At work, I also learned that Pack,unpack,ord is powerful for binary byte processing. Let me introduce them to you. In our work, there is not much estimation of their use. I am in a recent job, because the communication needs to use the binary stream, and then the interface is received in PHP. At that time, a lot of information was consulted. Because they are really less used, they are seldom used by friends in their work. At work, I also learned that
