hyperlink - PHP Force Download Help

I've been wrestling around with this for awhile now. I am trying to make it so when a user click a link it will force a download. Here's my code so far:

<?php
function Download()
{
    $fullpath = $_SERVER['DOCUMENT_ROOT']."front.dwg"; //Full path of document
$filename = "front.dwg";  //Document file nmae


  $mm_type="application/octet-stream";

    header("Cache-Control: public, must-revalidate");
    header("Pragma: hack");
    header("Content-Type: " . $mm_type);
    header("Content-Length: " .(string)(filesize($fullpath)) );
    header('Content-Disposition: attachment; filename="'.$filename.'"');
    header("Content-Transfer-Encoding: binary
");
}
?>

<html>
<body>

<a href="#" onclick="<?php Download() ?>">Test</a>

</body>
</html>

Your going to need to pull out your function and save it as "download.php"

Then just have a link that goes to it:

<a href="download.php">

Download.php should look like this:

$fullpath = $_SERVER['DOCUMENT_ROOT']."front.dwg"; //Full path of document
$filename = "front.dwg";  //Document file nmae


 $mm_type="application/octet-stream";

   header("Cache-Control: public, must-revalidate");
   header("Pragma: hack");
   header("Content-Type: " . $mm_type);
   header("Content-Length: " .(string)(filesize($fullpath)) );
   header('Content-Disposition: attachment; filename="'.$filename.'"');
   header("Content-Transfer-Encoding: binary
");
