求PHP学习速成法
本人学PHP已经有几个月了,现在已经开始阅读一些框架模板,问题出现了,比如在看smarty,和biweb的时候,有时候看的比较凌乱,没有一个整体的思路。也就是说我只能看懂一个一个函数是什么意思而不清楚整个文件起一个什么作用。谁能告诉我写看源代码的经验啊,
还有smarty的源码解释,最好是注释中文版的,我看到里面的注释大多都是英文的。谢谢。。。
------解决方案--------------------
以 smarty 为例
smarty 是模板引擎,它具有自己的模板语言
模板文件存放于 template 中
预编译文件存放于 template_c 中
将模板文件与预编译文件对比,就可知道模板的各个成分被翻译成了什么
在 smarty。php 中搜索预编译文件中的某些关键字,就可以知道什么方法在处理什么语法结构
smarty 是有中文文档的

静下心来 多写些基础的部分.然后再去看相同的部分别人是如何写的,这样代码也能看得懂 也能知道别人是如何巧妙的构造.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
