i have 2 controllers (AuthController.php, AdminController.php) and one master page for a login/registration system. the sess_destroy() is in AuthController and i used construct method to check if the user is logged in or not, if logged in it redirect to (AdminController/home). i put an anchor in the master page to logout(or destroy session). the problem is when i click on logout the session is not destroying. the page is redirects to (Authcontroller/login) and again redirecting to (AdminController/home).

}
}

{
$this->login();
