我从 dompdf 生成了多个 pdf，但如何在本地保存这些文件

Question

我从 dompdf 生成了多个 pdf，但我如何在本地保存这些文件，因为这些文件只能在网络浏览器中打开。如何将它们保存到服务器中？

我的代码

include '../../libs/vendor/autoload.php';
include '../../libs/dompdf/autoload.inc.php';


use Dompdf\Dompdf;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();

if (isset($_POST['submit'])) {

    if (isset($_FILES['challan']['tmp_name'])) {
        $challan = $_FILES['challan']['tmp_name'];

        $spreadsheet = $reader->load($challan);

        $sheetData = $spreadsheet->getActiveSheet()->toArray();

        if (!empty($sheetData)) {
            
              
        $html = ob_get_clean();
                $html = stripslashes($html);
                
                $html = <<<HTML
                  <html>
                      <head>
                            <style type="text/css">
                                /* Your document styling goes here */
                            </style>
                      </head>
                      <body>
                HTML;
                
                for ($i=0; $i<count($sheetData); $i++) {
                $name = $sheetData[$i][0];
                $fatherName = $sheetData[$i][1];
                $rollNo = $sheetData[$i][2];
                $class = $sheetData[$i][3];
                $dept = $sheetData[$i][4];
                $dompdf = new DOMPDF();
                $html .= '<p>Hello World</p>';
                $dompdf->load_html($html);
                $dompdf->render();
                file_put_contents('pdf', $dompdf->output());
                $dompdf->stream();
                }
      }
    }
}

我又更新了代码，请看一下

您可以使用方法 output() to get the PDF content and save into a file using file_get_contents():

file_put_contents('/path/to/file.pdf', $dompdf->output());

编辑问题更改后：

for ($i=0; $i<count($sheetData); $i++) 
{
    $dompdf = new DOMPDF();
    $dompdf->load_html($html);

    $dompdf->render();
    file_put_contents('pdf' . $i . '.pdf', $dompdf->output());
    $dompdf->stream();
}

但是生成N次，同一个PDF好像很奇怪
