我想解压导演。
这意味着我有一个带有xxx.zip的压缩目录名。在manuall我右键单击压缩目录并执行提取文件夹，然后我得到一个名为xxx的解压缩的物品，也在此目录中具有相同的目录xxx。在子文件夹中将包含文件。
这意味着，xxx-＆gt; xxx-＆gt;文件这是解压缩文件夹的heirarchi。
因此，在我的网站中，我想使用php代码解压缩目录。
我该怎么做？我只需要xxx->files而不是xxx->xxx->files结构。
我该怎么做？

<?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);
}
?>

请参阅此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';
}

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，并且可以指定要解压缩的路径。如果要在当前位置解压缩文件，只需将解压缩路径留空即可。完成解压缩后，它也会给你反馈。
