note 44203 added to language.references

While trying to do object references with the special $this variable I found that this will not work: class foo { function bar() { ... $this =& $some_other_foo_obj; } } If you want to emulate this functionality you must iterate through the vars of the class and assign references like this: $vars = get_class_vars('foo'); foreach (array_keys($vars) as $field) { $this->$field =& $some_other_foo_obj->$field; } Now if you modify values within $this they will be modified within $some_other_foo_obj and vice versa. Hope that helps some people! p.s. developer at sirspot dot com's note about object references doesn't seem correct to me. $temp =& $object; $object =& $temp->getNext(); Does the same exact thing as: $object =& $object->getNext(); when you refernce $temp to $object all it does is make $temp an alias to the same memory as $object, so doing $temp->getNext(); and $object->getNext(); are calling the same function on the same object. Try it out if you don't believe me. ---- Manual Page -- http://www.php.net/manual/en/language.references.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+44203 Delete -- http://master.php.net/manage/user-notes.php?action=delete+44203&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+44203&report=yes Search -- http://master.php.net/manage/user-notes.php
