PHP网页设计一段php代码：备份、恢复sql数据库（支...

掌握静态网页的制作技术是学习开发网站的先决条件，这一点就讲到这里，因为这篇文章不是教程文章，也就不对技术进行深入的刨析了。备份|恢复|数据|数据库   PHP代码:--------------------------------------------------------------------------------

  咱们就开始学习动态语言的概念吧，刚一接触动态语言，可能很多人都会蒙了，怎么这乱七八糟的东西，在网页里显示的时候却是另外一码事?其实这并不算乱七八糟，你写的HTML代码不也一样是一堆堆的字符吗?毕竟，代码并不是作为直接输出的，而是经过处理的，说白了，HTML是经过HTML解析器，而PHP当然也就通过PHP解析器了，跟学习HTML一样的道理，想让任何的解析器完成操作，就必须使用它们专用的语法结构，所以PHP长相奇怪也就不足为奇了。

php是动态网站开发的优秀语言，在学习的时候万万不能冒进。在系统的学习前，我认为不应该只是追求实现某种效果，因为即使你复制他人的代码调试成功，实现了你所期望的效果，你也不了解其中的原理。

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

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  \\\\\\\'_\\\\\\\' ;

这些都是最基本最常用功能，我们这些菜鸟在系统学习后，可以先对这些功能深入研究。

当留言板完成的时候，下步可以把做1个单人的blog程序，做为目标，

首推的搜索引擎当然是Google大神，其次我比较喜欢 百度知道。不过搜出来的结果往往都是 大家copy来copy去的，运气的的概率很大。

有时候汉字的空格也能导致页面出错，所以在写代码的时候，要输入空格最好用引文模式。

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。

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）。

兴趣是最好的老师，百度是最好的词典。

写的比较杂，因为我也是个新手，不当至于大家多多指正。

使用 jquery 等js框架的时候，要随时注意浏览器的更新情况，不然很容易发生框架不能使用。

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，

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。
