Prototype Design Pattern

The prototype pattern is used when the type of objects to create is determined by a  prototypical instance, which is cloned to produce new objects. This pattern is used to:

• avoid subclasses of an object creator in the client application..
• avoid the inherent cost of creating a new object in the standard way (e.g., using the 'new' keyword) when it is prohibitively expensive for a given application.

<?php
	Class Book {
	private $title = '';
	public function setTitle($title) {
	$this->title = $title;
	}
	public function getTitle() {
	return $this->title;
	}
	public function __clone() {}
	}
	$newBook = new Book();
	$newBook->setTitle("oops");
	$title = $newBook->getTitle();
	echo $title;
	echo "<br>";
	$newBook2 = clone $newBook;
	$newBook2->setTitle("designPattern");
	$title = $newBook2->getTitle();
	echo $title;
	echo "<br>";
	$newBook3 = $newBook;
	$newBook3->setTitle("newTittle");
	echo $newBook->getTitle();
	?>
