From: netadmin@isp.pl Operating system: Red Hat 7.1 PHP version: 4.2.1 PHP Bug Type: Class/Object related Bug description: Object in object (object->reference object) <? class A { var $var_a; function A() { $this->set_a("old"); } function set_a($a) { $this->var_a=$a; } } class B { var $obj_a; function B() { $this->obj_a=new A; } } $my=new B; var_dump($my); $my->obj_a->set_a("new"); var_dump($my); ?> I create new object from class B ($my) variable $obj_a in object $my IS OBJECT from class A. var_dump($my) return object(b)(1) { ["obj_a"]=> object(a)(1) { ["var_a"]=> string(3) "old" } } It's ok. After that I call a method from class A $my->obj_a->set_a("new"); This method change variable $var_a, but after that variable $obj_a IS REFERENCE to object A var_dump($my) return : object(b)(1) { ["obj_a"]=> &object(a)(1) { ["var_a"]=> string(3) "new" } } $obj_a was object, but now $obj_a is reference to object. -- Edit bug report at http://bugs.php.net/?id=17697&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17697&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17697&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17697&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17697&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17697&r=support Expected behavior: http://bugs.php.net/fix.php?id=17697&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17697&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17697&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17697&r=globals
