector runs. If you want to "force"
a session deletion, use session_destroy(). Use it with caution, though,
since it's usually better to let the garbage collector do the work
periodically instead of cleaning up each session individually.
