类继承 [英] Class inheritance

问题描述

有没有办法在PHP4中获得多个继承？例如，我有

3个父类，A，B和C类。我希望类X继承所有这3个
类。考虑合并这3个类是不可能的，因为

是Y类，它只继承自A类等。


TIA

Hi,

Are there any ways to get multiple inheritace in PHP4? For example, I have
3 parent class, class A, B, and C. I want class X to inherit all those 3
classes. Consider merging those 3 classes is out of the question, as there
are class Y which only inherits from class A, etc.

TIA
