I went ahead and expanded on kailashbadu's function. This recursive function will also print
out the datatypes of the defined variables and encode all strings with htmlentities(), so that
strings with html inside won't render in the browser. It also returns an Object's
Classname, and its Property names, visiblities, and values. its roughly a mix of var_dump() and a
Print_r() with <pre> tags inserted
