tp5.1下redis配置和使用

//1.config目录下新建redis.php
<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2019/12/18
 * Time: 13:14
 */

return [
    'host' => '127.0.0.1',
    'port' => '6379'
];


//2.extend目录下新建->module文件夹->Redis.php文件
<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2019/12/18
 * Time: 13:16
 */

namespace Module;

class Redis extends \Redis
{
    public static function redis() {
        $con = new \Redis();
        $con->connect(config('redis.host'), config('redis.port'), 5); //连接redis 超过5秒放弃
        $con->auth('123456'); //密码验证  没有可不写
        $con->select(0); //选择数据库
        return $con;
    }
}


//3.设置助手函数 thinkphp文件下->helper.php文件
if (!function_exists('redis')) {
    /**
     * 获取容器对象实例
     * @return Container
     */
    function redis()
    {
        return \module\Redis::redis();
    }
}


//4.控制器中使用
redis()->set('test','111');
$data = redis()->get('test'); //111
