Answer 1

If you did a var_dump on your login variable you will see that it is an array not an object so you can't deal with it like an object.
so go to your model and modify the following:
$customer = $result->row_array();
to be:
$customer['result'] = $result->row_array();
then in line 46 use it as:
$login['result']->last_name;
Why this is happening:
because as you defined $customer as an object at first. you also redefined it later in your model as an array by using $customer['something'] pattern of assignation.
So you can't have it your way, it's either an array or an object.

Answer 2

//You used this code because row_array return array not object
`$`login["result"] = `$`this->Customer_model->login(`$`email, `$`password, `$`remember);
echo $login['result']["last_name"];
