启用生成pdf（它给我计划文件中的html文本） - dompdf

Question

$content['profile_data'] = file_get_contents(base64_decode($profile_data,true));
$pdf = PDF::loadHtml(htmlentities($content['profile_data']));
$pdf->setOptions(['setIsHtml5ParserEnabled'=>true]);
// $pdf->setPaper('A4','landscape');
$pdf->stream();
$pdf->save($path . '/' . $file_name.'.pdf');

整个代码看起来没问题。来自 url 的 html。我正在尝试将其保存为 pdf 格式的文件。

但是当我尝试打开它时，它给了我一个计划文本 HTML。请帮帮我

谢谢

您不渲染 (->render())。

简短示例：

$html = ''; // Your html.
$size = 'A4';
$orientation = 'portrait';
$options = new Options(
    [
        'isHtml5ParserEnabled'    => true, // little faster
    ]
);
$domPdf = new Dompdf($options);
$domPdf->loadHtml($html);
$domPdf->setPaper($size, $orientation);
$domPdf->render();
$pdf = $domPdf->output();

我在这里发布我使用 dompdf 所做的所有事情 -
我搜索了很多，很多边做边学......也许有帮助：

以下适用于版本v0.8.6

public function htmlToPdf($html, $size = 'A4', $orientation = 'portrait')
{
    $options = new Options(
        [
            //'logOutputFile'           => 'data/log.htm',
            'isPhpEnabled'            => false,

    $domPdf = new Dompdf($options);
    $domPdf->loadHtml($this->minimizeHtml($html));
    $domPdf->setPaper($size, $orientation);
    $domPdf->render();
    return $domPdf->output();
