Php 批量选择文件-压缩文件-然后下载到客户端

当我试图用我需要做的事情来寻找解决方案时，我似乎无法从我所发现的东西中得到任何东西

我正在尝试创建一个表单，用户可以在其中选择网页上列出的1个或多个（批量选择全部）pdf文件

当用户单击submit时，我想让我的PHP下载文件创建一个zip文件，将选定的pdf文件（存储在服务器上）添加到zip文件，然后强制将zip文件下载给最终用户

当用户打开zip文件时，他们从网页表单中选择的pdf文件将在那里供其使用

我发现的一切要么不起作用，要么不安全，要么与我不想先上传文件有关。这些文件已存储在我的服务器上

任何帮助都将不胜感激

<code>
$files = array($_POST['file']);


        $zip = new ZipArchive();
        $filename = "practiceforms";
        $zip->open($filename,  ZipArchive::CREATE);
        foreach ($_POST['file'] as $key => $val)  {
          echo $path = "/images/docs/solutions/".$val.".pdf";
          if(file_exists($path)){
              $zip->addFile(basename($path),  file_get_contents($path));
          //$zip->addFromString(basename($path),  file_get_contents($path));  
          }
          else{
           echo"file does not exist";
          }
        }
        $zip->close();

        echo header('Content-Length: ' . filesize($filename));
        exit;
</code>

这些错误有助于：

error_reporting(E_ALL);
ini_set('display_errors', '1');

尝试：

您可能还需要

.zip

扩展名：

$filename = "practiceforms.zip";

然后，在发送正确的标题后，您将需要以下内容将文件内容发送到浏览器：

readfile($filename);

这是我的最终工作版本-让我知道，如果你有任何关于精简它的建议。同时，非常感谢您的支持和投入

您有什么东西吗？可能是表单？我的表单只是一个基本数组-eCard
