How to package and download multiple files in PHP

This article mainly introduces the method of packaging and downloading multiple files in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

When multiple files need to be downloaded at the same time, most browsers do not support simultaneous downloading of multiple files. JavaScript scripts can be used to dynamically generate multiple links, but this requires the user to click the download dialog box multiple times, resulting in a poor user experience. , and some browsers are not yet compatible. At this time, multiple file package downloads can help you solve this problem.

$filename = "test.zip";
$datalist=array('./pubfile/1.jpg','./pubfile/2.jpg');
if(!file_exists($filename)){
 $zip = new ZipArchive();
 if ($zip->open($filename, ZipArchive::CREATE)==TRUE) {
  foreach( $datalist as $val){
   if(file_exists($val)){
    $zip->addFile( $val, basename($val));
   }
  }
  $zip->close();
 }
}
if(!file_exists($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
@readfile($filename);
