GLOBAL variable

[eluser]dannythebestguy[/eluser]
I needed some help to write the GLOBAL variable which I can use it in the application. I read in some post that it can be done through libraries and config file. Can somebody help me by showing how exactly it can be done.

Appreciated...

What information does said variable hold? What is its context? In general, yeah, a config file is probably the easiest to use for something like this.

[eluser]dannythebestguy[/eluser]
It is a sort of a counter. Everytime the function is executed the value changes to $x++. This value has to be then put to the view.

If that counter is available to only 1 user, use a session. If that counter is available to all users, store that in a database field.

Are you a PHP person Danny?

The problem with trying to use a variable is that they only exist for that user. In other words, if 2 people are on your site, and each increments the variable 5 times, they'll each see "5" and not "10". Your only real options for sharing data between users when that data needs to change is either (1) using a database; (2) saving your information to files.

File writing is considerably slower then database access, but depending on how busy your site is, it could still work.

Hello Derek,

Oh yes.. I am a hardcore PHP guy... working as a consultant for a Bank...

And this is what I am looking for... for each user the value has to be 5 and not 10. So a user logs in runs the function for x number of times and prints that number... Nothing to do with how many other users are logged in... Means it is a counter per user.

[eluser]Derek Allard[/eluser]
Well my advice doesn't change then.

If that counter is available to only 1 user, use a session.

[eluser]dannythebestguy[/eluser]
OK.. but the problem is I will be using 6 variables which change as per a function which has a switch function inside. So I will have to create 6 sessions which again I think wont be a good idea.. But having 6 Global variable will solve the problem... Plz advice..

Thnx
