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.
<?php
abstract class a {
public function __construct(){
echo "constructing....<br>";
}
public function __destruct(){
echo "destructing....<br>";
}
}
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 );
?>
