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
回复讨论(解决方案)
xml文本，数据库，都是存储方式。
用哪个都可以，当然用数据库比较好。
可能例子是想指导如何用xml保存数据，及数据的读写吧。

好象不是这样，这个只有做站的人才能解释他当时的想法，也许当时他被逼无 奈，也许当时他迫不得已，也许他当时只会这个
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。
你应该给出教程的出处

你少来，我最怕装牛的人了，别吓唬我行不？
你在质疑教程的问题，却又不肯给出教程的内容
我怎么能知道教程的原意是什么？是否是你自己理解错了呢？
正因为不懂，所以才要去看教程
而不是随意地猜测作者的意图
