This article mainly introduces the introduction of Swoole in the study of Swooled. It has a certain reference value. Now I share it with everyone. Friends in need can refer to it.
I have been working for a while, and occasionally You will hear swoole, and even if you are a PHP novice like me, you will think it is awesome even if you take a cursory look at the documentation. Due to the high cost of learning, I don’t know much about network asynchronous network communication.The document is not very friendly to novices. It is inevitable to stumble on the way to learn swoole, so I want to write some experience to benefit phper
But swoole is already a must-learn technology for PHP programmers. If you don’t know swoole, you can’t be considered an excellent PHP programmer.
I accidentally saw Mr. Singwa’s new textbook. It can be said that This is probably the best swoole tutorial on the Internet (the link will be attached later), so I still want to share my experience with you here.
swoole is not a framework, swoole is a high-performance extension of php written in c by Han Tianfeng, and SwooleFramework is a php framework written based on swoole. In addition, there are easyswoole
php's existing application methods. It is based on http and is relatively weak for situations that require fast real-time response. For example, online games or push services generally need to maintain a long-term TCP connection with the user in order to respond and push information in real time. (Personal understanding)
swoole is designed to solve such application scenarios.
You need to be proficient in PHP, and have both the basics of linux and redis
(1) A very important point to understand: the difference between TCP, UDP, HTTP, SOCKET, and WebSocket
(2) Read each case in the document once and try to use it once
(3) Combine the document with others and read each case How to write a project
(4) Finally, it is your own practice
Ps: Be sure to read more documents. If you don’t understand the suggestions, you should buy this set of courses and read them together for better results.
(1) Version support:
swoole 1.8.7 or higher is fully compatible with PHP7
Starting from version 2.0.12No longer supports PHP5
(2) The Linux distribution recommended by the system does not support window. Window developers can build a Linux environment through vm.
Sorted out the commonly used swoole Command
(a) php file name.php execution program
(b) ctrl c force exit program
(c) telnet 127.0.0.1 port number tcp connection service test
(d) netcat 127.0. 0.1 Port number UDP server connection test
(e) netstat -an | grep port view port, the occupied port will not be used
(f) ps -an|grep file name to view the process (you can also Look at the number of threads)
(g) kill -9 pid kills the process

There are two ways to install 1. Compile and install 2.PECL (a relatively brainless installation method)
It is recommended to use compile and install, which is more conducive to learning
How to check whether the installation has been successful?
php -m Check whether the swoole extension has been installed
After installing swoole, we can happily use swoole^-^
