Re: [PHP-DEV] Why can constants only be scalars?

[Andi Gutmans]

No. At the time of introducing superglobals it was made clear this is only 
for internal use and not for script use. The main reason for introducing 
them was to make it easier to access $_GET, $_POST and friends mainly due 
to register_globals change. As this is something which happens at 
compile-time, it should not be possible to change this at run-time.

I don't see this as something which should be changed. Definitely not 
before 5.0 but I'm not sure it's that critical also to change afterwards 
although it might be possible.

We discussed this issue with Jevon Wright (private emails)
and in the end of the day agreed that most simple yet powerful
solution is "superglobals", which would work like $_GET,$_POST
etc.
        $a=array('x'=>1);
        superglobal $a;
        function f() {
                echo $a['x'];
        }
with combination of naming convention to express the constant
nature of the data for example:
        $const_a=...;
        superglobal $const_a;
or
        $MY_PARAMETERS=....;
        superglobal $MY_PARAMETERS;
HTH.
