PHP: call child constructor from static method in parent

Question

I want to have a static method in a parent class that creates instances of whatever subclass i call this method on.

An example to make this more clear:

cl         


        

Answer 1

As of php 5.3 you can use the static keyword for this

prints

object(A)#1 (0) {
}
object(B)#2 (0) {
}
object(C)#1 (0) {
}

edit: another (similar) example

prints

t=A
 A::__construct
  type of o=A
t=B
 B::__construct
  type of o=B
t=C
 C::__construct
  type of o=C
