Pass variable from Template to PHP

[neof]

Thanks I need to know the user's current pages' info such as Forum Title, so I am guessing that I have to get the info from the template, because the external php script don't know what page the user is on. I think I get the info from the template, pass it to the php file, and the result of the php file is passed back into template to display to user. Pls let me know if there is other method to process the forumtitle for each user.
