php解压缩文件

1. 求php压缩解压rar和zip类源码

不用写,rar算法是有专利权的

RAR压缩算法是RARLab的专利,其它软件要使用或自己实现RAR算法的实作,都是要向RARLab申请许可或交钱的

zip算法php有自带的函数
====>
需求
PHP 4
The bundled PHP 4 version requires » ZZIPlib, by Guido Draheim, version 0.10.6 or later

PHP 5.2.0 or later
This extension uses the functions of » zlib by Jean-loup Gailly and Mark Adler.
=====>
所以用RAR只有通过命令行调用已经安装的rar程序实现打包,效果是一样的.具体调用方法参考各自软件说明.winrar也能用命令行调用,请看http://ke..com/view/2345.htm

2. 请高手指点：PHP 如何解压缩zip格式压缩的文件或压缩文件夹内的文件到指定目录

/**
* PHP在线压缩/解压实例
*/

date_default_timezone_set('prc');

$zip = new engine_compress_decompress();

if (isset($_POST))
{
$sourcePath = ''; //默认位置

if (isset($_FILES['upfile'])) //上传文件
{
$stmp = $zip->fileUpload('upfile');
$sourcePath = $stmp['sourcefile'];
$upfileError = $stmp['error'];
}
elseif (isset($_POST['inputfile'])) //输入目录或者文件
{
$sourcePath = $_POST['inputfile'];
}
elseif (isset($_POST['decompresssourcefiles'])) //解压缩提交
{
$isDecompress = $zip->decompress($_POST['decompresssourcefiles'], $_POST['topath']);
if (!empty($isDecompress['filelist']))
{
$href = '<script type="text/javascript" language="javascript">window.location.href=\'#decompress\'</script>';
}

}

$fileList = $zip->fileArray($sourcePath); //解压缩文件列表

if (isset($_POST['compressinputfileorfolder'])) //压缩文件目录或者文件输入
{
$sourcePath = $_POST['compressinputfileorfolder'];
$href = '<script type="text/javascript" language="javascript">window.location.href=\'#compress\'</script>';
$compressFilelist = $zip->compressFileArray($sourcePath); //压缩文件列表
}
elseif ((isset($_POST['selectcompressfilelist'])) && (isset($_POST['compresssavefilename'])))
{
$compressFiles = $zip->compress($_POST['selectcompressfilelist'], $_POST['compresssavefilename']); //真实检测
$isCompress = $zip->CompileZipFile($compressFiles, $zip->savePath, 'all');
if (!empty($isCompress))
{
$href = '<script type="text/javascript" language="javascript">window.location.href=\'#compress\'</script>';
}
}
}
