hi i am getting issue of example given in 13CH and 14Ch, i read somewhere that it is related to system configuration but i dint get any clue. i am using wamp2.2E(64bit) on windows-7(64bit).

in chapter 14 issues are following:-
Strict standards: Non-static method DataObject::connect() should not be called statically in C:\wamp\www\test\book_club\Member.class.php on line 71

Strict standards: Non-static method DataObject::disconnect() should not be called statically in C:\wamp\www\test\book_club\Member.class.php on line 79

I had the same problem. In order to fix it I changed the connect() and disconnect() methods to

protected static function connect() and
protected static function disconnect()

Since I'm brand new in PHP I don't know if this would have any unwanted side effects for the rest of the program.
