Workaround for PHP5 bug.

PHP5 has a bug in handling boolean return values for SessionHandlerInterface methods, it expects 0 or -1 instead of true or false. See https://wiki.php.net/rfc/session.user.return-value.

PHP7 and HHVM are not affected.

Todo: When we drop support for Zend PHP 5, this can be removed.

Returns: bool|int

◆ setEnableFlags()

MediaWiki\Session\PHPSessionHandler::setEnableFlags ( $PHPSessionHandling )
