How to get guest user sessionid in Yii2?

Question

I have used YII's session_id's to track user activity across a website with the following code snippet:

Yii::app()->getSession()->getSessionId()

How do I get same sessionid in Yii2? I tried quite possible way, but its all vain.

Please share the exact code snippet for Yii2.

Solution 1

You can try with

Yii::$app->session->getId();

this guide could be useful to you http://www.yiiframework.com/doc-2.0/guide-runtime-sessions-cookies.html

try checking if a session is already active before and ifnot use session open() .

session = Yii::$app->session;

// check if a session is already open
if ($session->isActive) ...

// open a session
$session->open();

// close a session
$session->close();

// destroys all data registered to a session.
$session->destroy();

Solution 2

$session = Yii::$app->session;

// if session is not open, open session
if ( !$session->isActive) { $session->open(); }

// get session id
Yii::$app->session->getId();

I got 26 character string in session id. "itddoa1lr247phpds34aemr0v0"
