下载提示那种。

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

我的图片怎样打包成如test.zip文件呢,求指导

$zipname = 'test.zip';$filelist = array_slice(glob('images/*'), 0, 10);//待压缩文件列表$zip = new ZipArchive;$zip->open($zipname, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE); foreach($filelist as $fn){  $zip->addFile($fn);}$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:
function zipAndDownload($zipFileName,$zipDir){        if(file_exists($zipFileName)){            unlink($zipFileName);            $zipFile = new ZipArchive();            $fileList = array_slice(glob($zipDir) , 0 ); //待压缩文件列表            $zipFile -> open($zipFileName , ZipArchive::CREATE | ZipArchive::OVERWRITE);            foreach ($fileList as $files){                $zipFile -> addFile($files);            }            $zipFile -> close();            if(file_exists($zipFileName)){                  header('content-type:application/octet-stream');                  header('content-disposition:attachment; filename='.basename($zipFileName));                  header('content-length:'.filesize($zipFileName));                  readfile($zipFileName);              }          }     }
Copy after login

如??已解?,???。
