RAR从字母顺序中提取出PHP

Question

$temFile = $_FILES["file"]["tmp_name"];
if($rar = RarArchive::open($tempFile)){

    $files = $rar->getEntries();
}

RarArchive :: open按字母顺序列出文件。

通过操作系统查看普通文件，RAR中的文件列表中有过滤器。但它们都不会以任何方式击败PHP返回的顺序 - ＆gt; getEntries（）。那么班级过滤的位置标准是什么？ （我特别需要这些信息）我所谈论的位置是由＆gt;返回的每个文件的每个位置属性。 getEntries（），它从0开始按升序排列到RAR中的总条目。

返回示例（查看文件名）：
