How to catch php errors with swoole
Once a fatal error occurs during the running of swoole_serverServer, the client connection will not be responded to.
For example, a web server, if there is a fatal error, an HTTP 500 error message should be sent to the client. (Recommended study: swoole video tutorial)
In PHP, fatal errors can be captured through register_shutdown_function error_get_last 2 functions, and the error information is sent to the client connection.
The specific code examples are as follows:
register_shutdown_function('handleFatal'); function handleFatal() { $error = error_get_last(); switch ($error['type'] ?? null) { case E_ERROR : case E_PARSE : case E_CORE_ERROR : case E_COMPILE_ERROR : $message = $error['message'] . PHP_EOL; if (isset($_SERVER['REQUEST_URI'])) { $message .= '[QUERY] ' . $_SERVER['REQUEST_URI']; } // log or send: // error_log($message); // $server->send($fd, $message); break; } }

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

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.

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.

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 Process allows users to switch. The specific steps are: create a process; set the process user; start the process.

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.

Swoole is a high-performance PHP network development framework. With its powerful asynchronous mechanism and event-driven features, it can quickly build high-concurrency and high-throughput server applications. However, as the business continues to expand and the amount of concurrency increases, the CPU utilization of the server may become a bottleneck, affecting the performance and stability of the server. Therefore, in this article, we will introduce how to optimize the CPU utilization of the server while improving the performance and stability of the Swoole server, and provide specific optimization code examples. one,

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
