How to cache thinkphp interface

Thinking Doorframe PHP framework has become one of the preferred frameworks for many developers. It is not only efficient and easy to use, but also supports various cache drivers, including file caching, Memcached, Redis, etc. In this article, we will discuss how to use caching in ThinkPHP applications to improve efficiency.

1. ThinkPHP cache introduction

The ThinkPHP framework provides a unified cache operation interface, and developers can use various cache drivers to manage and control data caching. Cache can store any type of data, such as strings, arrays, objects, etc. Because caching stores data in memory, it can significantly reduce the load on the database and improve application responsiveness.

2. File cache

File cache is a cache driver provided by the ThinkPHP framework by default. It stores cache data in the local file system, and these files can be automatically deleted after the cache expires. To use file cache, you need to configure the cache settings in the application configuration file:

'cache' => [
    // 默认驱动器为文件缓存
    'default' => 'file',
    // 文件缓存设置
    'stores' => [
        'file' => [
            'type' => 'File',
            'path' => APP_PATH . 'runtime/cache/',
        ],
    ],
],

In this configuration, we set the default cache drive to file cache and set the storage path of cache data to ./runtime /cache/ directory.

To use caching in an application, we can use the Cache class:

use thinkacadeCache;

// 设置缓存
Cache::set('key', 'value', 3600);

// 获取缓存
$value = Cache::get('key');

// 删除缓存
Cache::delete('key');

3. Memcached Cache

Memcached is a high-performance, distributed In-memory object caching system, widely used in web applications. In ThinkPHP framework, we can easily use Memcached cache driver to manage cache data. To use Memcached caching, make sure the Memcached service is installed and started.

'cache' => [
    // 默认驱动器为Memcached缓存
    'default' => 'memcached',
    // Memcached缓存设置
    'stores' => [
        'memcached' => [
            'type'   => 'Memcached',
            'host'   => '127.0.0.1',
            'port'   => 11211,
            'expire' => 3600,
            'prefix' => '',
        ],
    ],
],

In this configuration, we set the default cache drive to Memcached and set the cached data expiration time to 3600 seconds.

If you want to use caching in your application, we can use the Cache class:

use thinkacadeCache;

// 设置缓存
Cache::store('memcached')->set('key', 'value', 3600);

// 获取缓存
$value = Cache::store('memcached')->get('key');

// 删除缓存
Cache::store('memcached')->delete('key');

4. Redis cache

Redis is widely used for caching and messaging Open source in-memory data structure storage for queues. In the ThinkPHP framework, we can use the Redis cache driver to manage and control cached data.

'cache' => [
    // 默认驱动器为Redis缓存
    'default' => 'redis',
    // Redis缓存设置
    'stores' => [
        'redis' => [
            'type' => 'redis',
            'host' => '127.0.0.1',
            'port' => 6379,
            'password' => '',
            'select' => 0,
            'timeout' => 0,
            'expire' => 3600,
            'persistent' => false,
            'prefix' => '',
        ],
    ],
],

In this configuration, we set the default cache drive to Redis and specified the location and port number of the Redis server.

To use Redis caching in an application, we can use the Cache class:

use thinkacadeCache;

// 设置缓存
Cache::store('redis')->set('key', 'value', 3600);

// 获取缓存
$value = Cache::store('redis')->get('key');

// 删除缓存
Cache::store('redis')->delete('key');

5. Cache tag

The cache tag is a type of cached data The method of appending tags allows us to distinguish and classify different cached data. In the ThinkPHP framework, we can use cache tags to manage and control different cache data.

use thinkacadeCache;

// 设置缓存，同时添加缓存标记
Cache::store('file')->tag('tag1')->set('key1', 'value1', 3600);

// 根据标记获取缓存
$data = Cache::store('file')->tag('tag1')->get('key1');

// 根据标记删除缓存
Cache::store('file')->tag('tag1')->clear();

In this example, we used a file cache drive and classified the cached data using tag tag1. We can use the tag() method of the Cache class to tag the cache.

6. Summary

In this article, we discussed how to use caching in ThinkPHP applications to speed up response times. We've introduced several common cache drivers, including file cache, Memcached, and Redis. We also mentioned the importance of using cache tags to classify and manage cached data. By using caching, we can improve application performance and responsiveness while reducing database load.
