压缩-php获取rar文件里面的内容，输出来如何解析？

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(&#39;222.rar&#39;) or die(&quot;Failed to open Rar archive&quot;);
$entries_list = rar_list($rar_file);
header(&#39;Content-Type: text/plain&#39;);
print_r($entries_list);

得到数据如下：

Array
(
    [0] =&gt; RarEntry Object
        (
            [rarfile:RarEntry:private] =&gt; RarArchive Object
                (
                )
