The Problem is when i click on the button it redirects me to the pdf file but it gives me the error and the error is 'Failed to load PDF document'.You can see the error below.What am i doing wrong??

Answer 1

Make things simple:
<?php
include("mpdf/mpdf.php");
echo '<table border="1">';
echo '<tr><td>Put some content here!</td></tr>';
echo '</table>';
$html = ob_get_contents();
$filename = 'filename.pdf';
$mpdf = new mPDF('utf-8', 'A4-P');
$mpdf->WriteHTML($html);
$mpdf->Output($filename,'I');
Don't need to convert charset, this library is already running in UTF-8.
