Just a humble question regarding php email attachment script

Hello Everyone.
Does anybody know how do I basically use the php email attachment script? I mean, do I use it as a script of an filling form that I have to create my self or do i just save code as a php file and upload it to the server for use?
If the way to use is to save code as a php file and put it to the server, after that I just have to execute it with Internet Explorer?
Configuring this script is little unusual so could anyone just send me en example of one with all needed variables settled so I will just modify them to feat my server parameters?
Tanx a lot in advance!
Regards,
