What is swoole used for?
Swoole is an asynchronous multi-threaded server written in C language and supports PHP language. Its functions include asynchronous TCP/UDP network client, asynchronous MySQL, asynchronous Redis, and database connection pool , AsyncTask, message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query, etc.
Swoole has built-in Http/WebSocket server/client and Http2.0 server.
Swoole can mainly be used to solve long-time-consuming tasks. There is no concept of process or thread in PHP. However, swoole can be used as an extension of PHP to use processes and threads, and can be used to solve concurrency problems.
Secondly, there is a Websocket service in the swoole framework, which can be used to implement online IM systems and chat room functions;
can also be used to solve some scenarios that require timing functions.
What can swoole do?
1. Used for sending emails, broadcasts, and scheduled tasks; swoole supports asynchronous task functions, so it can be used to push some emails and broadcasts; secondly, it has a millisecond timer, which can be combined with The function of asynchronous tasks is to send scheduled tasks, imitating the crontab tasks in Linux.
2. The transmission function of positioning function; for example, when ordering takeout, the moving position of the map during the delivery process of the delivery person can be used to obtain the information of the delivery person asynchronously in real time.
3. Development of IM system and chat room functions; swoole has Websocket server function. After the front end sends information to the client, the server can accurately push the message to the other end, thereby achieving real-time communication.
4. System monitoring function; it can asynchronously record the data requested by http and monitor each request of the system.

How to use swoole coroutine in laravel
Apr 09, 2024 pm 06:48 PM
Using Swoole coroutines in Laravel can process a large number of requests concurrently. The advantages include: Concurrent processing: allows multiple requests to be processed at the same time. High performance: Based on the Linux epoll event mechanism, it processes requests efficiently. Low resource consumption: requires fewer server resources. Easy to integrate: Seamless integration with Laravel framework, simple to use.
How to use Swoole to implement a high-performance HTTP reverse proxy server
Nov 07, 2023 am 08:18 AM
How to use Swoole to implement a high-performance HTTP reverse proxy server Swoole is a high-performance, asynchronous, and concurrent network communication framework based on the PHP language. It provides a series of network functions and can be used to implement HTTP servers, WebSocket servers, etc. In this article, we will introduce how to use Swoole to implement a high-performance HTTP reverse proxy server and provide specific code examples. Environment configuration First, we need to install the Swoole extension on the server
How to restart the service in swoole framework
Apr 09, 2024 pm 06:15 PM
To restart the Swoole service, follow these steps: Check the service status and get the PID. Use "kill -15 PID" to stop the service. Restart the service using the same command that was used to start the service.
Which one is better, swoole or workerman?
Apr 09, 2024 pm 07:00 PM
Swoole and Workerman are both high-performance PHP server frameworks. Known for its asynchronous processing, excellent performance, and scalability, Swoole is suitable for projects that need to handle a large number of concurrent requests and high throughput. Workerman offers the flexibility of both asynchronous and synchronous modes, with an intuitive API that is better suited for ease of use and projects that handle lower concurrency volumes.
Which one has better performance, swoole or java?
Apr 09, 2024 pm 07:03 PM
Performance comparison: Throughput: Swoole has higher throughput thanks to its coroutine mechanism. Latency: Swoole's coroutine context switching has lower overhead and smaller latency. Memory consumption: Swoole's coroutines occupy less memory. Ease of use: Swoole provides an easier-to-use concurrent programming API.

Swoole in action: How to use coroutines for concurrent task processing
Nov 07, 2023 pm 02:55 PM
Swoole in action: How to use coroutines for concurrent task processing Introduction In daily development, we often encounter situations where we need to handle multiple tasks at the same time. The traditional processing method is to use multi-threads or multi-processes to achieve concurrent processing, but this method has certain problems in performance and resource consumption. As a scripting language, PHP usually cannot directly use multi-threading or multi-process methods to handle tasks. However, with the help of the Swoole coroutine library, we can use coroutines to achieve high-performance concurrent task processing. This article will introduce
How is the swoole coroutine scheduled?
Apr 09, 2024 pm 07:06 PM
Swoole coroutine is a lightweight concurrency library that allows developers to write concurrent programs. The Swoole coroutine scheduling mechanism is based on the coroutine mode and event loop, using the coroutine stack to manage coroutine execution, and suspend them after the coroutine gives up control. The event loop handles IO and timer events. When the coroutine gives up control, it is suspended and returns to the event loop. When an event occurs, Swoole switches from the event loop to the pending coroutine, completing the switch by saving and loading the coroutine state. Coroutine scheduling uses a priority mechanism and supports suspend, sleep, and resume operations to flexibly control coroutine execution.
