I have to agree with passing them as opposed to accessing them from inside the function
Clean
$a = "whatever";
function foo($a){
echo $a;
}
Ugly
$a = "whatever";
function foo(){
global $a;
echo $a;
}
Unless the variables in question are for all intents and purposes constant (
real constants can't be arrays ), ie for example configuration vars, I would
avoid making them global.
Having that said, it's your code......
