thinkphp6 cache time setting

ThinkPHP6 is an efficient, simple and flexible PHP background development framework. During the development process, in order to improve website performance and user experience, we often need to use caching technology. However, once the cache validity period expires, it will affect the performance of the website. Therefore, setting the cache time is very important.

ThinkPHP6 framework provides a variety of cache drivers, including file cache, Redis cache, Memcached cache, etc. This article will mainly introduce how to set the cache time of file cache and Redis cache.

1. Cache time setting of file cache

In the configuration file (config/cache.php), you can set the default cache time for different cache drivers.

return [

    // 默认缓存驱动
    'default' => env('cache.driver', 'file'),

    // 缓存连接配置（根据缓存驱动选择配置）
    'stores'  => [
        'file' => [
            'driver' => 'file',
            'cache_subdir' => true,
            'prefix' => '',
            'path' => env('runtime_path') . 'cache',
            'expire' => 3600, // 默认缓存时间1小时
        ],
        // ...
    ],
];

In the above code, the 'expire' option sets the default cache time of the file cache to 1 hour. If you need to set a different cache time, you can set it when using the cache, for example:

// 设置缓存有效期为10分钟
Cache::store('file')->set('key', 'value', 600);

In the above code, the third parameter of the set() method sets the cache time to 600 seconds, which is 10 minutes. .

2. Redis cache cache time setting

The Redis cache cache time can be set in the configuration file (config/cache.php), for example:

return [

    // 默认缓存驱动
    'default' => env('cache.driver', 'redis'),

    // 缓存连接配置（根据缓存驱动选择配置）
    'stores'  => [
        'redis' => [
            'driver' => 'redis',
            'connection' => 'cache',
            'prefix' => '',
            'expire' => 3600, // 默认缓存时间1小时
        ],
        // ...
    ],
];

Above In the code, the 'expire' option sets the default cache time of the Redis cache to 1 hour. In actual use, the cache time can be set through the following code:

// 设置缓存有效期为10分钟
Cache::store('redis')->set('key', 'value', 600);

In the above code, the third parameter of the set() method sets the cache time to 600 seconds, which is 10 minutes.

3. Cache driver custom cache time

In addition to setting the default cache time in the configuration file, we can also customize the cache time when using the cache. For example, when using file caching:

// 设置缓存有效期为10分钟
Cache::store('file')->put('key', 'value', now()->addMinutes(10));

In the above code, the third parameter of the put() method sets the cache time to 10 minutes.

Summary

In the caching operation of the ThinkPHP6 framework, setting the cache time is very important. The default cache time can be set in the configuration file, or the cache time can be customized when using caching. Reasonably setting the cache time can improve website performance and user experience to a certain extent.
