question about inheritance

[bough]

Hello,

I have a query which i was wondering if anybody can answer.

I know that you are unable to have mulitple inheritance in OO PHP, but i wondering if the fowllowing example would be possible.

if I had a classs "ERROR" which was inherited by another class "DBCLASS", then had a 3rd class "FORUM" which in-turn inherited the "DBCLASS", would the "FORUM" class be able to access the methods and functions from the ERROR class or would this be classed as mulitple inheritance?

sorry if this is a confusing post,

many thanks
Ian

Multiple inheritance is one class inheriting from 2 or more parent classes. What you have described is single inheritance, albeit with parent and grandparent classes.

// Multiple inheritance
class c extends a, b{}
// Single
class a{}
class b extends a{}
class c extends b {}
