php - Unable to display pdf on android localhost -


i've been using ksweb's phpfilemanager tool host images on android tablet while , have tried expand capacity .pdf files. unfortunately given file manager opens in browser on android, unable view pdfs.

since local, using google docs doesn't work , when try view in alternative browser such dolphin pdf viewer plugin, displays blue box question mark inside apparently indicates file unable found.

here's code i'm using in localhost reference.

<head>  <title> title goes here </title>  <?php $a = array(); $dir = 'filenameinphpfilemanagerdirectory'; if ($handle = opendir($dir)) {      while (false !== ($file = readdir($handle))) {         if (preg_match("/\.png$/", $file)) $a[] = $file;         elseif (preg_match("/\.jpg$/", $file)) $a[] = $file;         elseif (preg_match("/\.jpeg$/", $file)) $a[] = $file;         elseif (preg_match("/\.pdf$/", $file)) $a[] = $file;      }      closedir($handle); } foreach ($a $i) {      echo "<img src='" . $dir . '/' . $i . "' />"; } ?>
