Answer 1

Check this code

"400", "message" =>$message ]); exit; } else { $message['success'] = "Successful"; // success messsage if needed $data = null; // whatever data you need to pass in success resposne - either fetch from Database or hardcoded // validated flow echo json_encode([ "status" => "200", "message" =>$message, "data" => $data ]); } ?>

==================================

Success resposne:
{"status":"200","message":{"success":"Successful"},"data":null}

 Failed response:
 {"status":"400","message":{"error_email":"Email address required.","error_mobile":"Mobile number required."}}

If email exists and mobile number empty then 
Failed response:
{"status":"400","message":{"error_mobile":"Mobile number required."}}
