Stuart, u are right, the refcount in php 5 doesn't matter, where something
left behind in my memory from earlier days, However i do have the effect
that unsetting an object does NOT call __dectruct() ! but when the script
ends it is called. this can be easily tested by putting a echo in destruct.
I dont agree, and as u see in my snipped code it works fine.
in an abstract class u can define an implementation to define some basic
things a overwriting function in an extending class has to take care of as
well.
this includes specialy magic functions.
thats what they are made for. may be you
see http://cn.php.net/manual/en/language.oop5.abstract.php
PHP 5 introduces abstract classes and methods. It is not allowed to
create an instance of a class that has been defined as abstract. Any
class that contains at least one abstract method must also be
abstract. Methods defined as abstract sim

the constructor is inherited, the destructor not !!

Never calls the dtor. The dtor will be called only when the reference
count reaches 0.
class c { function __destruct() { echo 'dying !' ; } }
$v1 = new c ;
$v2 = $v1 ;
unset($v1) ; // don't call the dtor
unset

That's not entirely correct. PHP uses reference counting, so if
unsetting a variable did not caus
unset($obj) always calls the __destruct() function of the class.
in your case clearly you are missing something else. Probably
unset($anobject) is not being called at all ?
