Re: [PHP-DEV] :: context access (bug?)

[Andi Gutmans]

This is a "feature". We decided to keep it the way it is, and have people 
who really want to code correctly define their static methods as static.
So to fix this you should define Miew() as static and you won't have access 
to the calling scope.

I´ve found the example below which took my attention.

The call to cCat::Miew() assumes the cDog context and
is able to access $this of cDog.
Is this supposed to be a bug or something that was not
expected ?????
It happens to PHP4 to and php5. And looks a bit
strange...
class cCat {
   function Miew(){
     // cCat does not have a member "kind", but cDog
has, and we'll use it
     echo "I am ".$this->kind.", and I say MIEW\n";
     // here things are even stranger: does cCat class
     // support WhoAmI function? guess again...
     $this->WhoAmI();
   }
  }
  class cDog {
   public $kind = "DOG";
   function Bark(){
       // let's make this dog act like a cat:)
       cCat::Miew();
   }
   function WhoAmI(){
     echo "Yes, I'm really ".$this->kind."!";
   }
  }
 $dog = new cDog();
  echo $dog->Bark();
//outputs:
//I am DOG, and I say MIEW
//Yes, I'm really DOG!
