1. First is we make a class download .php
<?php
/*
|-----------------
| Chip Download Class
|------------------
*/
require_once("class.chip_download.php");
/*
|-----------------
| Class Instance
|------------------
*/
$directori = $_GET['dir'];
$file = $_GET['f'];
$tipe = $_GET['tipe'];
$download_path = "C:wamp/www/FileManagerUsingPHP".$directori.'/';
$args = array(
'download_path' => $download_path,
'file' => $file,
'extension_check' => TRUE,
'referrer_check' => FALSE,
'referrer' => NULL,
);
$download = new chip_download( $args );
/*
|-----------------
| Pre Download Hook
|------------------
*/
$download_hook = $download->get_download_hook();
//$download->chip_print($download_hook);
//exit;
/*
|-----------------
| Download
|------------------
*/
if( $download_hook['download'] == TRUE ) {
/* You can write your logic before proceeding to download */
/* Let's download file */
$download->get_download();
}
?>
2. See, that the download.php require a class, class.chip_download.php
This is the class.chip_download.php

If you want to see the complete code klik here
For more information, before you upload your file into a directory, make sure that your file name does not consist of space (" ").
So, before uploading the file, replace all the file name which is consist of space (" ") with _, or anything.
Because, this download code only works well with file name which is not consist of space (" ").
Thank you..
