[PHP3] Accessing global variables from within a class From: Vamsi Nath (vnath <email protected>)
Date: 05/15/00

I have been having difficulty accessing global environmental variables like
$PHP_SELF and $HTTP_USER_AGENT from within a class. Normally, to use these
values in functions you have to specify them as 'global', but I get a parse
error when I try declaring a global variable within a class definition.

Example:

class Globals {
        global $PHP_SELF;

        function show_self() {
                print $PHP_SELF;
        }

}

Results in parse error:
Parse error: parse error, expecting `T_OLD_FUNCTION' or `T_FUNCTION' or
`T_VAR' or `'}''

The only way I have been able to get around this is to define a CONSTANT
outside the class definition.

Example:

define("PHP_SELF",$PHP_SELF);

class Globals {
        function show_self() {
                print $PHP_SELF;
        }
}

This works, but seems less then optimal. Is there a way around this?
Thanks for your help.
