ThinkPHP implements packaging local files into zip download_PHP tutorial

First, place the FileToZip.class file in the ThinkPHP/Extend/Library/ORG/Util/ folder. FileToZip.class.php is the zip download class, and its detailed code is as follows:

<&#63;php
/**
 * zip下载类文件
 * 遍历目录，打包成zip格式
 */
class traverseDir{
 public $currentdir;//当前目录
 public $filename;//文件名
 public $fileinfo;//用于保存当前目录下的所有文件名和目录名以及文件大小
 public $savepath;
 public function __construct($curpath,$savepath){
  $this->currentdir=$curpath;//返回当前目录
  $this->savepath=$savepath;//返回当前目录
 }  
 //遍历目录
 public function scandir($filepath){
  if (is_dir($filepath)){
    $arr=scandir($filepath);
    foreach ($arr as $k=>$v){
     $this->fileinfo[$v][]=$this->getfilesize($v);
    }
   }else {
    echo "<script>alert('当前目录不是有效目录');</script>";
   }
 }
 /**
  * 返回文件的大小
  *
  * @param string $filename 文件名
  * @return 文件大小(KB)
  */
 public function getfilesize($fname){
  return filesize($fname)/1024;
 }
 /**
  * 压缩文件(zip格式)
  */
 public function tozip($items){ 
  $zip=new ZipArchive();
  $zipname=date('YmdHis',time());
  if (!file_exists($zipname)){
   $zip->open($savepath.$zipname.'.zip',ZipArchive::OVERWRITE);//创建一个空的zip文件
   for ($i=0;$i<count($items);$i++){
    $zip->addFile($this->currentdir.'/'.$items[$i],$items[$i]);
   }
   $zip->close();
   $dw=new download($zipname.'.zip',$savepath); //下载文件
   $dw->getfiles();
   unlink($savepath.$zipname.'.zip'); //下载完成后要进行删除 
  }
 }
}
/**
 * 下载文件
 *
 */
class download{
 protected $_filename;
 protected $_filepath;
 protected $_filesize;//文件大小
 protected $savepath;//文件大小
 public function __construct($filename,$savepath){
  $this->_filename=$filename;
  $this->_filepath=$savepath.$filename;
 }
 //获取文件名
 public function getfilename(){
  return $this->_filename;
 }
 //获取文件路径（包含文件名）
 public function getfilepath(){
  return $this->_filepath;
 }
 //获取文件大小
 public function getfilesize(){
  return $this->_filesize=number_format(filesize($this->_filepath)/(1024*1024),2);//去小数点后两位
 }
 //下载文件的功能
 public function getfiles(){
  //检查文件是否存在
  if (file_exists($this->_filepath)){
   //打开文件
   $file = fopen($this->_filepath,"r");
   //返回的文件类型
   Header("Content-type: application/octet-stream");
   //按照字节大小返回
   Header("Accept-Ranges: bytes");
   //返回文件的大小
   Header("Accept-Length: ".filesize($this->_filepath));
   //这里对客户端的弹出对话框，对应的文件名
   Header("Content-Disposition: attachment; filename=".$this->_filename);
   //修改之前，一次性将数据传输给客户端
   echo fread($file, filesize($this->_filepath));
   //修改之后，一次只传输1024个字节的数据给客户端
   //向客户端回送数据
   $buffer=1024;//
   //判断文件是否读完
   while (!feof($file)) {
    //将文件读入内存
    $file_data=fread($file,$buffer);
    //每次向客户端回送1024个字节的数据
    echo $file_data;
   }
   fclose($file);
  }else {
   echo "<script>alert('对不起,您要下载的文件不存在');</script>";
  }
 }
}

The functional code for loading the zip download class FileToZip.class.php in ThinkPHP and implementing local file packaging and downloading is as follows:

import('ORG.Util.FileToZip');//引入zip下载类文件FileToZip
// 打包下载
$handler = opendir($cur_file); //$cur_file 文件所在目录
$download_file = array();
$i = 0;
while( ($filename = readdir($handler)) !== false ) {
 if($filename != '.' && $filename != '..') {
 $download_file[$i++] = $filename;
 }
}
closedir($handler);
$scandir=new traverseDir($cur_file,$save_path); //$save_path zip包文件目录
$scandir->tozip($download_file);
