global variables are evil ;)
no, serious, it would be hard to track down
if statements outside of a function
(maybe in a totaly different file)
could affect the scope of variables inside
a function
either stay with global declarations or
make use of the special $GLOABLS array
or even better: try to design your code
so that it doesn't rely on globals at all
(the global declaration for functions
was invented for a reason)
some keywords: side effects, reentrancy,
thread safety (not a php issue yet),
obfuscation ...

Using "global" is very unfriendly (you have many of them and have to
declare them everytime and everywhere).
You change something and a mess is rising.
I have this idea:
<?
global $foo;
$foo="hello";
function a() {
echo($foo);
}
?>
Today "global" located in the root do nothing. By my idea it should be
"an absolute global" like $GLOBALS.
Then you will be able to use this variable everywhere without defining
it by global everytime.
