0x00 代码如下

function addFileToZip($zip,$zipname,$path){

while(($filename = readdir($handler))!==false) {

if($filename != "." && $filename != ".." && $filename!= $zipname){

if (is_dir($path."/".$filename)) { //如果读取的某个对象是文件夹，则递归

addFileToZip($zip,$zipname,$path."/".$filename);

} else {

$zip->addFile($path."/".$filename);

}

}

}

@closedir($path);

}

function tar($zipname,$path) {

$zip = new ZipArchive(); //使用本类，linux需开启zlib，windows需取消php_zip.dll前的注释

if ($zip->open($zipname, ZipArchive::OVERWRITE) === TRUE) {

addFileToZip($zip,$zipname,$path);$zip->close();

} else {

exit('Unable to open file, or file creation failed!');

}

}

function download($zipname) {

if(!file_exists($zipname)){

exit("Zip file does not exist!");

}
