How to show a PDF in a Browser – PHP – Chrome – Header

Requirement:

To show a pdf in a website. Also show the facebook image while sharing.

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.

Folder Structure /website.com/article
1. index.php
2. show.php
3. title.jpg
4. test.pdf
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>
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’);
  
  // Read the file
  @readfile($file);
  ?>
