Pretty much sums up how I feel about most of the big frameworks (Zend in particular, but also Symfony and CakePHP). The problem of over-engineering isn't just related to the big PHP frameworks - the same problem exists in Python and Ruby. At its core, web development is about taking some user input, validating it, throwing it in a database, and displaying it again (perhaps slightly modified) to users. That's a fairly…

Frameworks are also very useful. They can provide a tested database layer that prevents SQL injection, form data validation and escaping, straight-forward MVC structure, and a library of common functions that are well tested and help developers avoid common mistakes.

Ideally, a framework would have some basic elements and then additional components that can be included if required by a project but aren't core to the framework.

What if I need to add 2 and 1? Is there a lib for that? Or would this one need to be completely refactored? Also, in what version could we expect ability to handle 2 digit (or more!) numbers?

The library supports adding other numbers than 1 and 1. Your use case of adding 2 to 1 is supported. As are multi-digit numbers. As are negative numbers.

As you can see, the library is quite advanced.

What? No dependency injection framework? Pft! :)

There's a pull request for that now. ;-)

All web solutions use pluggable middleware ( Ruby Rake , Python WSGI , NodeJS Connect ). So PHP getting some abstraction is JAVA-ISH ?

What about subtraction now?

Negative numbers are supported. But if you want a clean solution, implementing a SubtractionOperator is easy enough. Just implement the OperatorInterface.

The only flaw I can see is that the string literal '1' should have been declared as a const somewhere, preferably in another unrelated library, and called something like 'UNITY_VALUE'.

On the note of that, there should really be a SimpleNumberFactory.

I notice that all of those things are internally simple. No bloat required.

The functional unit tests made me laugh: https://github.com/Herzult/SimplePHPEasyPlus/blob/master/tes...

What!? No mock classes?

All of the classes in this were created for the purpose of mockery.

You know, planes are a very simple concept: something that flies. Aerospace engineering should reflect that.

Reminds me of something I wrote a few months ago on how to detect negative numbers: http://stackoverflow.com/a/11910993/1329367 but obviously the one above has much more value add and follows better design patterns.
