Hi Mike,
Here's the thing.. I declared $page_title = "My Page Title" in a
file called config.php which is included in the index.php page. when I tried
to -> echo $page_title <- Nothing comes out.
If I declared it as global $page_title , then "My Page Title" would
be echoed out.
That I think is the simplest way to explain it.
Cheers,

Not correct.
Variables used in the global scope are global, and appear in the $GLOBALS
array as soon as they come into existence. A global statement is used
within a function merely to declare that you wish to use one of those
variables in that function, where it would otherwise not be available. It's
sort of equivalent to saying "when I use variable $x in this function, I
actually want it to be $GLOBALS['x']" -- or, in PHP terms, $x =
&$GLOBALS['x'].

I'm really not sure what you're getting at here, but I think it may be based
on a misunderstanding. If you could explain exactly what it is you're
trying to do, someone might be able to offer some better help.
Cheers!
