So I have two classes like this:

class foo {
    /* code here */
}
$foo = new foo();
class bar {
    global $foo;
    public function bar () {
        echo $foo->something();
    }
}

I want to access the methods of foo inside all methods bar, without declaring it in each method inside bar, like this:

class bar {
    public function bar () {
        global $foo;
        echo $foo->something();
    }
    public function barMethod () {
        global $foo;
        echo $foo->somethingElse();
    }
    /* etc */
}

I don't want to extend it, either. I tried using the var keyword, but it didn't seem to work. What do I do in order to access the other class "foo" inside all methods of bar?
