下载提示那种。

<br /><?php<br />$file = 'test.zip';  <br />if(file_exists($file)){  <br />    header('content-type:application/octet-stream');  <br />    header('content-disposition:attachment; filename='.basename($file));  <br />    header('content-length:'.filesize($file));  <br />    readfile($file);  <br />}  <br />?><br />

$zipname = 'test.zip';<br />$filelist = array_slice(glob('images/*'), 0, 10);//待压缩文件列表<br />$zip = new ZipArchive;<br />$zip->open($zipname, ZIPARCHIVE::CREATE <br><font color='#FF8000'>------解决方案--------------------</font><br> ZIPARCHIVE::OVERWRITE);<br /> <br />foreach($filelist as $fn){<br />  $zip->addFile($fn);<br />}<br />$zip->close();

整合下这两个就可以了,经测试妥妥的。
然后就拿版主和二楼的结合写了个方法:
<br />function zipAndDownload($zipFileName,$zipDir){<br />        if(file_exists($zipFileName)){<br />            unlink($zipFileName);<br />            $zipFile = new ZipArchive();<br />            $fileList = array_slice(glob($zipDir) , 0 ); //待压缩文件列表<br />            $zipFile -> open($zipFileName , ZipArchive::CREATE <br><font color='#FF8000'>------解决方案--------------------</font><br> ZipArchive::OVERWRITE);<br />            foreach ($fileList as $files){<br />                $zipFile -> addFile($files);<br />            }<br />            $zipFile -> close();<br />            if(file_exists($zipFileName)){  <br />                header('content-type:application/octet-stream');  <br />                header('content-disposition:attachment; filename='.basename($zipFileName));  <br />                header('content-length:'.filesize($zipFileName));  <br />                readfile($zipFileName);  <br />            }  <br />        }<br />     }<br />
