Solutions for concurrent programming in the PHP framework include: 1. Multi-process: Create independent processes and schedule them by the operating system; 2. Multi-threads: Create threads in a shared address space and schedule them directly by PHP; 3. Coroutines: A lightweight thread whose execution is controlled by a coroutine library. When choosing an appropriate solution, you should consider the resource consumption, performance requirements, and concurrency scale of the task.
Solutions to concurrent programming in the PHP framework
The meaning of concurrency
Concurrent programming allows multiple tasks to be executed simultaneously, thereby maximizing utilization of CPU and memory resources. This is critical for handling large numbers of requests or computationally intensive tasks.
Concurrent programming in PHP framework
The following are some solutions for concurrent programming in PHP framework:
1. More Process
Features:
Practical case:
<?php // 创建多个子进程 $processes = []; for ($i = 0; $i < 4; $i++) { $pid = pcntl_fork(); if ($pid > 0) { // 父进程保存子进程 ID $processes[] = $pid; } else if ($pid === 0) { // 子进程执行任务 // ... } } // 父进程等待子进程完成 foreach ($processes as $pid) { pcntl_waitpid($pid, $status); } ?>
2. Multi-threading
Features:
Practical case:
<?php // 使用 pthreads 库创建线程 use Pthreads\Thread; $thread = new Thread(function () { // 线程任务 // ... }); // 启动线程 $thread->start(); // 等待线程完成 $thread->join(); ?>
3. Coroutine
Features:
Practical case:
<?php // 使用 Swoole 协程库 use Swoole\Coroutine; Coroutine::create(function () { // 协程任务 // ... });
