<?php
abstract class TAbstractParam {
protected $FValue = null;
public abstract function getType(); //getType
public function Dump() {
return "TYPE=" . $this->getType() . " VALUE=" . $this->FValue;
}
}
interface IParam {
public function getType(); //getType again.
}
class TStringParam extends TAbstractParam implements IParam {
public function getType() {return 'VARCHAR'; } //another getType, the fatal
error goes here.
}
see this example, please...

there are other non-abstract methods inside the abstract class to provide some
base behaviors for its children claclasses, which i omitted in this example.
and those non-abstract methods may call the abstract methods. and an abstract
class should not be defdefined as an instance cclass for an interface cuz an
non-abstract one should, so why ambiguity?

Expected behaviour, your code causes ambiguity.

I have adapted those code(see it below) into delphi(object pascal, on
Delphi2010), however, nothing wrong at all. so i think it should be a wrong oop
logic in php5(5.2 included also, since i've tested then...)
Type
TAbstractParam = Class(TInterfacedObject)
Procedure getType(); Virtual; Abstract;
End;
IParam = Interface
Procedure getType();
End;
TPrimativeParam = Class(TAbstractParam, IParam)
Procedure getType();
End;
//Other code omitted...
