Edit report at https://bugs.php.net/bug.php?id=71187&edit=1 ID: 71187 Updated by: yohgaki@php.net Reported by: akauffman at ne4u dot com Summary: session_regenerate_id(): Failed to create(read) session Status: Assigned Type: Bug Package: Session related Operating System: Ubuntu 14.04 LTS PHP Version: 7.0.1 Assigned To: yohgaki Block user comment: N Private report: N New Comment: When I ported the save handler, I think I made sure it returns string always for successful cases. I'll have a look shortly. @akauffman, could you give info where did you get the memeached module source code? Just making sure to get the same code. Previous Comments: ------------------------------------------------------------------------ [2015-12-21 20:39:29] akauffman at ne4u dot com Description: ------------ There seems to be a type casting problem with custom session handlers (specifically the memcached module) when session_regenerate_id() is called. Perhaps related to a null return value. It looks like it was introduced around 7RC3. Error: PHP message: PHP Catchable fatal error: session_regenerate_id(): Failed to create(read) session ID: user Test script: --------------- Problem: <?php set_ini('session.save_handler','memcached'); set_ini('session.save_path','host1:11211'); session_start(); $_SESSION['value'] = session_id(); session_regenerate_id(); ?> Work around: <?php set_ini('session.save_handler','memcached'); set_ini('session.save_path','host1:11211'); class MemcachedSession extends SessionHandler { public function read($session_id) { return (string)parent::read($session_id); } } $sess = new MemcachedSession(); session_set_save_handler($sess, true); session_start(); $_SESSION['value'] = session_id(); session_regenerate_id(); ?> Expected result: ---------------- Shouldn't have to implement a workaround. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71187&edit=1
