Question

I have an array

$user = array([0]=>1 [1]=>2 [2]=>3)

which contains id’s of certain users.
I need to get the countries of these users from database.

foreach($userid as $user){
    $this->db->select('country');
    $this->db->where('user_id',$user);
    $this->db->from('company');
    $usercountry = $this->db->get();
    $count = $usercountry->row();
    $country = $count->country;
    }

Suppose user1 has country ES, user2 has IN, user3 has US, user4 has UK. then if array contains 1,2,3. Then i need to get the countries ES,IN,US.

Answer 1

This is the way normal query for this kind of array’s

public function get_countries($user)
{
 $query = "select country from company where user_id IN($user)";
 $result = $this->db->query($query);
 if($res->num_rows()>0){
        return $res->result("array");
    }
    return array();
}
