using unset() on global variable

[junebug]

i am trying to unset a variable in a function. it looks basically like this:

$var = "hello world";

function remove()
{
global $var;
unset($var);
}

remove();
print $var;

okay, now what i want is for the variable to be unset on a global scope, not just the local scope. can i do this from a function?

much thanks in advance.

function foo() {
unset($GLOBALS['bar']);
}

$bar = "something";
foo();

Hope this helps;
