note 105005 added to class.arrayobject

A gotcha that is indeed mentioned in the manual, but isn't readily obvious and just cost me half an hour: Objects implementing the Serializable interface do NOT get __sleep and __wakeup called; instead, they use serialize and unserialize methods, respectively (why, I don't know, but whatever - I'm sure there's a reason). Hence, I was trying to serialize a database resultset in an object extending ArrayObject, and needed to fix some stuff regarding database resources on serialize. Took me a while to figure out __sleep wasn't getting called because ArrayObjects implements Serialize... Presumably the ArrayObject internally implements the serialize/unserialize methods (in a trivial manner), hence the error wasn't apparent immediately (i.e., no fatal error was thrown) and I'd been trying to track why my objects didn't get serialized (they were of course) instead of renaming and fixing the methods. ---- Server IP: 69.147.83.197 Probable Submitter: 78.27.38.24 ---- Manual Page -- http://www.php.net/manual/en/class.arrayobject.php Edit -- https://master.php.net/note/edit/105005 Del: integrated -- https://master.php.net/note/delete/105005/integrated Del: useless -- https://master.php.net/note/delete/105005/useless Del: bad code -- https://master.php.net/note/delete/105005/bad+code Del: spam -- https://master.php.net/note/delete/105005/spam Del: non-english -- https://master.php.net/note/delete/105005/non-english Del: in docs -- https://master.php.net/note/delete/105005/in+docs Del: other reasons-- https://master.php.net/note/delete/105005 Reject -- https://master.php.net/note/reject/105005 Search -- https://master.php.net/manage/user-notes.php
