Php Globals?

[Gwayn]

Hi all, i got a question: i'm creating a cms, i want to handle the language choose, and i thought to handle it by setting a variable in the index.php... a variable that every other script and page can read. Now, i think it can be done using globals, but how? If i define "global $var;" in index.php, the other scripts do not see that variable... so how can i do?

Thanks for the help.
Bye, Stefano.

Global variables are script-wide, outside of functions and classes. When a script ends, global variables are destroyed. The keyword "global" is used only in functions to import global variables of the currently running script into function scope.

To do what you want you'll need to use persistent storage, such as database tables or configuration files, or use sessions or get/post techniques.

Uhm.. so i'm thinking about using $_REQUEST (send data via url like: script.php?lang=eng) or COOCKIES or SESSION... i need an advise...

Any of those should work fine, mostly. If the user has cookies disabled then cookies won't work of course, and neither will sessions if you have "session.use_only_cookies" on. You'll want to specify a default and/or a "set language" link on all pages, e.g. if using the "$_GET" array and the user accesses a page out of order so that the language query isn't there.
