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。

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
