Analysis of Cache Query Operation in ThinkPHP5 Framework

This article illustrates the cache query operation of ThinkPHP5 framework. Share it for your reference, as follows:

Cache setup and use:

1. Set the following in\ application\ config.php:

'cache' => [
  //  Using compound cache types 
  'type' => 'complex',
  //  Cache used by default 
  'default'  => [
    //  Driving mode 
    'type'  => 'File',   // ! ! Set the cache mode of substitution here 
    //  Cache save directory 
    'path'  => CACHE_PATH,
  ],
  //  File cache 
  'file'  => [
    //  Driving mode 
    'type'  => 'file',
    //  Set different cache storage directories 
    'path'  => RUNTIME_PATH . 'file/',
  ],
  // redis Cache 
  'redis'  => [
    //  Driving mode 
    'type'  => 'redis',
    //  Server address 
    'host'    => '127.0.0.1',
  ],
],

2. In the controller

use \think\Cache;

3. Used in the controller

Cache::set('name', 'tom',3600);
Cache::get('name');

Cache query:

1. Simple cache query:

In any controller (if you want to complete data query in model, you need to use Db class)

public function cacheSelect()
{
  $_data = db(' Table name ')->cache(60)->find();
  dump($_data);
  //60s Extract data from the internal cache without querying from the database 
}

2. Set the specified cache identity to make the query more efficient and convenient to use:

public function cacheSelect()
{
  $result = db(' Table name ')->cache(' Random character ')->where('id','<', 10)->select();
}
//cacheKey The method is any method of any controller 
public function cacheKey(){
  // Call the found data directly elsewhere to avoid querying again: 
  $data = \think\Cache::get(' Random character ');
  dump($data);
}
