The practice of integrated caching technology in ThinkPHP6

With the continuous development of network technology, caching technology has become an indispensable technology in modern website and application development. As one of the most popular PHP development frameworks in China, ThinkPHP has integrated a variety of caching technologies in its latest version, ThinkPHP6. This article will introduce the practice of ThinkPHP6 integrated caching technology, allowing readers to better master this technology.

1. Overview of Caching Technology of ThinkPHP6

The caching technology integrated by ThinkPHP6 mainly includes file cache, Redis cache, Memcached cache and database cache. These caching technologies can be set through configuration files, making it easy for developers to adjust to suit different application needs.

1. File caching

File caching is a way to generate a cache file on the server and load data from the database into the cache. This caching technology operates slower, but is still a good choice in some small applications. ThinkPHP6 supports file caching methods including File and Lite.

2. Redis cache

Redis is a fast open source cache database that can support many different types of data structures, including strings, hash tables, lists, etc. . Redis caching technology can be applied to web applications that have very demanding performance requirements. In ThinkPHP6, Redis caching can be easily used through configuration files.

3. Memcached cache

Memcached is a fast and efficient distributed cache system, mainly used to reduce the number of database accesses and improve application performance. In ThinkPHP6, Memcached caching can also be set through the configuration file.

4. Database cache

Database cache is a caching technology that stores data in a database. Because the data is stored on disk, this method of caching is slower, but can support more data and a greater number of concurrent accesses than file caching. ThinkPHP6 supports multiple database caching methods, including Mysql, Sqlite, Pgsql, Oracle, etc.

2. Practice of ThinkPHP6 integrated Redis caching technology

Redis, as a commonly used memory caching technology, has been widely used in Web application development. While using Redis cache, you can also optimize the management of cache Key and Value by setting the maximum cache time.

The following are the steps to implement Redis caching using the ThinkPHP6 framework as an example:

1. Install Redis extension

First you need to ensure that Redis has been installed on the server Extension. You can perform the installation in the terminal through the following code:

pecl install redis

After the installation is completed, you need to add the Redis extended configuration item in the php.ini file:

extension=redis.so

2. Modify the configuration file

Modify the config/cache.php file in the ThinkPHP6 framework and set the default caching method to Redis:

'type' => 'redis',

At the same time, make some related Redis cache settings, such as cache prefix and maximum cache Time, etc.:

'prefix' => 'think_',
'expire' => 3600,
'select' => 0,
'timeout' => 0,
'persistent' => false,
'password' => '',

3. Using Redis cache

When using Redis cache in an application, you need to use the relevant methods provided by the Cache class. For example:

// 写入缓存
Cache::set('name', 'thinkphp', 3600);
// 读取缓存
Cache::get('name');
// 删除缓存
Cache::rm('name');

The above three methods are used to write cache, read cache and delete cache respectively. When using it, you need to pay attention to the cache Key settings. It is recommended to use a form like "prefix_key" to avoid conflicts with other applications.

3. Summary

This article introduces the various caching technologies integrated in the ThinkPHP6 framework, especially taking actual cases as examples to elaborate on how to use Redis caching technology. In practice, developers should choose the most suitable caching technology based on application scenarios and regularly maintain caches to ensure the efficient operation of web applications.
