Bcosca/fatfree. Five common PHP design patterns. Editor's note: See the follow-up article "Five more PHP design patterns" to learn about five additional design patterns that you might find useful.
Design patterns were introduced to the software community in Design Patterns, by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (colloquially known as the "gang of four"). The core concept behind design patterns, presented in the introduction, was simple. Over their years of developing software, Gamma et al found certain patterns of solid design emerging, just as architects designing houses and buildings can develop templates for where a bathroom should be located or how a kitchen should be configured. Having those templates, or design patterns, means they can design better buildings more quickly. The same applies to software. Using PHP and XSL to Transform XML into Web Content.
