我想将html文件转换为pdf文件。我在我的电脑上安装了wkhtmltopdf。我有以下代码将html文件转换为pdf文件。
$data = '<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<h1>Lorem Ipsum</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quod laboriosam atque, consequuntur beatae fugiat in incidunt perspiciatis dolorem ipsum nam itaque animi nobis quam illum dolore. Nam nostrum maiores, ipsa.</p>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ipsa vero veniam sed ullam commodi! Accusantium, officia vitae, adipisci mollitia, blanditiis voluptates accusamus nam atque repellendus laborum, ullam vel eligendi esse?</p>
</body>
</html>';
file_put_contents('test.html', $data);
$html_file_url = 'http://localhost/document-editor/test.html'; // html file
$pdf_file_url = 'C:\\test.pdf'; // pdf file
//$cmd = "C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf http://localhost/";//$html_file_url $pdf_file_url";// command
$cmd = "c:\Program Files\wkhtmltopdf\bin\wkhtmltopdf $html_file_url $pdf_file_url";// command
//c:\Program Files\wkhtmltopdf\bin\wkhtmltopdf
exec($cmd);
