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.
