Well what this file is thought to do is create porn popups. It most likely was caught while browsing through the internet, making it able to be produced through the server.

could be info for popup

w=1024 width
h=768 height
t=0 toolbar
l=0 links
i=109 id number?
c=1 not sure

but as mentioned php files are produced after being served, so unless you can ftp the .php file your just seeing the results.
if the [popup] had a end tag it could of been xml

Without having knowledge of the file, your friends computer, or his actions it is impossible to really know what any of this means. We dont even know the symptoms. Also. How do you know it was a php file. Php files only execute under a server call like in apache, not if you just open them in notepad.
