Copying objects with <?php public function copy() { $serialized_contents = serialize($this); return unserialize($serialized_contents); } ?> is a pretty dangerous thing. What if your objects hold references to very large shared objects? They all get copied as well. Serializing objects may break database connections and references. What you probably want to do is implement a proper __clone() method for each of your classes so that each object in your tree gets to decide what subobjects need to be copied and which ones should better remain untouched. regards felix ---- Server IP: 212.124.37.9 Probable Submitter: 217.27.204.139 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.cloning.php Edit -- https://master.php.net/note/edit/69832 Del: integrated -- https://master.php.net/note/delete/69832/integrated Del: useless -- https://master.php.net/note/delete/69832/useless Del: bad code -- https://master.php.net/note/delete/69832/bad+code Del: spam -- https://master.php.net/note/delete/69832/spam Del: non-english -- https://master.php.net/note/delete/69832/non-english Del: in docs -- https://master.php.net/note/delete/69832/in+docs Del: other reasons-- https://master.php.net/note/delete/69832 Reject -- https://master.php.net/note/reject/69832 Search -- https://master.php.net/manage/user-notes.php
