note 130253 added to sessionupdatetimestamphandlerinterface.updatetimestamp

This is largely speculation based on what I can see in php-src - it appears that the $data argument is included for two reasons: 1. If you subclass SessionHandler and implement SessionUpdateTimestampHandlerInterface, your updateTimestamp() method may be called - but you can't call parent::updateTimestamp() because that method isn't implemented on SessionHandler. So instead you must call parent::write() which means you need the data to avoid overriding it with a blank session. 2. This simplifies the source code for PHP, since depending on whether there _is_ data and whether lazy session.lazy_write is enabled, either this method or write() will be called when the session is closed. Having the same arguments means only the name of the method being called has to change, not the arguments. The second reason feels a bit flakey so I don't trust my own reasoning there. But the first reason seems sound. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 14.1.35.58) ---- Manual Page -- https://php.net/manual/en/sessionupdatetimestamphandlerinterface.updatetimestamp.php Edit -- https://main.php.net/note/edit/130253 Del: integrated -- https://main.php.net/note/delete/130253/integrated Del: useless -- https://main.php.net/note/delete/130253/useless Del: bad code -- https://main.php.net/note/delete/130253/bad+code Del: spam -- https://main.php.net/note/delete/130253/spam Del: non-english -- https://main.php.net/note/delete/130253/non-english Del: in docs -- https://main.php.net/note/delete/130253/in+docs Del: other reasons-- https://main.php.net/note/delete/130253 Reject -- https://main.php.net/note/reject/130253 Search -- https://main.php.net/manage/user-notes.php
