我们的目的

现在有很多各种各样的PHP框架，但他们没有一个像Phalcon一样（真的，在这点上请相信我）

几乎所有的程序员都喜欢使用框架，这主要是因为框架提供了很多的功能，已经经过了大量的测试，因此保持代码DRY（不要重复造轮子）。然而，框架本身需要包含大量的文件来解释和执行实际应用中的每个请求，因此会降低应用程序的性能，影响用户体验。

The Question

为什么我们不能有这样一个框架，保持它的优势的同时，没有或者很少有缺点呢？

这就是为什么Phalcon诞生了！

在过去的几个月中，我们已经广泛地研究了PHP的行为，调查区域为显着优化（大或小）。 通过Zend引擎的理解，我们设法消除不必要的验证，压缩的代码，进行优化和生成的 低级别的解决方案，从而使Phalcon实现最大的性能。

Why?

• The use of frameworks has become mandatory in professional development with PHP
• 框架提供了结构化的理念，以轻松维护项目，编写更少的代码，使工作变得更有趣

Inner workings of PHP?

• PHP是一种动态的和弱变量类型语言。每次一个二进制运算（例如，2+“2”），PHP就会检查操作数的类型来进行类型转换
• PHP是解释型语言。主要的缺点是性能上的损失
• 每一个请求，它必须首先解释.
• 如果不使用字节码缓存（如APC），则任何时间的任何一个请求它都会进行语法检查

How traditional PHP frameworks work?

• Many files with classes and functions are read on every request made. Disk reading is expensive in terms of performance, especially when the file structure includes deep folders
• Modern frameworks use lazy loading (autoload) to increase performance (for load and execute only the code needed)
• Continuous loading or interpreting is expensive and impacts performance
• The framework code does not change very often, therefore an application needs to load and interpret it every time a request is made

How does a PHP C-extension work?

• C extensions are loaded together with PHP one time on the web server’s daemon start process
• Classes and functions provided by the extension are ready to use for any application
• The code isn’t interpreted because is already compiled to a specific platform and processor

How does Phalcon work?

• Components are loosely coupled. With Phalcon, nothing is imposed on you: you’re free to use the full framework, or just some parts of it as a glue components.
• Low-level optimizations provides the lowest overhead for MVC-based applications
• Interact with databases with maximum performance by using a C-language ORM for PHP
• Phalcon directly accesses internal PHP structures optimizing execution in that way as well

Conclusion

Phalcon is an effort to build the fastest framework for PHP. You now have an even easier and robust way to develop applications without be worrying about performance. Enjoy!
