I have an application built with Codeigniter 3 HMVC.The application was working fine on PHP 5.6 version, But after upgrading my PHP version to 7.1.4 I was not able to log in into my application. After a complete checkup I found that session is not setting at all.
I role back to PHP 5.6 and session was working fine again while switching to PHP 7.1.4 bring the "session not working" issue back.
I tried altering some config value like cookie prefix and cookie save name etc, nothing seems to fix it.
Can anyone please help.
I found that the issue is with some earlier version of Codeigniter 3 and this is a bug already reported in their website.The underlying session bug has been fixed on:
So in the latest version of Codeigniter 3 this issue doesn't happen.
If you are already in a faulty version codeigniter consider replacing system folder with latest version's one. Version 3.1.6 at the time writing this.
In codeigniter 3.1.9 and PHP 7.2 on XAMPP(windows), I checked my application/config/config.php and saw the sess_driver was database:
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = '165_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = "ci_sessions";
So I created the database ci_sessions with:
CREATE TABLE IF NOT EXISTS `ci_sessions` (
`id` varchar(128) NOT NULL,
`ip_address` varchar(45) NOT NULL,
`timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
`data` blob NOT NULL,
KEY `ci_sessions_timestamp` (`timestamp`)
);
And it worked.
