Usage /upload , read the information in the script.

/*
How the script is currently configured it works like this (EXAMPLE):
-The user types '/upload test.exe' (test.exe is in the mirc dir)
-The script will submit the file to www.google.com/upload.php
-The php file will move the file 'test.exe' to the dir 'upload/'
-The file can be found at 'www.google.com/upload/test.exe'
-This is an example

-- CONTENT OF THE PHP FILE NAMED 'upload.php' (remember the mirc script must point to this file --
<?php
//Set uploaddir, remember that for that folder you must set read+write permission,
//look for the command CHMOD and set the permissions in the folder to '777'
$uploaddir = "upload/";

$file = $uploaddir . $_FILES['uploadfile']['name'];
move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)
?>
