一周内PHP入门的根本步骤
一周内PHP入门的基本步骤
一周的时间就可以入门!
是的,对于已经有基于 、.NET等目标指向语言,WEB开发工作经验的人而言,PHP的入门时间一周足够,最多也不需要超过两周。
在这里,笔者绝对不是在哗众取宠,而是个人的亲身体验和身边同事的经验。
看到有人发贴说不会PHP,但是却被录用开发PHP,个人感觉这是很正常的。
对于有开发经验的人如何快速入门PHP,以下是我个人总结的一些经验供大家参考。
- 前提:
?? 1. 理解HTTP通信协议
????? 这一点非常重要,因为无论技术如何翻新,基础的内容是不会变的。例如HTTP通信协议,这是开发WEB程序的前提,PHP也是如此。
?? 2. 理解程序语言的基础知识
????? 无论什么语言,语法不尽相同但是编译原理、算法等知识都是相同的。
?? 3. 理解程序+数据库的基本原理
?? 4. 理解目标指向的编程思想
????? 虽然不是所有的PHP程序都是MVC,但是,发展趋势是PHP越来越像Servlet,甚至包括程序的编译和垃圾管理机制。
?? 5. 理解三层构架的基本思想
?? 6. 如果可能,理解Linux/Unix的一些常识
????? 虽然PHP主要是用来开发Web程序的语言,但是,它诞生于Linux/Unic,至今很多函数的使用习惯还是沿用来自于C语言的思想。
- 步骤:
????? 以下是具体的学习步骤。
?? 1. 根据公司的操作系统环境配置自己的学习环境。例如,Linux的版本、PHP的版本等等。
????? 由于很多商业服务器对环境要求比较苛刻,很少用rpm包安装服务器软件。特别是这种时候,尽可能构建与公司相同的环境就变得非常重要。而且,对于不熟悉 Linux/Unix的人来说,这也是一个熟悉Linux/Unix操作系统的一次机会。自己体验一下编译、安装的过程,一旦系统出现问题不会一头雾水,不知从何处下手。
?? 2. 选择一个比较好的开发工具。个人推荐Eclipse的PDT,可以从官方下载到all-in-one。
?? 3. 理解官方文档的查阅方法。
????? 写PHP程序根写 程序是一样的,没有开发手册是无法进行开发的。甚至包括基本的语法知识,都可以参考手册。
????? 可惜,PHP最新版手册官方还没有出中文,如果是在E文没有自信,可以从这里下载,以备一时之需(支持PHP4/5)。
?? 4. 自己写一个小程序,如BBS之类。注意按照公司内部的习惯去编程,完全可以照葫芦画瓢。
????? 写完之后,对PHP的语法基本上就理解的差不多了。
?? 5. 读工程代码。尽可能做到理解每一个步骤。对于大工程这一点很难做到,但是一定要理解框架的运行步骤,知道XX部分都是在干什么的。
呵呵,以上就是我个人的亲身体会,请高人指正。
