ThinkPHP6 file caching operation: improving data reading speed

In Web development, data reading speed is a very important factor. To increase data reading speed, caching is a common solution. ThinkPHP6 provides a rich caching mechanism, of which file caching is a simple and effective way. This article will introduce how to use ThinkPHP6's file cache to improve data reading speed.

1. Configuration file caching

In ThinkPHP6, we can use file caching to cache configuration files. By caching the configuration file, you can avoid file reading every time the configuration file is accessed, thereby improving efficiency.

First, create a new cache.php configuration file in the config directory and configure the file cache-related information, for example:

 true, // 缓存文件路径 'path' => app()->getRuntimePath() . 'config/', // 缓存文件后缀 'suffix' => '.php', ];

Next, add it to the app.php configuration file in the config directory The following code:

 [ 'type' => 'File', 'path' => '', 'suffix' => '', ], ];

After the above steps are completed, the configuration file cache will take effect.

2. Data Cache

In addition to configuration file caching, ThinkPHP6 also provides file caching to store arbitrary data, such as database query results, data returned by API, etc. By caching this data, the database load can be reduced and the data reading speed can be increased.

1. Cache data

In the controller, we can use the cache class Cache to cache data. For example, cache database query results:

where('id', 1)->find(); // 将查询结果进行缓存 Cache::set('user_info', $data, 3600); return '数据缓存成功'; } }

In the above code, we use the Cache::set() method to cache the database query results $data, and the cache validity time is 3600 seconds.

2. Read cached data

When cached data needs to be used elsewhere, we can use the Cache::get() method to read cached data, for example:

        

         Copy after login
        
       

Through the Cache::get() method, we can quickly obtain data from the cache without performing database query operations.

3. Cache update

When the data changes, we need to update the cache in time to ensure the accuracy of the cached data. In ThinkPHP6, we can use the Cache::delete() method to delete cached data. For example, when a user modifies personal information, we can update the cached user information, as shown below:

        

         Copy after login
        
       

In the above code, we use the Cache::delete() method to correspond to the 'user_info' key The cached data is deleted. When the cached data is accessed next time, the system will re-obtain the latest data from the database for caching.

Through the above steps, we can use the file caching mechanism of ThinkPHP6 to quickly increase the data reading speed. By caching configuration files and data, you can reduce file reading and database query operations, improve system efficiency, and give users a better experience when visiting the website.
