PDOStatement::fetchObject()

I asked on #php.pecl how PDOStatement::fetchObject() differs from PDOStatement::fetch(PDO_FETCH_OBJ); Wez said "it's more like PDO_FETCH_CLASS, but you can pass arbitrary parameters to the constructor on each call or even different class names". I think I'll need some good examples to help sort those ones out in the docs. Helly, do you have any examples of where you would use PDOStatement::fetchObject() versus PDOStatement::fetch(PDO_FETCH_CLASS) or PDOStatemet::fetch(PDO_FETCH_OBJ)? I want to really nail the differences down, because I'm afraid that if we don't do a good job in the docs there will be some confusion for end users... Thanks, Dan
