$session->read('Config.language');

Answer 1

Update : For CakePHP 3.6+, see @shubham715 answer

The following applies to CakePHP before 3.6 :

You need to set $session :

$session = $this->request->session();
$session->write('Config.language', 'eng'); 
$session->read('Config.language');

And then you'll be able to read and write in your session

Or you can direclty read and write :

$this->request->session()->write('Config.language', 'eng');
$this->request->session()->read('Config.language');
