Swoole Learning - Introduction to Swoole

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.

1.What is swoole? What can this guy do?

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.

2. The basics required to learn swoole

You need to be proficient in PHP, and have both the basics of linux and redis
