PHP Design Patterns - Cheatsheet

MVC (Model-View-Controller)

• Organizes entire project
• Splits thinking process (3 thinking hats?)

Problem:

All logic is done all over place

Solution:

Model - Data and business logic

Controller - Flow and data control (?)

View - Presentational logic

Singleton

• Single instance of object/class for entire project
• Similar to superglobals

Problem:

ex. databases and files allows single connection per resource

Solution:

Singleton always returns same resource

Example:

Email::sendEmail($email, $message);

Log::error($errorString)
