Swoole and Workerman's optimization methods for local and remote caching of data in PHP and MySQL

Swoole and Workerman's optimization method for local and remote caching of data in PHP and MySQL requires specific code examples

With the development of the Internet, PHP and MySQL are used as As the main tool for developing web applications, its performance and efficiency issues have always been the focus of developers. In order to improve performance and reduce database pressure, developers usually use data caching to optimize applications. This article will introduce the optimization method of using two commonly used PHP extensions, Swoole and Workerman, for data local caching and remote caching, and give specific code examples.

First of all, let’s take a look at the basic concepts and usage of the two extensions, Swoole and Workerman.

Swoole is a high-performance network communication framework for PHP developers. It provides powerful asynchronous, concurrency, coroutine and other features, which can greatly improve application performance and concurrency capabilities.

Workerman is a multi-process asynchronous event-driven development framework based on PHP, which can implement high-performance TCP/UDP servers or clients. It is characterized by simplicity and ease of use, and can quickly build high-performance network applications.

Next, we will introduce in detail the optimization methods of Swoole and Workerman in data caching.

Optimization method for data local caching:
For some frequently accessed data, you can cache it in local memory to reduce frequent access to the database. The following is a sample code for using Swoole and Workerman for data local caching:

Using Swoole for data local caching:

<?php
// 创建一个内存表
$table = new swoole_table(1024);
$table->column('value', swoole_table::TYPE_STRING, 64);
$table->create();

// 设置缓存
$table->set('key1', ['value' => 'data1']);
$table->set('key2', ['value' => 'data2']);

// 获取缓存
$result = $table->get('key1');
echo $result['value']; // 输出：data1

Using Workerman for data local caching:

<?php
$cache = [];
$cache['key1'] = ['value' => 'data1'];
$cache['key2'] = ['value' => 'data2'];

// 获取缓存
$result = $cache['key1'];
echo $result['value']; // 输出：data1

Through the above In the sample code, we can see how to use Swoole's memory table and Workerman's array to implement the data local caching function.

Optimization method of data remote caching:
In addition to caching data locally, you can also cache data to remote cache servers, such as Redis, Memcached, etc. The following is a sample code for using Swoole and Workerman for data remote caching:

Using Swoole for data remote caching:

<?php
$redis = new swoole_redis;
$redis->connect('127.0.0.1', 6379, function ($redis, $result){
    if ($result === false) {
        // 连接失败处理
        return;
    }

    // 设置缓存
    $redis->set('key1', 'data1', function ($redis, $result){
        if ($result === false) {
            // 设置失败处理
            return;
        }

        // 获取缓存
        $redis->get('key1', function ($redis, $result){
            if ($result === false) {
                // 获取失败处理
                return;
            }

            echo $result; // 输出：data1
        });
    });
});

Using Workerman for data remote caching:

<?php
$memcached = new Memcached();
$memcached->addServer('localhost', 11211);

// 设置缓存
$memcached->set('key1', 'data1');

// 获取缓存
$result = $memcached->get('key1');
echo $result; // 输出：data1

Through the above In the sample code, we can see how to use Swoole's Redis client and Workerman's Memcached class to implement the function of remote data caching.

Summary:
This article introduces the optimization method of using Swoole and Workerman to local cache and remote cache of PHP and MySQL data, and gives specific code examples. Through the optimization of data caching, the performance and efficiency of applications can be greatly improved and the access pressure on the database can be reduced. I hope this article will be helpful to PHP developers in terms of performance optimization.
