Among the several PHP homepage spaces that the author has applied for, there are not many that can provide mail functions. There is always nothing to do after calling the mail() function. But email plays a growing role in online life. Think about it, can an internet bug be called a real internet bug if he surfs the Internet without receiving emails? I don’t want to talk about the role of email anymore, but what should I do if the homepage space does not support mail() sending? I have also thought about sending emails through sockets, but unfortunately I am not familiar with socket programming using PHP. In addition, sending emails requires the SMTP protocol and requires reading a lot of English, so I have never studied it. Finally one day I found an article about using socket programming to send emails. I copied it as if I had found a treasure, and transformed it into a class available in PHP for everyone to use. The original article was just a simple example, and there were some errors. After many experiments and transformations, I finally changed it into a class that directly uses sockets to send emails to specified mailboxes. If you follow the previous instructions about sending By combining MIME articles, you can send emails on websites that do not support the mail() function. Because the process of sending emails takes time, it may not be exactly the same as the processing mechanism of mail(), so the speed is slower, but it can solve the urgent need to send emails. At the same time, you can also learn to use PHP for socket programming. Next, I will introduce the implementation principle of this class to you, and at the same time explain some basic knowledge about SMTP to you.
Introduction to Socket Programming
I would like to state to everyone that I am not a TCP/IP programming expert, so I am just sharing my understanding and experience here.
Use the fsockopen function to open an Internet connection. The function syntax format is:
int fsockopen(string hostname, int port, int [errno], string [errstr], int [timeout]);
The meaning of the parameters is: Needless to say, since the SMTP protocol is used here, the port number is 25. After the connection is successfully opened, a socket handle will be returned, which can be used like a file handle. Available operations include fputs(), fgets(), feof(), fclose(), etc.
That’s it for a very simple introduction.

一、基于TCP协议的socket套接字编程1、套接字工作流程先从服务器端说起。服务器端先初始化Socket,然后与端口绑定(bind),对端口进行监听(listen),调用accept阻塞,等待客户端连接。在这时如果有个客户端初始化一个Socket,然后连接服务器(connect),如果连接成功,这时客户端与服务器端的连接就建立了。客户端发送数据请求,服务器端接收请求并处理请求,然后把回应数据发送给客户端,客户端读取数据,最后关闭连接,一次交互结束,使用以下Python代码实现:importso

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),
