Yaf_Session::start — Start the session
Starts the session if it has not been started yet. This calls PHP's native session start mechanism. Calling this method multiple times is safe.
This function has no parameters.
Returns the Yaf_Session instance.
Example #1 Yaf_Session::start() example
<?php
// typically done once per request, e.g. in a bootstrap
$session = Yaf_Session::getInstance();
$session->start();
$session->set("user_id", 42);
echo $session->get("user_id");
?>
