POget value of private var in a class through typehinted object to assign it in php 5.3
text
Body
copied!<p>I have been reading Rafactoring by Martin Fowler and in the beginning of the book he uses an example application (written in Java), which I am trying to convert over to PHP for training purposes. (I have trimmed the code down to make this question, but it works if the variables are public.)</p> <p>The trouble is to create a statement I need access to a value (see switch) using method getCode() of Movie class since $code is private. (Of course if all of the variables were public the code below would work, but I want to keep them private.)</p> <p>Can someone please shed some light on how I would access the private variable calling the getCode() method of Movie from the switch in statement(). (Or if there is a better way to do it, let me know.)</p> <pre><code>class Movie { private $title; private $code; public function __construct($title, $code) { $this->title = $title; $this->code = $code; } public function getCode() { return $this->code; } public function getTitle() { return $this->title; } } class Rental { private $movie; // will carry a Movie object private $days; public function __construct(Movie $movie, $days) { $this->movie = $movie; $this->days = $days; } public function getMovie() { return $this->movie; } } class Customer { private $name; private $rentals; // will be a collection of Rental Objects public function __construct($name) { $this->name = $name; } public function addRental(Rental $rental) { $this->rentals[] = $rental; } public function statement() { $thisAmount = 0; foreach ($this->rentals as $each) { // what is the better way to call this value?????? switch ($each->movie->code) { case 1: $thisAmount+= ($each->days - 2) * 1.5; break; case 2: $thisAmount += $each->days * 3; break; case 3: $thisAmount += 1.5; break; } // show figures for this rental $result = "\t" . $each->movie->title . "\t" . $thisAmount . "\n"; } return $result; } } // pick a movie $movie = new Movie('Star Wars', 0); // now rent it $rental = new Rental($movie, '2'); // now get statement $customer = new Customer('Joe'); $customer->addRental($rental); echo $customer->statement(); </code></pre>
