這篇文章主要介紹了關于php打包zip圖片下載的方法，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下1.引入類包 zipfile

html' target='_blank'>class zipfile { var $datasec = array (); var $ctrl_dir = array (); var $eof_ctrl_dir = /x50/x4b/x05/x06/x00/x00/x00/x00  var $old_offset = 0; function unix2_dostime($unixtime = 0){ $timearray = ($unixtime == 0) ? getdate () : getdate($unixtime);  if ($timearray [ year ] 1980){ $timearray [ year ] = 1980; $timearray [ mon ] = 1; $timearray [ mday ] = 1; $timearray [ hours ] = 0; $timearray [ minutes ] = 0; $timearray [ seconds ] = 0; return (($timearray [ year ] - 1980) 25) | ($timearray [ mon ] 21) | ($timearray [ mday ] 16) | ($timearray [ hours ] 11) | ($timearray [ minutes ] 5) | ($timearray [ seconds ] 1); function add_file($data, $name, $time = 0){ $name = str_replace( // , / , $name); $dtime = dechex($this- unix2_dostime($time)); $hexdtime = /x . $dtime [6] . $dtime [7] . /x . $dtime [4] . $dtime [5] . /x . $dtime [2] . $dtime [3] . /x . $dtime [0] . $dtime [1]; eval( $hexdtime = . $hexdtime .  $fr = /x50/x4b/x03/x04  $fr .= /x14/x00  $fr .= /x00/x00  $fr .= /x08/x00  $fr .= $hexdtime; $unc_len = strlen($data); $crc = crc32($data); $zdata = gzcompress($data); $zdata = substr(substr($zdata, 0, strlen($zdata)- 4), 2); $c_len = strlen($zdata); $fr .= pack( V , $crc); $fr .= pack( V , $c_len); $fr .= pack( V , $unc_len); $fr .= pack( v , strlen($name)); $fr .= pack( v , 0); $fr .= $name; $fr .= $zdata; $fr .= pack( V , $crc); $fr .= pack( V , $c_len); $fr .= pack( V , $unc_len); $this- datasec [] = $fr; $cdrec = /x50/x4b/x01/x02  $cdrec .= /x00/x00  $cdrec .= /x14/x00  $cdrec .= /x00/x00  $cdrec .= /x08/x00  $cdrec .= $hexdtime; $cdrec .= pack( V , $crc); $cdrec .= pack( V , $c_len); $cdrec .= pack( V , $unc_len); $cdrec .= pack( v , strlen($name)); $cdrec .= pack( v , 0); $cdrec .= pack( v , 0); $cdrec .= pack( v , 0); $cdrec .= pack( v , 0); $cdrec .= pack( V , 32); $cdrec .= pack( V , $this- old_offset); $this- old_offset += strlen($fr); $cdrec .= $name; $this- ctrl_dir[] = $cdrec; function add_path($path, $l = 0){ $d = @opendir($path); $l = $l 0 ? $l : strlen($path) + 1; while($v = @readdir($d)){ if($v == . || $v == .. ){ continue; $v = $path . / . $v; if(is_dir($v)){ $this- add_path($v, $l); } else { $this- add_file(file_get_contents($v), substr($v, $l)); function file(){ $data = implode( , $this- datasec); $ctrldir = implode( , $this- ctrl_dir); return $data . $ctrldir . $this- eof_ctrl_dir . pack( v , sizeof($this- ctrl_dir)) . pack( v , sizeof($this- ctrl_dir)) . pack( V , strlen($ctrldir)) . pack( V , strlen($data)) . /x00/x00  function add_files($files){ foreach($files as $file){ if (is_file($file)){ $data = implode( , file($file)); $this- add_file($data, $file); function output($file){ $fp = fopen($file, w  fwrite($fp, $this- file ()); fclose($fp);}

2.實例

$dfile = tempnam( /tmp , tmp //產生一個臨時文件，用于緩存下載文件$zip = new /Org/Util/Zipfile();//----------------------$filename = 二維碼 .date( Y-m-d H:i ,time()). .zip //下載的默認文件名//以下是需要下載的圖片數組信息，將需要下載的圖片信息轉化為類似即可$params[ ids ] = explode( , ,$params[ ids //獲取圖片$image = array( array( image_src = pic1.jpg , image_name = 圖片1.jpg ), array( image_src = pic2.jpg , image_name = pic/圖片2.jpg ),foreach($image as $v){ $zip- add_file(file_get_contents($v[ image_src ]), $v[ image_name  // 添加打包的圖片，第一個參數是圖片內容，第二個參數是壓縮包里面的顯示的名稱, 可包含路徑 // 或是想打包整個目錄 用 $zip- add_path($image_path);//----------------------$zip- output($dfile);// 下載文件ob_clean();header( Pragma: public header( Last-Modified: .gmdate( D, d M Y H:i:s ) . GMT header( Cache-Control:no-store, no-cache, must-revalidate header( Cache-Control:pre-check=0, post-check=0, max-age=0 header( Content-Transfer-Encoding:binary header( Content-Encoding:none header( Content-type:multipart/form-data header( Content-Disposition:attachment; filename= .$filename. //設置下載的默認文件名header( Content-length: . filesize($dfile));$fp = fopen($dfile, r while(connection_status() == 0 $buf = @fread($fp, 8192)){ echo $buf;fclose($fp);@unlink($dfile);@flush();@ob_flush();exit();

值得一提的是打包下載時中文文件夾或中文名出現亂碼時可用下面方法解決

$name = iconv( utf-8 , gb2312 ,$name);
