Answer 1

你忘了发$db在mysqli_query($db, <your request>)

Answer 2

第一个参数你已经创建了一个库MySQLi对象$db这里：

$db = new mysqli($db_server, $db_user, $db_pass, $db_name); 

你在这里使用它：

if($db->connect_errno){ 

所以在这里使用它：

$db->query("INSERT into stinfo (ibsn, name, ftname, mtname, sex, birth, religion, nationality, phone, email, bio, address, joined) 
         values ('$data[0], '$data[1]', '$data[2]', '$data[3]','$data[4]', '$data[5]', '$data[6]', '$data[7]', '$data[8]', '$data[9]', '$data[10]', '$data[11]', NOW())");
