note 69036 added to language.oop5.decon

Note that if a class contains another class, the contained class's destructor will be triggered after the destructor of the containing class. <?php class contained { protected $parent; public function __construct(&$p) { # $this->parent=&$p; } public function __destruct() { /* unset $this->parent */ print 'contained '; } } class containing { protected $contained; public function __construct() { $this->contained=new contained($this); } public function __destruct() { // unset($this->contained); print 'containing '; } } new containing(); ?> Will output containing contained After uncommenting the // comment, the output will change to contained containing Adding a reference from the contained class to the containing one (the # comment) will not change that, but beware, because it can cause random errors in other destructors in the parts of the script which seem unrelated!
