Advanced PHP developers have to master the skills that Swoole exists,
Whether it’s high concurrency or distributed or Swoole, it’s a tag for PHP advanced technologists, is also the standard line for identifying developer levels.
Why is Swoole viewed at such a high level?
What are its own characteristics?Today, I’m going to take you through the Swoole technology, looking beyond the phenomenon to the essence, and laying a solid foundation for future advanced learning.
Swoole is not as hard to learn as beginners might think. Swoole is a web application development tool that supports Http, TCP, UDP, WebSocket, and is described in the Encyclopedia as a “PHP asynchronous web communication engine for production environments.”
The PHP language is “easy to get started and easy to learn,” so it is often the programming language of choice for beginners. However, PHP is also a highly controversial language. On the one hand, PHP has the characteristics of fast development and low cost. It takes into account both PC website development and mobile APP development. PHP, on the other hand, has been criticized for “poor performance,” which is often used to question the future of PHP.
Swoole, with its introduction, solves PHP’s “poor performance” problem, making PHP the second most used language on projects. Until now, mastery of the PHP+swoole framework has been a necessary skill on the road to advanced PHper and is often used in project development.
Swoole has three features that make PHP’s high-performance microservices architecture a reality.
1. Resident memory to avoid performance loss caused by repeated loading and improve mass performance;
Traditional PHP frameworks need to load the framework file and configure it before each request is processed. Swoole doesn’t have this problem, loading it once and using it multiple times.
2. Coroutine asynchrony to improve the concurrent processing capability of I/O intensive scenarios;
Processes and threads are the basis of coroutines. Processes consume a lot of resources, so creating a process is not worth the cost. Once more threads are created, there will be a loss in thread scheduling.
Coroutines are implemented on a single-threaded basis to maximize CPU resources. Creating the same request consumes relatively few resources compared to processes and threads. The system automatically suspends the coroutine and transfers the CPU to other coroutines. In this way, the CPU utilization of a single thread is improved and the performance is improved.
Third, develop Http, WebSocket, TCP, UDP and other applications to communicate with hardware.
Above is my understanding use Swoole framework part, more detailed content can focus on my zhihu yaezakura PHP column or click here to join my official group, we will be in the form of a live online, professional and technical, the interpretation of lecturer let everybody for the integrated use of PHP and Swoole, can enter the deep understanding and mastery.
This course is an introductory course for Swoole. It introduces swoole installation to Swoole-TCP, synchronous client, asynchronous client, UDP, server client and other skills. At the same time, each summary theory is matched with practical cases of relevant commercial projects, so as to increase the learning effect and achieve mastery and use.
