压缩扩展php数组对象

最近有一个需求:将rar压缩文件里面的文件名、大小获取出来,解析成json输出来;
查阅了无数资料,得知添加php_rar.dll(如果是zip的话,就添加php_zip.dll扩展),最后通过程序得到rar的相关内容,但对里面获取到的内容格式不知道怎么解析成json,求大神指点一二。

$rar_file = rar_open('222.rar') or die("Failed to open Rar archive");
$entries_list = rar_list($rar_file);
header('Content-Type: text/plain');
print_r($entries_list);

得到数据如下:

Array
(
    [0] => RarEntry Object
        (
            [rarfile:RarEntry:private] => RarArchive Object
                (
                )
