<form action="file.php" method="POST" >
  <input name="file_name" value="cv.pdf" type="hidden">
  <input type="submit" value="Download CV">
</form>

Answer 1

No need of all that. Just try this:

<a href="/files/yourfullPathOnTheServer.format" download>

You can replace a href with button :)

Answer 2

try with this if you want to download pdf using php code,set file path to $file

<?php
 $file = 'filename.pdf';
 if(!file){
     die('Error: file not found');
 }else{
     header("Cache-Control: public");
     header("Content-Description: File Transfer");
     header("Content-Disposition: attachment; filename=$file");
     header("Content-Type: application/pdf");
     header("Content-Transfer-Encoding: binary");
     readfile($file);
 }
 ?>

Answer 3

You need to just change the below code

header('Content-Disposition: attachament; filename: " .$files"');

with this:

header("Content-Disposition: attachament; filename: '$files'");

Also remember that

It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem)
