ThinkPHP 中使用Redis

环境.env

[app]
app_debug = "1"
app_trace = ""

[database]
database = ""
hostname = "127.0.0.1"
hostport = ""
password = ""
prefix = "ls_"
username = ""

[redis] 
hostname = "127.0.0.1"
hostport = "6379" 
password = "123456"
prefix = "redis_" 

[project]
env_name = ""
file_domain = "xxx.xxx.xxx.xxx" 

配置 config

<?php 

// +----------------------------------------------------------------------
// | 缓存设置
// +----------------------------------------------------------------------
use think\facade\Env; 

return [
    // 缓存配置为复合类型
    'type'  =>  'complex', 
    'default'	=>	[
      'type'	=>	Env::get('cache.type','File'),
      // 全局缓存有效期（0为永久有效）
      'expire'=>  0, 
      // 缓存前缀
      'prefix'=>  'shop_',
       // 缓存目录
      'path'  =>  '',
    ],
    'redis'	=>	[
      'type'	=>	'redis',
      'host'	=> Env::get('redis.hostname'),
      'port'    => Env::get('redis.hostport'),
      'password' => Env::get('redis.password'),
      'expire'=>  0, 
      'prefix'=>  'redis_', // 缓存前缀
    ],    
    // 添加更多的缓存类型设置
];

Redis缓存处理类

控制器中使用

<?php 


namespace app\data\controller; 
 
use app\common\logic\RedisLogic;   

class Test extends Base 
{ 
    public function redis()
    { 
		if(class_exists('Redis')){ 
		    echo '<br>服务器支持Redis服务<br>';  
		    $redis = new RedisLogic();     
		    $redis->setCache('key',12365478); 
		    echo '<br>key:',$redis->getCache('key'); 
		    echo $redis->delete('key');   
		}
		else{
		    echo '服务器不支持Redis服务';
		}
    }
    
}
