faisun_unzip - 在線解压ZIP文件程序 V1.0 转下请注明：本程由 纯粹空间(http://www.softpure.com) 提供、作者：faisun( faisun@sina.com). 使用方法:zip 文件を FTP 経由で本文同然の目录下、选择 zip 文件; または直接点击“浏览... 解決された結果、元のコンテンツが保持されます。
选择ZIP文件:	- 请选择 - $fdir = opendir('./'); while($file=readdir($fdir)){ if(!is_file($file)) continue; if(preg_match('/.zip$/mis',$file)){ echo "<オプション値='$file'>$filern"; } } ?> < /select>
解压到目录:	(留空は本目录, 必须有書入权限)
验证密码:	(ソース文件中設定的秘密)
