PHP中的超类和子类

Question

Consider the following PHP class code

class SuperIdea{
.
.
.
static function getById($id){  new SuperIdea(.......); } 
.
.
.
.
}

class SubIdea extends SuperIdea{
}

The problem I face here is that when I call SubIdea::getbyId($t); the object returned is of type SuperIdea but I would like it to be of SubIdea.Is there any way to achieve it without repeating code in SubIdea?

Answer 1

Try replacing new SuperIdea() with new {get_called_class()}();

I've never tested this, but I see no reason why it shouldn't work...
