code to set session in Controller:

<?php
$accesstoken = '123456788fsdfsgsdgewfs';
$this->session->set("token", $accesstoken);
?>

Libary File to check set session is correct or not : But on this page not able to get session

<?php
session_start();
class ValidAccessToken{
    private $user_id;
    private $utype;

    function isValid(){
        $isvalid = false;
        if(isset($_POST['token'])){
            $tokenvalue  = $_POST['token'];
        }elseif(isset($_SESSION['token'])){
            $tokenvalue  = $_SESSION['token'];
        }else{
            $tokenvalue  = "";
        }
        echo 'TOKEN :  '.$tokenvalue."<br/>";
        if($tokenvalue){    
            $accessToken = AccessTokens::findFirstByToken($tokenvalue);
            if($accessToken){
                $this->user_id = $accessToken->user_id;
                $this->utype = $accessToken->utype;
                $isvalid = true;
            }
        }
        return $isvalid;
    }

    function getUid(){
        return $this->user_id;
    }

    function getUtype(){
        return $this->utype;
    }
}

Don't use $_SESSION and $_POST, use $di->get("session")->get() and $di->get("request")->getPost()

i am sorry if i am being annoying here, but i HATE if statments like this so much

 if(($dispatcher->getControllerName()=="user" && $dispatcher->getActionName()=="signup") || 
                    ($dispatcher->getControllerName()=="employee" && $dispatcher->getActionName()=="signupemployee") || 
                    ($dispatcher->getControllerName()=="user" && $dispatcher->getActionName()=="signin") ||
                    ($dispatcher->getControllerName()=="user" && $dispatcher->getActionName()=="checkemail") ||
                    ($dispatcher->getControllerName()=="user" && $dispatcher->getActionName()=="checkmobile") ||
                    ($dispatcher->getControllerName()=="misc" && $dispatcher->getActionName()=="saveotp") ||
                    ($dispatcher->getControllerName()=="misc" && $dispatcher->getActionName()=="sendmsg") ||
                    ($dispatcher->getControllerName()=="misc" && $dispatcher->getActionName()=="checkotp")||
                    ($dispatcher->getControllerName()=="service" && $dispatcher->getActionName()=="getservices"))
$allowedActions = ['user', 'signup'.....]

if (in_array($dispatcher->getControllerName(), $allowedActions) {
    ...
}

so much more readable ..

Also better just use acl xD
