With the continuous development of Internet technology, caching is becoming more and more important for optimizing the performance of websites or applications. In the ThinkPHP6 framework, we can use Memcached for caching operations to improve the response speed of the application. This article will introduce how to use Memcached for caching operations in the ThinkPHP6 framework.

1. What is Memcached?

Memcached is a high-performance distributed memory object caching system for accelerating dynamic web applications. It improves the performance of web applications by reducing frequent database accesses by storing bookmarks in RAM. It can also be used to cache other normal content such as HTML pages and API responses.

2. How to install Memcached?

First of all, Memcached needs to be installed on the server to use it. Under Linux, you can use apt-get, yum and other commands to install.

The specific method is as follows:

1. Install tools

sudo apt-get install build-essential

sudo apt-get install libevent-dev

2. Download Memcached

wget http://www.memcached.org/files/memcached-1.5.20.tar.gz

3. Unzip and enter the folder

tar -zxvf memcached-1.5.20.tar.gz

cd memcached-1.5.20

4. Compile and install

./configure

make && make install

5. Install PHP’s Memcached extension

sudo apt-get install php-memcached

3. How to use Memcached in ThinkPHP6 Perform caching operations?

1. Configure in config/cache.php

In the config/cache.php file, we need to set the cache driver to memcached and configure memcached related information.

The configuration is as follows:

<?php

return [
    // 默认缓存驱动
    'default' => env('cache.driver', 'memcached'),
    // 缓存连接方式配置
    'stores'  => [
        'file' => [
            'driver' => 'file',
            'path'   => runtime_path('cache'),
        ],
        'redis' => [
            'driver' => 'redis',
            'host'   => env('cache.redis.host', '127.0.0.1'),
            'port'   => env('cache.redis.port', 6379),
            'password' => env('cache.redis.password', ''),
            'select' => env('cache.redis.select', 0),
            'timeout' => env('cache.timeout', 0),
            'expire' => env('cache.expire', 0),
            'persistent' => false,
            'prefix' => '',
        ],
        'memcached' => [
            'driver'    => 'memcached',
            'host'      => env('cache.memcached.host', '127.0.0.1'),
            'port'      => env('cache.memcached.port', 11211),
            'username'  => env('cache.memcached.username', ''),
            'password'  => env('cache.memcached.password', ''),
        ],
    ],
];

In the above configuration, you need to pay attention to the following:

(1) The cache driver defaults to memcached:

The default will be here The cache driver is set to memcached, which means that all cache operations will use this driver.

(2) Add the memcached option to the stores array:

Add the memcached option to the stores array, and set relevant parameters for connecting to memcached.

2. Using cache

In the ThinkPHP6 framework, you can use the cache class to perform cache operations. Among them, the cache class provides methods such as get, set, has, delete, etc. to manage the cache.

Use the following code:

<?php 

namespace appindexcontroller; 

use thinkacadeCache; 

class Index { 

    public function index() { 
        //写入缓存 
        Cache::set('name', 'ThinkPHP6'); 

        //获取缓存 
        $name = Cache::get('name'); 

        //判断缓存 
        if ( Cache::has('name') ) { 
            //删除成功 
            Cache::delete('name'); 
        } 

        //清空缓存 
        Cache::clear(); 
    } 
}

4. Conclusion

Through the above four steps, you can use Memcached for caching operations in ThinkPHP6. Through caching technology, the response speed of the application can be greatly improved and the user access experience can be improved.
