File Size Calculated but File Not Found - php

Question

I am trying to install the "Waiting time file download script using php and jquery" script found at http://www.w3webtools.com/simple-page-download-file-using-php-and-jquery/
I have downloaded the demo scripts and installed them in my server at /var/www/test/.
When I try to call the demo files it recognizes the file size but says the file is not found. http://4x4submods.tk/test/download.php?f=advance-security-login-system-using-php-mysql.zip
Any ideas?
mod_rewrite is enabled.

This works:
<?php
header('Content-Type: text/html;charset=UTF-8');
include 'include/config.php';
include 'include/function.php';
?>
<!-- Edited to point to the latest copy of jquery! -->
<script src="http://code.jquery.com/jquery-2.0.0.js"></script><?php
$fname='hello.txt';
$download=1;
if(!file_exists(UPLOAD_DIR.'/'.$fname))
{
$download=0;
}
$downloadLink='download/'.makeHash($fname).'/'.$fname;
function file_size($url){
$size = filesize($url);
if($size >= 1073741824){
$fileSize = round($size/1024/1024/1024,1) . 'GB';
}elseif($size >= 1048576){
$fileSize = round($size/1024/1024,1) . 'MB';
}elseif($size >= 1024){
$fileSize = round($size/1024,1) . 'KB';
}else{
$fileSize = $size . ' bytes';
}
return $fileSize;
}
?>
<div class="container">

Function.php file:
<?php
function makeHash($fileName)
{
return md5( $fileName . SECURITY_CODE );
}
function verifyHash($fileName,$hashCode)
{
return $hashCode==makeHash($fileName);
}
Ensure that you use the same hash that you used in the key when decoding!
The rest was not really required and made it more complicated than necessary!
Including the file date in the hash, may make it not work if the file date changes for some reason, for example, if you need to do a system restore. You can probably put the server name back in the hash if you think you really want it!
