如何仅使用 PHP 提取具有密码的 ZIP 文件? [英] How to extract a ZIP file that has a password using only PHP?

问题描述

我在这里只看到一个问题，但它没有回答我的问题.我正在运行一个典型的 LAMP 服务器，该服务器具有最新的 PHP 5 和 MYSQL 5 以及 Redhat Linux.

I have seen only one question on here but it does not answer my question. I am running a typical LAMP server that has the most up to date PHP 5 and MYSQL 5 with Redhat Linux.

我需要找到一个仅限 PHP 的解决方案，因为我的主机不允许我使用 shell.

I need to find a PHP only solution because my host does not allow me to use shell.

这是我的代码，用于从 vBulletin 上传中提取未加密的 ZIP 到另一个目录:

Here is my code that extracts ZIPs that are not passworded from vBulletin uploads to another directory:

if ($_GET['add'] == TRUE){
$zip = new ZipArchive;
 $res = $zip->open($SOURCE FOLDER);
 if ($res === TRUE) {
     $zip->extractTo('$DESTINATION FOLDER/');
     $zip->close();
     echo 'File has been added to the library successfuly';
     //Add a flag to that file to indicate it has already been added to the library.
     mysql_query("UPDATE attachment SET library = 1 WHERE filedataid='$fileid'");    
 } else {
     echo 'A uncompression or file error has occured';
 }}

肯定有某种方法可以只使用 PHP 来做到这一点！谢谢.

There must be some way to do this using just PHP, surely! Thank you.

更新:我的主机通知我服务器上安装了 gzip，但没有安装 7-Zip.我也在研究 shell 访问.

UPDATE: My host informs me that gzip is installed on the server but not 7-Zip. I am looking into shell access too.

推荐答案

为脚本提供 7zip 可执行文件并调用它以通过 system() 使用密码解压缩文件.

Have 7zip executable available to the script and call it to uncompress the file with the password via system().

$strCommandLine = "7z e fileToUnzip.7z -pTHEPASSWORD";
system($strCommandLine);

如果您的主机安装了 unzip，您可以执行类似的操作.请参阅 http://linux.about.com/od/commands/l/blcmdl1_unzip.htm.

You can do something similar with unzip, if your host has that installed. See http://linux.about.com/od/commands/l/blcmdl1_unzip.htm.

它支持带密码的-P，所以是这样的:

It supports -P with a password, so something like this:

$strCommandLine = "unzip fileToUnzip.7z -P THEPASSWORD";
system($strCommandLine);

警告:如果有人在系统上执行 ps 并看到您的 unzip 命令正在运行，他们可能会在该命令行上看到您的密码.

Caveat: someone could see your password on that command line if they do a ps on the system and see your unzip command running.
