PHP网页编程之一个很适用亲睦用的资本办理器的树形目...

在学习PHP这六个月里，每看到一个优秀的php脚本，就会兴奋的手舞足蹈，嘴里还不停的说：太酷了，太酷了。呵呵，很幼稚吧，但这可能就是兴趣。   来源根基码从网高低载，经自己改写，功效更壮大，利用更便利，可以有没有限级目次，一次性载入，可以分离设置树结点和叶结点的色彩及图标，可以睁开和压缩，可以显示以后所处的途径地位，点击树结点时只在睁开时显示树结点的超链接，不外，据测试，一次性载入500个节点时阅读器会显示“该剧本会使阅读器变慢”的提醒，不外，选择不作废履行不会影响阅读器的功能。

培训的第一阶段，学习的是HTML/CSS/JavaScript基础。

遇到出错的时候，我经常把错误信息直接复制到 google的搜索栏，一般情况都是能搜到结果的，不过有时候会搜出来一大片英文的出来，这时候就得过滤一下，吧中文的弄出来，挨着式方法。

当然这种网站的会员费就几十块钱。

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。

作为一个合格的coder 编码的规范是必须，命名方面我推崇“驼峰法”，另外就是自己写的代码最好要带注释，不然时间长了，就算是自己的代码估计看起来都费事，更不用说别人拉。

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。

爱上php，他也会爱上你。

写的比较杂，因为我也是个新手，不当至于大家多多指正。

仓酷云

其实没啥难的，多练习，练习写程序，真正的实践比看100遍都有用。不过要熟悉引擎

学习php的目的往往是为了开发动态网站，phper就业的要求也涵盖了很多。我大致总结为：精通php和mysql

真正的方向了，如果将来要去开发团队，你一定要学好smarty ,phplib这样的模板引擎，

环境搭建好,当你看见你的浏览器输出“it works\\\\\\\"时你一定是喜悦的。在你解决问题的时候，我强烈建议多读php手册。

曾经犯过一个很低级的错误，我在文件命名的时候用了一个横线\\\\\\\'-\\\\\\\' 号，结果找了好几个小时的错误，事实是命名的时候 是不能用横线 \\\\\\\'-\\\\\\\' 的，应该用的是下划线  \\\\\\\'_\\\\\\\' ;

开发工具也会慢慢的更专业，每个公司的可能不一样，但是zend studio是个大伙都会用的。

小鸟是第一次发帖（我习惯潜水的(*^__^*) 嘻嘻……），有错误之处还请大家批评指正，另外，前些日子听人说有高手能用php写驱动程序，真是学无止境，人外有人，天外有天。

在学习的过程中不能怕麻烦，不能有懒惰的思想。学习php首先应该搭建一个lamp环境或者是wamp环境。这是学习php开发的根本。虽然网络上有很多集成的环境，安装很方便，使用起来也很稳定、

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。
