Global Variable - assistance required please

[Geordie_Blue]

Hi all,

Looking for some help.

I have a website that currently focusses on local information based on one particular region of the UK and without going into subdomains etc. I want to expand the site to include another region, displaying information from my database, based on the region that the user decides to view.

I use a "head.inc" file to keep banner and menus the same on every page and want to add a drop down menu to this file, so the user can select to change region from anywhere in site and then any subsequent pages they go to will view info based on that choice until they change it.

Can I do this using a global variable? e.g. $area

I envisage this being set by default when the site is opened to area 1, but then a drop down menu which would chenge it between 1 and 2, depending on the users choice......then amending all my queries to include the area = $area

Any help anyone can give will be greatly appreciated.

Use sessions or cookies. THey're already global and are easier to work with.

[man]session_start/man
[man]set_cookie/man

Excellent. Many thanks bpat1434

One last thing...I know I know...being lazy....but is there a global variable that exists automatically that holds the current web page name?

I'm trying to do this in the "head.inc" file, and need to know the current page on the site so I can redisplay it after changing the area that the user is viewing details for.

Over on php.net search the online documentation for $_SERVER predefined variables
