note 124839 added to class.sessionhandlerinterface

If you want to use type declarations in your own session handling class, don't "implements" the SessionHandlerInterface, SessionIdInterface, or SessinUpdateTimestampInterface, otherwise you will get a fatal error saying that declaration of the class method must be compatible with the interface method. a bad example <?php class SessionWuXianchengHandler implements SessionHandlerInterface { public function open(string $sessionPath, string $sessionName) : bool { } ...... } ?> a good example <?php class SessionWuXianchengHandler { public function open(string $sessionPath, string $sessionName) : bool { } ...... } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 175.155.222.41) ---- Manual Page -- http://php.net/manual/en/class.sessionhandlerinterface.php Edit -- https://master.php.net/note/edit/124839 Del: integrated -- https://master.php.net/note/delete/124839/integrated Del: useless -- https://master.php.net/note/delete/124839/useless Del: bad code -- https://master.php.net/note/delete/124839/bad+code Del: spam -- https://master.php.net/note/delete/124839/spam Del: non-english -- https://master.php.net/note/delete/124839/non-english Del: in docs -- https://master.php.net/note/delete/124839/in+docs Del: other reasons-- https://master.php.net/note/delete/124839 Reject -- https://master.php.net/note/reject/124839 Search -- https://master.php.net/manage/user-notes.php
