PHP File Upload Code:

<form enctype=”multipart/form-data” action=”<? echo $_SERVER[‘PHP_SELF’]; ?>” method=”post”>

    <input type=”hidden” name=”MAX_FILE_SIZE” value=”1000000″>
    <input type=”hidden” name=”myhid” value =”hi”>
    <style type=”text/css”>

PHP File Download Code:

$filepath = $_SERVER[‘DOCUMENT_ROOT’].”/uploads/”.$myfilename;
if (file_exists($filepath)) {
//download application
   header(“Content-Type: application/force-download”);
   //the filename will be given below
   header(‘Content-Description: File Transfer’);
    header(‘Content-Type: application/octet-stream’);
    header(‘Content-Disposition: attachment; filename=’.basename($myfilename));
    header(‘Content-Transfer-Encoding: binary’);
    header(‘Expires: 0’);
    header(‘Cache-Control: must-revalidate’);
    header(‘Pragma: public’);
//open file in binary mode  
$my_file = fopen($filepath, ‘rb’);
//output data
//close file
