I have a class that contains a form, when the form is submitted it 
posts back to the class.  The class is included inside of another file, 
so all of the form variables need to be declared as global in order to 
access their values.

On the form are several check boxes (number undetermined until the 
script is run) and the only way I know to access these values is using 
the "variable variables" feature of PHP, as follows:

$A = "chkContact".$I;
$B = $$A;

This would work just fine if $chkContact## was not a global variable 
(ie..not wrapped inside of a class).  How can I use variable variables 
on a global variable?
