在多卷存档中扫描.rar文件内容条目(Scanning .rar file content entries on multi volume archive)

 我正在玩php rar 
 
 http://www.php.net/manual/en/intro.rar.php 
 
 目标：从第一卷收集多卷rar档案的文件（名称）信息。 
 
 示例： 
 
 完整卷： testArchive.rar ， testArchive.r00 
 
 可用： testArchive.rar 
 
 从testArchive.rar中扫描归档文件中的文件， 不带 testArchive.r00 
 
 Winrar（rarlabs.com）为您提供第一卷中多卷rar归档的归档（文件）内容。 
 现在我想通过php完成这个任务。 
 
 我尝试了以下，但这给了我一个空的数组。 
 
function retnull() { return null; }

$arch = RarArchive::open("testArchive.rar" , NULL , 'retnull' );
$arch->setAllowBroken(true);

if ($arch === FALSE)
    die("Cannot open testArchive.rar");

$entries = $arch->getEntries();
if ($entries === FALSE)
    die("Cannot retrieve entries");

echo '<pre>';
    print_r($entries);
echo '</pre>';
 
 我不需要提取rar文件，但只需要像winrar程序那样在存档内的文件夹/文件的内容[NAMES]。 
 
 有人能给我一个正确的方向提示吗？ 

I am playing around with php rar 
 
http://www.php.net/manual/en/intro.rar.php
 
Goal : Gather file (name) information of multi volume rar archives, from only the first volume.
 
Example : 
 
Complete volume : testArchive.rar , testArchive.r00 
 
Available : testArchive.rar
 
Scan files inside archive from testArchive.rar WITHOUT testArchive.r00
 
Winrar ( rarlabs.com ) gives you the archived (file) content of the multi volume rar archive from the first volume.
 Now I want this accomplished by php.
 
I tried the following but this gives me an empty array.
 
function retnull() { return null; }

$arch = RarArchive::open("testArchive.rar" , NULL , 'retnull' );
$arch->setAllowBroken(true);

if ($arch === FALSE)
    die("Cannot open testArchive.rar");

$entries = $arch->getEntries();
if ($entries === FALSE)
    die("Cannot retrieve entries");

echo '<pre>';
    print_r($entries);
echo '</pre>';
 
I do not need to extract the rar files , but only need the content [NAMES] of the folders/files inside the archive like the program winrar does.
 
Can somebody give me a hint in the right direction ?
