最近开始接触 MVC 结构开发方式,在选 MVC 框架上我比较偏向于不需要复杂配置的框架.

找了一阵,看中了 2 个网上比较火的框架: CodeIgniter & CakePHP.

2 个都是只需要简单配置就可以开始使用的框架,类库和函数库(Helper)都很丰富,大大增快开发效率. (比我写的类库强 )



CakePHP 看起来比好像比 CodeIgniter 复杂,中文文档也不多,网上也有反映 CakePHP 过于复杂而导致执行效率降低,最后选了 CodeIgniter, 不过比较喜欢 CakePHP 的 Logo.

关于 MVC 模式这里有一篇介绍文章: http://www.ibm.com/developerworks/cn/linux/sdk/php/php_design/index.html#3
