It is not lost in previous PHP versions, and Symfony's HttpFoundation actually relies on this behaviour. php -v PHP 7.0.0-dev (cli) (built: Jul 7 2015 22:52:27) (DEBUG) Copyright (c) 1997-2015 The PHP Group Zend Engine v3.0.0-dev, Copyright (c) 1998-2015 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies Test script: --------------- session_start(); $session = &$_SESSION; $session['test'] = 1; session_regenerate_id(false); $session['test'] = 2; // dumps false, should be true var_dump($session['test'] === $_SESSION['test']); Expected result: ---------------- bool(true) Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70013&edit=1
