Stumped.

$num = 10;
function multiply()
{
$num = $num * 10;
}
multiply();
echo $num;

This prints "10" to the screen.

$num = $num * 10;
echo $num;

But this prints "0".

Why is that?

good catch.. I made a type-o when posting.

The problem remains, though - if $x * 2 = 0 (where x is not set), then why is the function returning a number instead of 0?

Variable scope. See my response.
