It's fairly easy. $_FILES is an array that holds any uploaded files. Each item in $_FILES has:
name - The name of the file
type - The mime type
size - The filesize in bytes
tmp_name - The path to the temp location it was uploaded to
Basically all you have to do is move the file from the temp location to where you want it. PHP provides move_uploaded_file specifically for this (while also making sure it is a valid uploaded file [security]).
Here's an example page I made up for you. Note that form has enctype="multipart/form-data". This is to tell PHP to process the upload. Otherwise, you'd need to manually parse $HTTP_RAW_POST_DATA -- eew!
In this example, it uploads the files to ./uploads/. The filename is a pretty random 32 character (used by md5'ing a combo of the md5 check sum of the file itself, and a random integer from 1-9999).
[php]<?php
$page =& new uploadForm();
/**
* Container class for the upload page
*/
class uploadForm
{
/**
* Directory to save files to
* @access private
* @var string
*/
var $save_dir;
/**
* Constructor; Decide on which action to take
* @param string $save_dir The directory to save files to (with trailing slash)
*/
function uploadForm($save_dir = './uploads/')
{
$this->save_dir = $save_dir;
