DevShed concludes their look at the Flyweight pattern with this new tutorial - the second part focusing on building an actual application with the pattern implemented.
In this final part of the series, I'm going to teach you in a step-by-step format how to create in PHP 5 a flyweight class to balance the instantiation of objects that will be used to generate web documents on the fly. Hopefully, by the end of this article, you should have acquired a considerable background in how to apply the flyweight pattern in a real-world situation.
They create a simple application that generates dynamic HTML elements - DIV tags - with a simple interface to define things like content, name, and ID. Their Flyweight factory class creates and manages the number of DIVs that are created, blocking requests for any more. Finally, they apply it, showing the creation of a simple web page with multiple DIVs in it.
