The reason the above-mentioned $ref assignment doesn't work is because of a peculiarity with
the "global" keyword.
global $ref;
Actually makes a new variable $ref which refers to the same item as the external $ref variable.
When you change the $ref value in the function, you are changing *its* reference but not the
external one.
