apache variables within a method

[vero67]

Hi,

I'm quite new with PHP, and I encounter following problem :

I'd like to test value of SERVER_NAME within a method of a class (database class) in order to connect as a different user to my database, depending on which virtual host used.
The variable appears to be empty, while it is correctly populated in the other scripts.
Is there a special way to invoke apache variables or other global php variables within a method of a class ?

Thanks.

Did you declare them using the global keyword in the function call?

function myfunc() {
global $SERVER_NAME;

echo $SERVER_NAME;
}

sorry, 'global' keyword wasn't described in my book (PHP Professionnel by Wrox).
Another way is by using GETENV function (not described either).

Thanks.
