I don't consider them as 'bad' per se, but as Masi indicated:
* there are many hooks (if a lot of them are used it will most likely 
cost performance)
* they expose the inner workings of a function
The last point has both disadvantages (hooks will be broken if the 
implementation of a function/method changes) and advantages (the 
functionality of a method/function can be modified without changing 
source code).

I can only see interfaces as a way to keep APIs constant over a period 
of time and as a way to define APIs for objects which might have variety 
in implementations. Both can of course be achieved by other means.
Maybe I don't understand PHP interfaces very well and maybe OO experts 
are very enthusiastic about them...
