Answer 1

You were rightly advised to create an instance of your class then call the method on it but you said

see thats what i don't want .....i want some way to make it work without adding those two lines...by doing something else...just not that...and i can't figure out what i can do.

That something else is Simple! Make your method static

Declaring class properties or methods as static makes them accessible without needing an instantiation of the class.

public static function display()
{
    $w ="its working";
    self::show($w);
}

Then you can just do

some::display();

Fiddle
