这里为啥用xml来实现呢
亲爱的李炎恢老师，正在做你的php第二季中的实战部分第44讲，在这一讲中有一个逻辑思路不解！
你以前的部分全是用的mysql数据库配合php写的，可是为啥到这里（新增会员），突然用xml来实现呢。不是说xml因为太臃肿被淘汰了吗？还有，为啥你这里不用mysql来实现呢。此中肿肿，大惑不解啊，能不能说说，谢谢
------解决思路----------------------
如果数据量不大的话，XML本身可以作为小型数据库来使用的，比如存放四六级单词之类的，用x-path解析，速度还是可以的。

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.
