我正在使用 dompdf 从 php 文件生成 PDF。这是文件的完整代码：

<?php 

// INCLUDEM CONFIGUL SI INITIALIZAM CLASELE DE SISTEM
require_once 'config.php';
require_once 'initialize.php';
require_once("/dompdf/dompdf_config.inc.php");

// Database
// Conectarea LA BAZA DE DATE !!!
$db = new MySQLDatabase();

// Session
// SESIUNEA CARE TINE UTILIZATORUL LOGAT !
$session=new Session();      
?>

<?php
$html = ob_get_clean();
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();

?>

dompdf 只生成了 HTML 部分，但没有显示 php 部分。在配置中，DOM_ENABLE_PHP 设置为 true。可能是什么问题？

看起来您正在尝试捕获所有输出（至少，这是我认为从您的ob_get_clean();使用中找到的。但是您从不调用ob_start，因此您可能只是将所有数据推送到浏览器/输出，而一无所获那里。

只需在字符串中构建您的 html，然后将其用于输入。

尝试这个

<?php 
require_once 'config.php';
require_once 'initialize.php';
require_once("/dompdf/dompdf_config.inc.php");

$db = new MySQLDatabase();
$session=new Session();      

$html =  <<<HTML
<html>
<head>
</head>
<body>
<div>
<p>
test
</p>
</div>
</body>
</html>
HTML;

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("factura.pdf");

?>

您将所有 PHP 生成的输出存储到$categoriile. 然后您正在检查是否未设置$session->data['finalizat']...也许您不满足此条件。检查$session->data['finalizat']。您也没有 ob_start （根据 Nanne 的通知）
