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';
		}
    }
    
}
