RE: [PHP] Re: Design for Large OO poject

Errm. You are mistaken. In PHP you can do: class DB{} class Member extends DB() class News extends Member{} This is not multiple inheritance. This is single inheritance. Multiple inheritance is when you create a class by 'extending' multiple classes at one time. You cannot do this in PHP, if you could it would be something like: class News extends A, B {} > -----Original Message----- > From: Julio Nobrega Trabalhando > [mailto:inerteARROBAhotmail.com@pb1.pair.com] > Sent: 08 November 2001 17:27 > To: php-general@lists.php.net > Subject: [PHP] Re: Design for Large OO poject > > > If I am not mistaken, the correct name for your wrong approach (at least > in PHP) is multiple inheritance. > > PHP doesn't support multiple inheritance, only one level. > > So you do can extend one class but not extend the second one from the > first. > > Ie: > > > class DB{} > > Works. > > > class Member extends DB() > > Works. > > > class News extends Member{} > > Doesn't work.
