代碼是這么寫的：

if($arr > 1){
    $content = json_decode($arr);
    $resarr = object_to_array($content);
    foreach ($resarr as $key=>$value){
        if(isset($resarr)){
            if($resarr == "上報開門記錄"){
                $socketopen = new Socketopenlog();
                $res = $socketopen->saves($resarr);
                echo $res;
                echo "已OK\n";
            }
//                    var_dump($resarr);
//                    die;
        }

    }
}else{
    echo "心跳包\n";
}
