Reference - What does this symbol mean in PHP?
I am studying PHP MVC using this tutorial.There I found the following special notation used for object initialisation
$this->$model =& new $model;
I know & is used for representing ampersand(&) in HTML.What does it mean here?.The class in which the notation is found is given below.Also what about that tutorial?.Is it a good one?.If not can anybody refer me a better one?
<?php
class Controller {
protected $_model;
protected $_controller;
protected $_action;
protected $_template;
function __construct($model, $controller, $action) {
$this->_controller = $controller;
$this->_action = $action;
$this->_model = $model;
$this->$model =& new $model;
$this->_template =& new Template($controller,$action);
}
function set($name,$value) {
$this->_template->set($name,$value);
}
function __destruct() {
$this->_template->render();
}
}
