Create a download button using html and php

Question

I want to create a download button using HTML and PHP. Below is my HTML code -

<!DOCTYPE html>
<html>
   <head>
       <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
   </head>
   <body>
       <form action="download.php" method="post">
           <input type="submit" name="submit" value="Download File" />
       </form>
   </body>
</html>

Now I have created another file, called "download.php" and kept it in the same directory as my HTML file. Code of the PHP file is given below -

<?php
  header('Content-Type: application/download');
  header('Content-Disposition: attachment; filename="Sample.mp3"');
  header("Content-Length: " . filesize("Sample.mp3"));
  $fp = fopen("Sample.mp3", "r");
  fpassthru($fp);
  fclose($fp);
?>

Sample.mp3 is kept in same folder as HTML file. I got these codes from internet.

Now my problem is, when I click on download button, content of the PHP file get opened rather than downloading the file.

Can anyone please help me to fix this issue.

Stupid questions perhaps but is PHP actually activated on the server? — hank

You need to run the script on:

A webserver
That supports PHP
That is configured to treat that file as PHP

You probably not run your .php file in a web server.

Please install a personal web server to your computer like XAMPP or WAMP
Then put your files into the www folder
Open your browser
Type localhost/your_HTML_file

Why should this work when the original code did not? What did you change and why?

using PHP is more coding need ! If you are using html5 and only do this for download purpose ,you can use <a> link,that is easy and simple

<!DOCTYPE html>
<html>
   <head>
       <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
   </head>
   <body>
      <a href="Sample.mp3" download>Download </a>
   </body>
</html>

Try this in php file:

$file = 'Sample.mp3'
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
