My question is actually regarding the line "$myref = &$this;". The author states that this is a reference to the class/object itself. Isn't this like saying outside the class "$myref =& new test;"? What would be the point of referring to itself inside the class in this manner? Thanks for your help in advance!

The exact class that the author wrote isn't too useful, although it makes its point well. However, a reference to $this inside a class can be useful, for example, if you were using the observer pattern.
