Laravel 1 included built-in support for authentication, localisation, models, views, sessions, routing and other mechanisms, but lacked support for controllers that prevented it from being a true MVC framework. [1] Laravel 2 was released in September 2011, bringing various improvements from the author and community.
The model is an interface defining the data to be displayed or otherwise acted upon in the user interface. The view is a passive interface that displays data (the model) and routes user commands to the presenter to act upon that data. The presenter acts upon the model and the view. It retrieves data from repositories (the model), and formats it ...
The controller is responsible for invoking business services and controlling the application's flow. When it is time to send the web response to the client, the controller sets a view template to be rendered, putting data in a special dictionary object known as the "Property Bag", and delegates the template rendering to a view engine.

Under inversion of control, the framework first constructs an object (such as a controller), and then passes control flow to it. With dependency injection, the framework also instantiates the dependencies declared by the application object (often in the constructor method's parameters), and passes the dependencies into the object.
Use cases include applications that surface private data hidden behind an authentication system.

A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly.

The controller responds to the user input and performs interactions on the data model objects. The controller receives the input, optionally validates it and then passes the input to the model. As with other software patterns, MVC expresses the "core of the solution" to a problem while allowing it to be adapted for each system. [38]
