Put this script into download.php in the same folder as upload2.php, and invoke it as
http://localhost/phpsample/upload/download.php?file=FILE
where FILE is the filename that was uploaded.
<?php
$con = mysqli_connect("localhost","root","", "upload_db");
if (!$con) die('Could not connect: ' . mysqli_connect_error());
$name = $_GET['file'];
$query_filename = mysqli_real_escape_string($dbh, $name);
$src = 'E:\divya';
$data = mysqli_query($con, "select filename from upload_tb where filename = '$query_filename'");
if (mysqli_num_rows($data) ! 1) die ('File not uploaded: ' . htmlentities($name));
$path = "$src/$name";
http_send_content_disposition($name);
$type = mime_content_type($path);
http_send_content_type($type);
http_send_file($path);
exit;
?>
