说明:
做WEB时用FTP上传零碎的文件会比较费时间,但上传打包后的单个文件会很快,在上传之后可以使用此程序将zip文件解压。代码参考了纯粹空间的“faisun_unzip -在线解压ZIP文件程序 V1.0”,略有修改。
用法:
第一步:制作zip.php文件。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | <?php include ( 'zip.class.php' ); if ( empty ( $_GET [ 'f' ])){ echo 'Usage: ?f=file.zip&d=directory' ; } else { $file = $_GET [ 'f' ]; $directory = $_GET [ 'd' ]; // zip.class.php会处理这块数据 if (preg_match( '/\.zip$/mis' , $file )){ $z = new zip(); $result = $z ->extract( $file , $directory ); if ( $result ==-1){ echo "<br>File: [$file] error." ; } echo "<br>Done. Folders: $z->totalFolders , Files: $z->totalFiles ." ; } else { echo "<br>Wrong file format." ; } } ?> |
第二步:上传后解压。
1 2 | http: //domain/zip.php?f=archive.zip&d=web #参数“f”是上传的包,“d”是解压到的目录(同级目录)。 |
