本文章提供一款完整的php目录 文件在线解压缩程序,他可打包指定目录并且把目录下所有目录与文件名都打包好,按rar的方式打包,目录结构不变,同时也提供解压功能.代码如下:
- $fz = new fmzip;
- $fz->setzipname("打包文件名");
- #打包/压缩
- $fz->setsource("待打包目录");
- $fz->compress($silent,$compress);
- #解包/解压
- $fz->settarget("待解包目录");
- $fz->uncompress($silent);
- */
- class fmzip
- {
- var $source; //压缩源
- var $target; //解压目的文件夹
- var $zipname;//压缩文件名
- var $handle; //打开压缩文件的句柄
- var $silent; //是否输出
- var $count_dir; //计数器_文件夹
- var $count_file;//计数器_文件
- var $dirlist;
- function setsource($source)//设置压缩源
- {
- if(!file_exists($source))
