Many frameworks are based on mvc, but I have no idea about MVC. So what is the use of MVC? Is it for speed, security or any other reason?
MVC允许您将业务逻辑与表示层分离。这种“关注点分离”允许您快速查找和编辑代码的部分。它还可以在整个系统中方便地重用UI组件。
查看wiki页面，了解MVC的过度学术和技术介绍http://en.wikipedia.org/wiki/Model_view_controller
MVC主要是为了提高代码的可维护性。通过将数据库逻辑与表示逻辑与控制器逻辑分离，您可以更容易地进行更改/重写/维护。
it also solves the problem of "spaghetti code", you can outsorce your HTML/XML/PDF/XSL creation Code to your View/Template engine, get the Data from Your Model(DB/File/RemoteCall,...) and your Controller controls the behaviour of Both, you can also simply exchange the View/Models without even Change the Controller if u implement it right, so you gain Seperation of Concerncs, get better Code & Maintainability and can easily swap components also its easier to manage if your projects grow. I recommend the Usage of a FrontController which selects the right Controller for you depending on the Users input, you can also use Inversion of Control/DependencyInjection Pattern there and let your Controller be configued by your FrontController / Pass DB Connection and lots of lots of lots more funny stuff Now u got a simple application framwork:) Use Zend Instead:)
