__destruct() not called ! we shot us in the foot try the script

well I would call this an error in the first view , and some of u where
right! and the stuff with the refernce counter seems to be right as well.

however I can't see a reason for it as 5.x works through refernces. so
unsetting a REFERENCE to the object does not destroy it.

How to destroy the object then?



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

class b extends a{

public function doSomething(){
echo "I'm doing ...but the reference c to the object is unset()
";
}

}

$c = new b();

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

class e {
public static $m;

public static function setM( $m ){
self::$m = $m;
}
}

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

echo "unsetting ...
";
unset( $c );

$d->doSomething();

echo "script ending now ...
";

?>

We would like the solution place in the archives to future visitor benefit.

__destruct is called only when the object is detroyed.
The object is destroyed only when there is no references to it.



error_reporting( E_ALL | E_STRICT );
header( 'Content-Type: text/plain' );

class Foo
{
function __destruct()
{
echo __METHOD__, PHP_EOL;
}
}

$a = new Foo;
$b = $a; # <<<< try the script without this line or commented
unset( $a ); # no destructor called
echo '--', PHP_EOL;
unset( $b ); # destructor called!
