This is not a new feature. In your example each class only has a single parent. Multiple Inheritance is when you do something like: class C extends A,B { ... } Doing B extends A followed by C extends B is still single inheritance. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
