variable scope

[jsk137]

How do I make a variable available outside its current scope? I have a variable called $balance and I need to use it outside its current scope.

I have tried to define a constant, but I only get '$balance' as its value. I need to assign the value of the variable $balance to the constant I am defining.

Thanks,
Jeff

By scope, I assume it is in a function/class. You could define the variable initally outside the function/class, and use the global statement at the start of the function like this:

$balance = "";

function foo($arg) {
  global $balance;
  $balance = $arg;
  return $arg;
}

$test = foo("test");
echo $test . $balance;
