近几年来,随着PHP作为一门被许多开发者选作他们的脚本语言而不断演化,PHP开发框架如雨后春笋般走上荧屏。人们总是在争吵到底哪个PHP开发框架最好,但不是每个框架都是为所有人而产生的,这本来是很简单的事实。这里列举五个最好的最受欢迎的PHP开发框架:
The Zend Framework
The Zend Framework 在开发社区中有大量的追随者,它致力于Web 2.0风格的程序。因为它众多的追随者组成的活跃用户开发的扩展支持,Zend被称为“The PHP Company”。Zend是一个,也可能不是,今天可用的最受欢迎的PHP开发框架。它有健壮的特征能够支持协作开发,它需要一些PHP的额外知识。
CakePHP
CakePHP 无论对于初学者还是职业PHP开发者都是很好的选择。它基于与Ruby on Rails同样的原则而设计,它十分注重快速开发——这使得它成为一个非常好的用于RAD的开发框架。它快速增长的支持系统,简洁性和可测量性使得CakePHP成为今天可用的最受欢迎的PHP开发框架之一。
Symfony
Symfony 是为那些更加职业的主要开发企业级程序的开发者而准备的——特别是 Askeet 和 Yahoo! Bookmarks。这款开源PHP开发框架有着丰富的特性,做起这些来绰绰有余,它主要的缺点是比其他的框架略微慢一些。

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
