php - Custom MVC, how to implement a render function for the controller so the View can access variables set by the Controller -

i'm adding new features existing code base. anyway, current feature i'm doing should in mvc in opinion. existing code base isn't mvc feature i'm implementing, want mvc. , don't want roll existing mvc existing codes.

so, problem is... don't know implement render function controller class. usually, in mvc have controller stuff, set variable using render function, , view can magically access given variable set controller.

i have no idea how other global, feel wrong, keep on telling myself there has better way. edit: it's global isn't it? >_> how other frameworks it?

here's silly example:

controller:

class usercontroller extend basecontroller  { public function actionindex()  {   $user = new user; // create instance user model    $user->getlistofuser();    $this->render('listofuser', 'model'=>$model); } } 

view:

<?php //i can use $listofuser now... //some loop echo $listofuser[$i]; ?> 

thank in advance!

a simple example:

class view {     function render($file, $variables = array()) {         extract($variables);          ob_start();         include $file;         $renderedview = ob_get_clean();          return $renderedview;     } }  $view = new view(); echo $view->render('viewfile.php', array('foo' => 'bar')); 

inside viewfile.php you'll able use variable $foo. code in view file have access $this (the view instance) , variables in scope inside render function. extract extracts array's contents local variables.
