一个简单的模板类(PHP)
接上话,有了一个数据操作类,这样项目只能简单地操作数据,但是要达到能够和美工一起显示美好的页面,则需要一个比较好的模板引擎。与SMARTY这样比较庞大的模板引擎相比,我想下面这个则真算得小得多了。
这个模板类是我以前在网上看到的,写得比较好,所以我就引用了,还不知道作者是谁,这里就先讲一下这个类的原理。
首先,这个类只有一个简单的正则解析器。但是基本上可以用到了。如果再能够在此基础上扩展,我相相信这个小东西很有发展,请有相同爱好的同志们,来加入到强化他的目地。我这就抛下砖。
template.class.php
有了这个模板,你可以忘记那些大型的模板,毕竟你的美工不会在他的切片文件里写那么多SMARTY的标记,而只要他切好,你可以直接用,不用去修改images , css ,js 地址了。

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.
