How to implement multi-threading in PHP?

PHP Multi-threading refers to running multiple tasks at the same time in a process, which is achieved by creating independently running threads. You can use the Pthreads extension in PHP to simulate multi-threading behavior. After installation, you can use the Thread class to create and start threads. For example, when processing a large amount of data, the data can be divided into multiple blocks and a corresponding number of threads can be created for simultaneous processing to improve efficiency.

What is multi-threading?

Multi-threading refers to the ability to run multiple tasks simultaneously in a process. This can be achieved by creating lightweight processes (threads), each of which can run independently.

Multi-Threading in PHP

PHP does not currently support native multi-threading. However, we can use extension libraries such as Pthreads or Threaded to simulate multi-threaded behavior.

Use Pthreads to implement multi-threading

Install Pthreads:

pecl install pthreads

Create threads:

<?php
use Pthreads\Thread;

$thread = new Thread(function () {
    // 线程代码
});

Start the thread:

$thread->start();

Wait for the thread to complete:

$thread->join();

Practical case:

Suppose we have a file containing a large amount of data to be processed. We can use multi-threading to process this data simultaneously to improve efficiency.
