嗨，我在我的网站上安装了 mybb。我还安装了 dompdf 并且它在它自己的目录中工作，即我已经安装在"DOM"目录中。现在我可以用这个简单的代码轻松地通用 pdf，保存在"DOM"目录中。
<?php
require_once "dompdf_config.inc.php";
//$file = "www/test/css_at_font_face.html";
$file="msf.html";
$dompdf = new DOMPDF();
$dompdf->load_html_file($file);
$dompdf->render();
$dompdf->stream("sample.pdf");
?>
如果我尝试访问不在目录中的其他文件，DOM即
load_html_file($file); $dompdf->渲染（）；$dompdf->stream("sample.pdf");
?> 我收到错误Remote file requested, but DOMPDF_ENABLE_REMOTE is false
要启用远程访问，请勿编辑“dompdf_config.inc.php”
改用：
$dompdf = new DOMPDF();
$dompdf->set_option('enable_remote', TRUE);
$dompdf->set_option('enable_css_float', TRUE);
$dompdf->set_option('enable_html5_parser', FALSE);
在不启用远程文件访问的情况下加载 html：
<?php
require_once "dompdf_config.inc.php";
$file = "www/test/css_at_font_face.html";
$html=file_get_contents($file);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");
?>
要启用远程文件访问：
取自 dompdf_config.inc.php
/**
* Enable remote file access
*
* If this setting is set to true, DOMPDF will access remote sites for
* images and CSS files as required.
* This is required for part of test case www/test/image_variants.html through www/examples.php
*
* Attention!
* **This can be a security risk**, in particular in combination with DOMPDF_ENABLE_PHP and
* allowing remote access to dompdf.php or on allowing remote html code to be passed to
* $dompdf = new DOMPDF(); $dompdf->load_html(...);
* This allows anonymous users to download legally doubtful internet content which on
* tracing back appears to being downloaded by your server, or allows malicious php code
* in remote html pages to be executed by your server with your account privileges.
*
* @var bool
