When using include files it is important to note that global variables do not fit into the scope of
a included file...only the file that is calling the include will have access to global variables
(primarily enviroment & system variables like $HTTP_REFERER)!
I found it best to think of a include file as a completely separate php script. With it's own
variable scope.
TIP: You can pass your include files variables via the query string!
BASIC EXAMPLE:
$referer = explode("/",getenv("HTTP_REFERER"));
include("includefile.inc?referer=".$referer[2]);
### INCLUDEFILE.INC CONTENTS BELOW ###
if( $referer == "www.foo.com" )
print "Welcome foo!";
else
return;
