global variable in PHP to store users input ???

[trinh]

My problem is:
- I'd like to create a global variable (in PHP of course) to store the value of a submitted field so that (the global variable) is available to any other users from other clients acess to my site. Its something like "application variable" in ASP, but I wonder how to do it in PHP.

Anybody can help me out of this problem ?

you can store the value externally e.g. in a file or database.
