【问题描述】：
我有一个 PHP 页面，它从页面本身显示的数据库中检索各种数据。我想生成包含内容的 PDF 文件并将该文件保存在服务器中以备后用。我的 PHP 页面在浏览器中完美呈现。
我尝试使用 header('Content-disposition: attachment; filename=filename.pdf');，但收到错误 Failed to load PDF document.
我也尝试了dompdf，但最终得到了空白的 pdf 文档。
由于该文件包含一些敏感数据，我不会冒险将内容发送到第三方服务器。请帮帮我。
我的文件主要包含 PHP 和 CSS。
<?php
include('php-include/connect.php');
if(isset($_GET['purpose']) && isset($_GET['membership'])) {
$purpose = $_GET['purpose'];
$membership = $_GET['membership'];
if ($purpose == 'Volunteer Membership') {
$member_type = 'temporary';
$query = mysqli_query($con,"select * from temp_members where `membership`='$membership'");
if (mysqli_num_rows($query) > 0) {
while ($row = mysqli_fetch_array($query)) {
$name = $row['name'];
$email = $row['email'];
$address = $row['address'];
$city = $row['place'];
$state = $row['state'];
$country = $row['country'];
$pin = $row['pin'];
$bloodgroup = $row['bloodgroup'];
$dob = $row['dob'];
}
}
}
}
$count = substr($membership,-10);
$myDateTime = DateTime::createFromFormat('Y-m-d', $dob);
$dob = $myDateTime->format('d/m/Y');
$today = date('d/m/Y');
switch ($member_type) {
case 'temporary':
$validity = strtotime("+6 months");
$validity = date('d/m/Y', $validity);
break;
case 'default':
$validity = 'Lifetime';
}
?>

提前致谢。
