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.
