PHP编程：用php5轻松解析xml

我的文章不会对您的学习起到实质性的作用，您能否成功，还得靠自己的，坚持，坚持，再坚持，就是步入成功的不二法门。php5|xml   用sax体例的时分,要本人构建3个函数, 并且要直接用这三的函数来前往数据, 请求较强的逻辑. 在处置分歧布局的xml的时分, 还要从头停止机关这三个函数,费事!
用dom体例,却是好些,然而他把每一个节点都看做是一个node, 操作起来要写很多多少的代码, 费事!
网上有很多多少的开源的xml解析的类库, 之前看过几个, 然而心里老是感觉不扎实, 感到老是跟在他人的屁股前面.
这几天在弄java, 挺累的, 所以决意换换脑壳, 写点php代码, 为了避免今后xml解析进程再令我犯难, 就花了一天的工夫写了上面一个xml解析的类, 因而就有了上面的器材,
完成体例是经由过程包装"sax体例的解析了局"来完成的. 总的来讲，关于我团体来讲挺适用的，功能也还可以，根基上可以完成大多半的处置请求。
功效:
1\ 对根基的xml文件的节点停止 查询 / 添加 / 修正 / 删除 任务.
2\ 导出xml文件的一切数据到一个数组外面.
3\ 全部设计采取了oo体例,在操作了局集的时分, 利用办法相似于dom
弱点:
1\ 每一个节点最好都带有一个id(看前面的例子), 每一个“节点名字”=“节点的标签_节点的id”，假如这个id值没有设置，法式将主动给他发生一个id，这个id就是这个节点在他的下级节点中的地位编号，从0入手下手。
2\ 查询某个节点的时分可以经由过程用“|”符号毗连“节点名字”来停止。这些“节点名字”都是按按次写好的下级节点的名字。
利用申明：
运转上面的例子，在履行了局页面上可以看到函数的利用申明

代码是经由过程php5来完成的，在php4中没法正常运转。
因为方才写完，所以没有收拾整顿文档，上面的例子演示的只是一局部的功效，代码不是很难，如果想晓得更多的功效，可以研讨研讨源代码。

毕业设计作品自己个人还是觉得比较满意的，尽管有些功能考虑的不全面，也没有很好的实现。

建议加几个专业的phper的群，当然啦需要说话的人多，一处一点问题能有人回答你的，当然啦要让人回答你的问题，平时就得躲在里面聊天，大家混熟啦，愿意回答你问题的人自然就多啦。

个人呢觉得，配wamp 最容易漏的一步就是忘了把$PHP$目录下的libmysql.dll拷贝到windows系统目录的system32目录下，还有重启apache。

Apache不是非得用80或者8080端口的，我刚开始安得时候就是80端口老占用，就用了个 81端口，结果照常，就是输localhost的时候，应该输入为 localhost:81

说php的话，首先得提一下数组，开始的时候我是最烦数组的，总是被弄的晕头转向，不过后来呢，我觉得数组里php里最强大的存储方法，所以建议新手们要学好数组。

你很难利用原理去编写自己的代码。对于php来说，系统的学习我认为还是很重要的，当你有一定理解后，你可你针对某种效果研究，我想那时你不会只是复制代码的水平了。

这些中手常用的知识，当你把我说的这些关键字都可以熟练运用的时候，你可以选择自己

基础有没有对学习php没有太大区别，关键是兴趣。

如果你已经到这种程度了，那么你已经可以做我的老师了。其实php也分很多的区域，

Apache不是非得用80或者8080端口的，我刚开始安得时候就是80端口老占用，就用了个 81端口，结果照常，就是输localhost的时候，应该输入为 localhost:81

我要在声明一下：我是个菜鸟！！我对php这门优秀的语言也是知之甚少。但是我要在这里说一下php在网站开发中最常用的几个功能：

Apache不是非得用80或者8080端口的，我刚开始安得时候就是80端口老占用，就用了个 81端口，结果照常，就是输localhost的时候，应该输入为 localhost:81

对于懒惰的朋友，我推荐php的集成环境xampp或者是wamp。这两个软件安装方便，使用简单。但是我还是强烈建议自己动手搭建开发环境。

建数据库表的时候，int型要输入长度的，其实是个摆设的输入几位都没影响的，只要大于4就行，囧。

没接触过框架的人，也不用害怕，其实框架就是一种命名规范及插件，学会一个框架其余的框架都很好上手的。

有位前辈曾经跟我说过，phper 至少要掌握200个函数 编起程序来才能顺畅点，那些不熟悉的函数记不住也要一拿手册就能找到。所以建议新手们没事就看看php的手册（至少array函数和string函数是要记牢的）。

最后介绍一个代码出错，但是老找不到错误方法，就是 go to wc （囧），出去换换气没准回来就找到错误啦。

因为blog这样的可以让你接触更多要学的知识，可以接触用到类，模板，js ，ajax

写的比较杂，因为我也是个新手，不当至于大家多多指正。

为了以后维护的方便最好是代码上都加上注释，“予人方便，自己方便”。此外开发文档什么的最好都弄齐全。我觉得这是程序员必备的素质。虽然会消耗点很多的时间。但是确实是非常有必要的。
