Yep - but shouldn't object destruction be forced before the memory
manager cleans it up. The example could rather be put as:
<?php
class InstanceContainer {
public $value;
function __construct() {
$this->value = new GenericObject($this);
}
function __destruct() {
print "Called\n";
}
}
class GenericObject {
public $internal;
function __construct($instance) {
$this->internal = $instance;
}
}
$o = new InstanceContainer();
?>
As you can predict, __destruct() won't be called. Shouldn't objects be
unmercifully cleaned up before we rely on the memory manager to burn the leftovers?
