abstract class Css {
    abstract protected function parse($data);
}

abstract class CssElem extends Css {
    a         


        

Answer 1

I recently encountered this Problem as well. For me it helped upgrading from PHP 5.3.8 to PHP 5.3.28.

I don't know exactly when the change happened but in 5.3.28 it is possible to redeclare interface methods in abstract classes and still inherit from them.
