Question : FTP Upload

I have a website, and occasionally, a customer needs to give me their file.  What is the best, most easiest and most user friendliest way to accomplish this off of my website?  My website is a classic asp website, but obviously, I would probably want something in asp.net for the upload functionality.  I know there are some third party controls out there, but I'm looking for something very easy and simple, and i don't mind paying for it.

Basically, i just want a page, where they need to enter a password, and then they can upload their file and there is a status bar or something telling them that its uploading.

Answer : FTP Upload

Assuming that the zipcode is always 5 numbers long, and preceeded by a space, this works:

$string="Anywhere, OH 12345";
$zip = substr($string,strrpos($string," ")+1,5);
echo $zip;
