A PHP Error was encountered

is there space above your php tag in the user controller?if yes delete the unwanted space,also just comment the print_r($reg_data); — Sanjuktha
Don't depend on user input. Always make dummy proof code. Best way should be to have more input fields i.e. $f_name, $m_name, $l_name and in controller check those if not empty before using them. — Tpojka

use this line

'lastname'=>$fullnameSplit[2],

as

'lastname'=>isset($fullnameSplit[2]) ? $fullnameSplit[2] : '',

The error undefined offet:2 means the array $fullnameSplit with key [2] does not exists or is not set. So you need to check condition isset() to avoid that message
