用PHP解压缩LZMA [英] Decompressing LZMA with PHP

问题描述

我有很多用LZMA压缩的SWF文件，我想以编程方式对服务器上的PHP进行解压缩和读取. 有人可以将我定向到PHP LZMA SDK吗?我已经为此进行了Google搜索，但到目前为止，除了指向损坏的链接的引用之外，什么都没有找到(针对php的7z扩展名?)

I have a load of SWF files compressed with LZMA that I would like to programatically decompress and read with PHP on my server. Can someone direct me to a PHP LZMA SDK? I've googled for it, but have so far found nothing but references to a broken link (7z extension for php?)

我有一个工作正常的python模块，该模块设法读取LZMA压缩SWF的标头，但它需要一个名为pyLZMA的模块，该模块似乎不想在我的服务器上安装，而让它在本地运行非常麻烦.屁股，所以我更喜欢一个PHP解决方案(如果存在).

I have a working python module that manages to read headers of LZMA compressed SWFs but it requires a module called pyLZMA which doesn't seem to want to install on my server, and getting it to work locally was a massive pain in the arse so I'd much prefer a PHP solution if one exists.

推荐答案

有一个名为 PHP-的库SevenZipArchive ，它是7za和7zr二进制文件的包装.在Linux中为我工作的简单测试方案:

There is a library called PHP-SevenZipArchive which is a wrapper to 7za and 7zr binaries. Simple test scenario working for me in linux:

安装p7zip软件包(yum install p7zip或类似版本)

install p7zip package (yum install p7zip or similar)

在linux shell中创建测试压缩文件

create test compressed file in linux shell

echo "Compressed data" | lzma -z > compressed.string

下载并解压缩PHP-SevenZipArchive

download and unzip PHP-SevenZipArchive

wget https://github.com/cmanley/PHP-SevenZipArchive/archive/master.zip
unzip master.zip

为解压缩的输出创建目录

create directory for decompressed output

mkdir out

创建测试php文件

<?php
require "./PHP-SevenZipArchive-master/SevenZipArchive.php";
$archive = new SevenZipArchive('compressed.string', array('binary'=>'/usr/bin/7za'));
$archive->extractTo('out');
?>

php -f ./index.php将创建输出文件/将其压缩

php -f ./index.php will create file out/compressed

cat out/compressed

压缩数据
