使用MVC方法（基于PHP）的Web应用程序是否必然意味着它会比其他方法更具可伸缩性？

Question

据我了解，MVC框架相当庞大（Zend，Cake，CodeIngniter），因此似乎几乎与讨论可伸缩性并建议使用MVC背道而驰。

Answer 1

Zend, Cake, CodeIgniter... they all come with a bunch of stuff you don't need. A basic MVC framework is simple, and does not need many files to work.

Also, applications built upon a MVC structure are no more or less scalable than other approaches may be, but may be more organized. It's subjective.

Answer 2

Although the point of MVC is simple - having data access (Model), GUI creation (View) and flow control (Controller) as separate components - it can be implemented in very different ways.

From a purely technical viewpoint, MVC has very little to do with computational scalability. It's more about the human factor and having a way to organize huge piles of code into meaningful sub-units that are much easier to understand.

Answer 3

I work with codeigniter every day and compared to the others mentioned it's very light weight.

You have to consider that you will likely not use a lot of the functionality provided in the largest frameworks so just because the files are there, it's not necessarily heavy unless you include lots of the files in your actual executing code.

You can help make your own code scalable in these situations by considering when and when not to use functionality provided by the framework. Learn PHPs built in functions well as they will almost always be faster than anything in a framework (because they are written in C).

A good framework should really just help you structure you code and give you extra functionality when you ask for it, not lumber your application with a lot of extra processing.
