In reply to tim dot ward at stivesdirect dot com: I had a need to to do a very similar thing. I wrote a class that will be used to create an object which can serialize itself into a cookie and be used to recover itself from the cookie later. To do the recovery you must use the Scope Resolution Operator (::) to call a function as a class function (vs. and object function). The recovery is very simple to initiate because there is only one line of code to call (e.g. $the_object = the_class::the_function(); ) But the function you call must do a ton of stuff, and call a few other functions within the class. This is where the problem lies. I would like to thank <brooke at jump dot net>, <pollita at php dot net>, and <MagicalTux at FF.ST> (from http://php.net/manual/en/function.get-class.php) for leading me to the solution. <?php class foo { function get_object_from_cookie(...) { ... return unserialize($decrypted_cookie_data); } function recover_from_cookie() { ...prepare to recover... // The next line is the tricky part. $o = call_user_func(array(__CLASS__, 'get_object_from_cookie'), $encryption_secret, $cookie_name); $temp = $o->get_stuff(); $o->other_stuff = $o->do_calculate($temp); $o->do_complicated_things(); return $o; } } $bar = foo::recover_from_cookie(); ... ?> I hope that saves someone an hour. It sure would have saved me one. ---- Manual Page -- http://www.php.net/manual/en/keyword.paamayim-nekudotayim.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52685 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52685&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52685&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52685&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52685&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52685&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52685&report=yes Search -- http://master.php.net/manage/user-notes.php
