[SOLVED] Global?

[DarkPrince2005]

Ok, strangee and stupid question regarding global variables...

 

if i declare a the country of a user as a global variable when he logs in, will it be stored in the system memory or something for the duration of his session. And will it then be available even though he'll be navigating back and forth between different pages?

You can use constants.... http://us2.php.net/manual/en/function.constant.php

No, making a variable a global variable only makes it availlable in the functions you're using it in your application, it won't make it availlable on other pages. Technically speaking it does save the variable somewhere in the memory because that's what happens when you declare a variable ... but not in the way you're asking for.

 

If you want to save some information from a user during his visit you can just save it in the session ... pretty logical ain't it ? 

 

$_SESSION["country"] = "Belgium in my case ...";

 

I hope this gets you on your way ...

And don't forget to call session_start()!
