Bug description:request for interface hashCode (Identifiable)
Description:
------------
i, i hope to see something like this in future php releases
interface Identifiable
{
public function /*string*/ hashCode();
}
class Test implements Identifiable
{
public function hashCode(){return spl_object_hash($this);}
}
method hashCode() should be called in these contexts:
$myarr[new Test()] = "test";
$myarrobj->{new Test()} = "test";
and manually inside:
function method(Identifiable $instance){};
the hash should be obtained by calling
$obj->hashCode() if it is Identifiable or
$obj->scalarValue() if it implements ScalarAccess
$obj->__toString() if it has method __toString
or, finally throw an error
what do you think about this?
thank you
