note 77826 added to function.unserialize

Ignore all the advice to implement __autoload-ers or magical handlers, to solve problems when retrieving class instances from sessions. It leads to terrible debugging nightmares. After fussing with all sorts of such solutions and getting nowhere, I've found a very simple solution that works correctly and explicitly: $_SESSION['myInstance'] = serialize($myInstance); .... $myInstance_s = @$SESSION['myInstance'] if (!is_null($myInstance_s)) { $myInstance = unserialize($myInstance_s); } In other words, serialize the thing as a string, and put it in the session in this state - you regain control of the unserialization process and can code to handle exception cases rather than praying php's black magic does the right thing (and being sorely disappointed when it doesn't). ---- Server IP: 209.41.74.194 Probable Submitter: 38.117.159.162 ---- Manual Page -- http://www.php.net/manual/en/function.unserialize.php Edit -- https://master.php.net/note/edit/77826 Del: integrated -- https://master.php.net/note/delete/77826/integrated Del: useless -- https://master.php.net/note/delete/77826/useless Del: bad code -- https://master.php.net/note/delete/77826/bad+code Del: spam -- https://master.php.net/note/delete/77826/spam Del: non-english -- https://master.php.net/note/delete/77826/non-english Del: in docs -- https://master.php.net/note/delete/77826/in+docs Del: other reasons-- https://master.php.net/note/delete/77826 Reject -- https://master.php.net/note/reject/77826 Search -- https://master.php.net/manage/user-notes.php
