That's not entirely correct. PHP uses reference counting, so if
unsetting a variable did not cause the object to be destructed then
it's highly likely that there is another variable somewhere that is
holding a reference to that object.

Re: unset( $anobject) does not invoce __destruct()

that is correct and that is the problem, and even that is not all !!!

try this


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

class b extends a{

}
$c = new b();
unset( $c );
?>

the constructor is inherited, the destructor not !!

PHP 5.2.9-1 and
PHP 5.3.0 behave the same
