How to pass multiple objects to a template? - php

Question

I am trying to understand the MVC method with the use of OOP. However it seems like I've hit the wall here.
I am trying to pass multiple objects to the view. But all I can do so far is pass just one object. The ideal result would be passing multiple objects, while keeping the names that are assigned to them in the controller.
The render, start and end functions in the View class go something like this:
public function render($viewName, $data){
$viewAry = explode('/', $viewName);
$viewString = implode(DS, $viewAry);
if(file_exists(ROOT . DS . 'app' . DS . 'views' . DS . $viewString . '.php')){
include(ROOT . DS . 'app' . DS . 'views' . DS . $viewString . '.php');
include(ROOT . DS . 'app' . DS . 'views' . DS . 'layouts' . DS . $this->_layout . '.php');
}else{
die('The view \"' . $viewName . '\" does not exist.');
}
}
public function content($type){
if($type == 'head'){
return $this->_head;
}elseif ($type == 'body'){
return $this->_body;
}
return false;
}
public function start($type){
$this->_outputBuffer = $type;
ob_start();
}
public function end(){
if($this->_outputBuffer == 'head'){
$this->_head = ob_get_clean();
}elseif($this->_outputBuffer == 'body'){
$this->_body = ob_get_clean();
}else{
die('You must first run the start method.');
}
}
And this is how would the controller look like:
public function indexAction(){
$items = $this->PortalModel->getItems();
$collections = $this->PortalModel->getCollections();
$this->view->render('home/index', $items);
}
So this is how I get the one $data object to the view and loop trough it.
But how could I store multiple results from the database to the view?

You should pass an array of variables into view instead of one variable.
public function indexAction(){
$variables = [
'items' => $this->PortalModel->getItems(),
'collections' => $this->PortalModel->getCollections()
];
$this->view->render('home/index', $variables);
}
