我有这个简单的HTML文件（simple.html）来测试DomPDF：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
<title>Bootstrap 101 Template</title>
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">

</html>
这是我的 DomPDF 生成器文件：
<?php
require_once '../../../lib/dompdf/autoload.inc.php';
use Dompdf'Dompdf;
// instantiate and use the dompdf class
$dompdf = new Dompdf();
$invoice = file_get_contents('invoice.html');
$dompdf->loadHtml($invoice);
// (Optional) Setup the paper size and orientation
$dompdf->setPaper('A4', 'portrait');
// Render the HTML as PDF
$dompdf->render();
// Output the generated PDF to Browser
$dompdf->stream();
?>
这是错误消息...
Warning: fopen(/home/***/lib/dompdf/lib/fonts/345658495770f44fa67e0e37c1b01eb4.ufm): failed to open stream: Permission denied in /home/***/lib/dompdf/lib/php-font-lib/src/FontLib/AdobeFontMetrics.php on line 45
Warning: fwrite() expects parameter 1 to be resource, boolean given in /home/***/lib/dompdf/lib/php-font-lib/src/FontLib/AdobeFontMetrics.php on line 191
为什么 PHP 无法打开/lib/dompdf/lib/fonts 文件夹？ 它已经拥有drwxrwxr-x权限。
为什么我在那里看不到任何345658495770f44fa67e0e37c1b01eb4.ufm文件？
谢谢
我尝试将所有需要的html保存在变量$html中，然后使用
$dompdf->loadHtml(html_entity_decode($html));
从外部文件中获取 html 时，它也应该有效。尝试更换线路
$dompdf->loadHtml($invoice);
跟
$dompdf->loadHtml(html_entity_decode($invoice));
