Command in PHP
Command is behavioral design pattern that converts requests or simple operations into objects.
The conversion allows deferred or remote execution of commands, storing command history, etc.
Usage of the pattern in PHP
Usage examples: The Command pattern is pretty common in PHP code. It’s used for queueing tasks, tracking the history of executed tasks and performing the “undo”.
Identification: The Command pattern is recognizable by behavioral methods in an abstract/interface type (sender) which invokes a method in an implementation of a different abstract/interface type (receiver) which has been encapsulated by the command implementation during its creation. Command classes are usually limited to specific actions.
