Solution: The idea is to create a index.php and put all the required facebook og:image and then redirect the page to show.php

Show.php will send the appropriate headers so that the pdf will be viewed in the respective browser.

    1. index.php
    2. show.php
    3. title.jpg
    4. test.pdf
  2. index.php
    1. <!DOCTYPE html>
      <html lang=”en”><head>
      <meta charset=”utf-8″>
      <meta http-equiv=”X-UA-Compatible” content=”IE=edge”>
      <meta name=”viewport” content=”width=device-width, initial-scale=1″>
      <meta name=”keywords” content=””>
      <meta name=”keywords” content=””>
      <meta name=”description” content=””>
      <meta name=”author” content=””>

      <meta property=”og:type” content=”website” />
      <meta property=”og:title” content=”xxxxx” />
      <meta property=”og:site_name” content=”xxxxx” />
      <meta property=”og:description” content=”xxxxx” />
      <meta property=”og:image” content=”https://abcd.com/article/title.jpg”>

      <title>test</title>
      <link href=”xxxx” rel=”shortcut icon” type=”image/ico” />

      </head>
      <script>location.href=”show.php”; </script>

  3. show.php
    1. <?php// Store the file name into variable
      $file = ‘test.pdf’;
      $filename = ‘test.pdf’;

      // Header content type
      header(‘Content-type: application/pdf’);

      header(‘Content-Disposition: inline; filename=”‘ . $filename . ‘”‘);

      header(‘Content-Transfer-Encoding: binary’);

      header(‘Accept-Ranges: bytes’);
