Those people who kept telling me 'just fix the errors' simply don't understand how complex that CAN be:(  I've only worked my way through half a dozen packages and I've 20 or so to go ... all just to bring things 'up to acceptable php code';)

> I have fixed the problems on the package set I use on a number of my sites, but it simply brings me back to your first comment, since fixing the problems is not the same as producing tidy code going to build on. The original code base comes from PHP4 times, but has now been developed into a base 'content' class from which all other 'content' classes are descended. The static functions create generic url, uri and the like, while the 'instantiated' version simply uses the objects own values to provide the variable elements. If I move the static functions into separate classes why is that better than packaging the descended code in the class itself?

"Better" is highly subjective. For me it's better because it follows the DRY and KISS principles. If the URL building is going to be used both statically as well as within the context of an object, that code does not belong within the class which is the type of that object. If we were only talking objects then yes, it would make sense to put that functionality into the base class, but NOT as a static method.

To repeat, this is highly subjective, and I can only base my opinion on my education and experience. There is no "right" way.

The code needs rewriting so that static functions are called statically, and non-static functions are called on an object. Outside of that and a few other simple rules PHP doesn't care how you organise your code.
