Accessing global variable from a function

[Vitaly Belman]

I'd like to access a global variable from within a function, without
passing it as paramater. How do I do it? e.g

def func
puts i
end

i = 5
func

In PHP, for example, I could use the "global" keyword in the function.

You want to use a global variable, like so:

def func
puts $i
end

$i = 5
func

The "$" tells Ruby it's global.

Yeah... one of the most distracting "features" of PHP *shrugs*.

Global variables start with a "$" so just write

def func
puts $i
end

$i = 5
func
