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 ?

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($v1) ; // don't call the dtor
unset($v2) ; // call the dtor

this is also not the full truth try this and it works
what are the circumstances that is causing this problem then, yes I do have
distributed references over my script and there are clearly references still
set, however after running the snipped script I can not see what I do
special in my script causing the problem. I even tried with public and
private static in other objects. it works. however the manual indicates the
refernce counter has to be 0.



abstract class a {
public function __construct(){
echo "constructing....
";
}
public function __destruct(){
echo "destructing....
";
}
}

class b extends a{

}

$c = new b();

$d = $c ; // works
$f[] = $c ; // works

class e {
private $m;

public function setM( $m ){
$this->m = $m;
}
}

$o = new e();
$o->setM( $c ); // works


unset( $c );
