网页开发与socket
本人学过php，做过类似网上购物这样的网站
最近在看协议方面的东西，接触了socket tcp/ip协议之类的东西
如果我没有理解错的话，socket就像是一个api函数包，用这个包可以实现tcp和udp协议
那么我的问题是：当我们用php做一个网站的时候，比如涉及到服务器和客户端交互信息的时候，是用什么协议实现的？是类似http协议这样的最高层的协议吗？是不是这里和tcp这样的协议没有什么直接的关系？？
谢谢～～
------解决思路----------------------
是的，与 tcp 协议没有直接的关系
tcp/ip 是底层通讯协议
socket 是 tcp/ip 的包装
http 构建与 socket 之上

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.
