php - Getting contents with extract($variables), but the variables are undefined -


i haven't gotten hang of extract() function, , transferring variables. have method in user controller variables defined, , sent in array view function in parent controller, array extracted. view required. variables turn out undefined. array contents can printed though.

here user controller simplified profile function:

class user extends controller{      public function profile(){           $profiledetails = $this->profiledetails();                     $profilestatus = $this->profilestatus();                       $this->view('profile', [$profiledetails, $profilestatus]); }}

the variables sent view function in parent controller:

class controller {     public function view($view, $variables =[]){                          extract($variables);      require_once './app/views/' . $view . '.php'; }}

and in view, 'profile.php', undefined variable error shown. thought "extract()" function make $profiledetails , $profilestatus available variables in view. doing wrong? maybe i'm using wrong type of array, or should use "variabe variables" or something.. (in case, how?).

extract works associative array. 

    $this->view('profile',        [         'profiledetails' => $profiledetails,          'profilestatus' => $profilestatus       ]);
