DOMPDF not working

I am trying to take some html from a textarea and convert it to a pdf. I donwnloaded DOMPDF from https://github.com/dompdf/dompdf and wrote the code below. When I click submit I get this error: "Internal Server Error". (my webhost doesn't tell me which line it's one) (the name of this file is test2.php)

<?php
if (isset($_POST['submit'])) {
$content = $_POST['content'];
if (empty($content)){
    $error = 'write something';
}
else {
    include_once( 'dompdf/dompdf_config.inc.php' );
    $dompdf = new DOMPDF();
    $dompdf->load_html($content);
    $dompdf->render();
    $dompdf->stream('example.pdf');
}
}


?>
<!DOCTYPE html>
<head>

</head>
<body>
<?php
if(isset($error)){
echo $error;
}
?>
<form method="post" action="test2.php">
<textarea name="content" id="content">hello world</textarea><br>
<input type="submit" name="submit" value='submit'>
</form>
</body>
</html>

I was struggled for more than one month to solve this. Finally I solved it. the solution is below.

<?php
require_once 'dompdf/autoload.inc.php';
// reference the Dompdf namespace
use Dompdf\Dompdf;
?>
<html>
  <head></head>
  <body>
    <h1>Sucess</h1>
  </body>
</html>
<?php

$html = ob_get_clean();
$dompdf = new DOMPDF();
$dompdf->setPaper('A4', 'portrait');
//$dompdf->setPaper('A4', 'landscape');
$dompdf->load_html($html);
$dompdf->render();
//For view
$dompdf->stream("",array("Attachment" => false));
// for download
//$dompdf->stream("sample.pdf");

?>

I had a similar issue on a client's server when using DOMPDF for a project.

It's possible that you do not have the right level of error reporting configured with your installation of PHP.

At the top of your script place the following; error_reporting(E_ALL);

Example:

error_reporting(E_ALL);
if (isset($_POST['submit'])) {
$content = $_POST['content'];
if (empty($content)){
    $error = 'write something';
}
else {
    include_once( 'dompdf/dompdf_config.inc.php' );
    $dompdf = new DOMPDF();
    $dompdf->load_html($content);
    $dompdf->render();
    $dompdf->stream('example.pdf');
}
}

You should now see a more detailed message about the type of error received.

There could be issues with the HTML markup you are passing to the $dompdf->load_html($content); method or alternatively you might be experiencing memory related issues (exceeding your memory allowance).

Typically these errors will report themselves but again depending on your setup, reporting might be limited.
