tp5实现Redis的简单使用

<?php
namespace app\index\controller;

use think\Controller;
use think\session\driver\Redis;

class Index extends Controller
{
    public function index()
    {
        $redis = new Redis();
        if(is_null($redis->has(‘str‘))){
            var_dump($redis->set(‘str‘,‘this is redis_str‘));
        }else{
            var_dump($redis->get(‘str‘));
        }
    }
}
