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';}}}
