\BHB::$reg->oSet(), oGet(), oUnset(), oExists()
allow us to create a var and add a message and have it available in the rest of our applications.
Caution: If in the App that are writing you use a redirect, \BHB::reg() will lost the var.
In this case you need to use \BHB::$msg->oSet() that store the var and its value in $_SESSION.
<?php \BHB::$msg->oSet($offset, $value); \BHB::$msg->oGet($offset); \BHB::$msg->oExists($offset); \BHB::$msg->oUnset($offset);
end.
