ZipArchive 打包下载压缩包

用php的header()方式下载压缩包。

要点：1、不能在header导出压缩包前向浏览器输出内容，否则文件下载压缩包成功，打开的压缩包也会显示被破坏。

         2、在压缩文件包的php代码前不可以有js脚本、meta的加载，否则解压会显示损坏。

<?php 
if(isset($_POST['mac']))
{
     // print_r($_POST);

     $mac = $_POST['mac'];
     $date = $_POST['date'];
     $version = $_POST['version'];

     $mac = preg_replace("/[:-]/","", $mac);
     $version = preg_replace("/./","",$version);
    
    //获取文件列表
    function list_dir($dir){
            $result = array();
            if (is_dir($dir)){
                $file_dir = scandir($dir);
                foreach($file_dir as $file){
                    if ($file == '.' || $file == '..'){
                        continue;
                    }
                    elseif (is_dir($dir."/".$file)){
                        $result = array_merge($result, list_dir($dir."/".$file));
                    }
                    else{
                        array_push($result, $dir."/".$file);
                    }
                }
            }
            return $result;
        }

    //获取列表 
    $datalist=list_dir('./package');
    // print_r($datalist);
    // die();
    $filename = "JD_".$mac."_".$version."_".$date.".zip"; //最终生成的文件名（含路径）   
    if(!file_exists($filename)){   
         //重新生成文件   
        $zip = new ZipArchive();//使用本类，linux需开启zlib，windows需取消php_zip.dll前的注释   
        if ($zip->open($filename, ZIPARCHIVE::OVERWRITE)!==TRUE) {   
            exit('无法打开文件，或者文件创建失败');
        }   

        foreach( $datalist as $val){   
            if(file_exists($val)){   

                $zip->addFile($val, basename($val));//第二个参数是放在压缩包中的文件名称，如果文件可能会有重复，就需要注意一下   
            }   
        }   
        $zip->close();//关闭   
    }   

    //即使创建，仍有可能失败。。。。   
    if(!file_exists($filename)){   
        exit("无法找到文件"); 
    }   
   


  header("Cache-Control: public"); 
  header("Content-Description: File Transfer"); 
  header('Content-disposition: attachment; filename='.basename($filename)); //文件名   
  header("Content-Type: application/zip"); //zip格式的   
  header("Content-Transfer-Encoding: binary"); //告诉浏览器，这是二进制文件    
  header('Content-Length: '. filesize($filename)); //告诉浏览器，文件大小
