提问by Kichu
I want to unzip directorires.
我想解压缩目录。
That means i have a zipped directory name with xxx.zip.In manuall i right clicked on the zipped directory and do extract folder,then i got an unzipped dirtectory with name xxxand also in this directory have a same directory xxx.In the subfolder will contained the files.
这意味着我有一个压缩目录名称xxx.zip。在手册中，我右键单击压缩目录并提取文件夹，然后我得到了一个带有名称的解压缩目录，xxx并且在这个目录中也有一个相同的目录xxx。在子文件夹中将包含这些文件。
That means, xxx->xxx->files this is the heirarchi of unzipped folder.
这意味着，xxx->xxx->files 这是解压文件夹的层次结构。
So in my site i want to unzipp a directory using php code.
所以在我的网站中，我想使用 php 代码解压缩一个目录。
How can i do this? I need only xxx->filesnot xxx->xxx->filesstructure.
我怎样才能做到这一点？我只需要xxx->files不是xxx->xxx->files结构。
How can i do this?
我怎样才能做到这一点？

<?php
$zip = zip_open("zip.zip");
if ($zip) {
while ($zip_entry = zip_read($zip)) {
$fp = fopen("zip/".zip_entry_name($zip_entry), "w");
if (zip_entry_open($zip, $zip_entry, "r")) {
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
fwrite($fp,"$buf");
zip_entry_close($zip_entry);
fclose($fp);
}
}
zip_close($zip);
}
?>

See this http://www.php.net/manual/en/ziparchive.extractto.php
看到这个http://www.php.net/manual/en/ziparchive.extractto.php
$zip = new ZipArchive;
if ($zip->open('E:\pathto\zip\ashok_subedi.zip') === TRUE) {
$zip->extractTo('E:\pathto\extrac\myzip');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}

You can upload this file to your web-server and run it. It will ask you to choose a zip file for unzipping, and you could specify the path where you want to unzip. In case you want to unzip the file in the current location, just leave the unzip path blank. On finishing the unzipping, it will give you feedback, too.
您可以将此文件上传到您的网络服务器并运行它。它会要求您选择一个 zip 文件进行解压缩，您可以指定要解压缩的路径。如果您想在当前位置解压缩文件，只需将解压缩路径留空。解压完成后，它也会给你反馈。
