php - Cannot read pdf generated through dompdf in chrome -

i'm testing dompdf. , found out i'm generating can't red chrome. tried open sumatra pdf reader, , opened. tried opening random pdf file ebooks in chrome , red it. there wrong code chrome wasn't able read it:

<?php require_once("dompdf/dompdf_config.inc.php");  $dompdf = new dompdf();  $d_r = array(array('name'=>'ab', 'course'=>'bsit'), array('name'=>'yoh', 'course'=>'bscs'));  ob_start(); put_table($d_r); file_put_contents('sample.html', ob_get_contents()); generate_pdf('sample.html');  function put_table($raw_data){ ?> <table border="1">     <tr>     <th>name</th>     <th>course</th>     </tr>  <?php foreach($raw_data $data){ ?>        <tr>     <td><?php echo $data['name']; ?></td>     <td><?php echo $data['course']; ?></td>     </tr> <?php } ?> </table>       <?php }   function generate_pdf($filename){     global $dompdf;      $dompdf->load_html(file_get_contents($filename));     $dompdf->render();     $dompdf->stream($filename. ".pdf");  } ?> 

the pdf may have been rendered correctly but, depending on server configuration, non-pdf content may have been included in pdf source. pdf readers more lenient others , discard non-pdf content. easiest way check open pdf in text editor , things strings of html text.

if that's not problem, see pdf itself.
