PHP使用 Redis批量删除过期数据

public function handle()
{
$this->redis = new Redis();
$this->redis->connect(env(“REDIS_HOST”), env(“REDIS_PORT”));
$this->redis->auth(env(“REDIS_PASSWORD”));

    $pre = "api_user_auth_";
1

// $pre{=}^{\prime }test{:}^{\prime };//for($i = 0; $i < 100; $i++) {
// $this->redis->set($pre . “$i","$i”);
// }

    //返回的结果集为空的话，函数不返回，而是直接继续执行scan命令
    $this->redis->setOption(Redis::OPT_SCAN, Redis::SCAN_RETRY);
    $it = NULL;
    static $count = 0;
    while ($arr_keys = $this->redis->scan($it, "$pre*", 1000)) {
        $get_key_ttl = [];
        foreach ($arr_keys as $key=>$item) {
           $get_key = $this->redis->ttl($item);
           if ($get_key == -1){
               $get_key_ttl[$key] = $item;
           }
        }
        call_user_func_array([$this->redis, 'del'], $get_key_ttl);
        $count += count($get_key_ttl);
        //echo var_export($get_key_ttl, true) . PHP_EOL;
        //call_user_func_array([$this->redis, 'del'], $arr_keys);
        //echo var_export($arr_keys, true) . PHP_EOL;
    }
    Log::info('delete redis user---'.$count);
    return true;
