codes

Models:

function get_particular($sid){
$this->db->select('*');
$this->db->from('members m');
$this->db->join('subjects s', 'm.sid=s.ssid', 'left');
$this->db->join('class c', 'm.sid=c.csid', 'left');
$this->db->where('m.sid', $sid);
$query = $this->db->get();
return $query->result_array();
}

Controller:

function particular($sid){
$sid=$this->uri->segment(3);
$this->load->model('names');

$this->data["names"]=$this->names_rank->get_particular($sid);
$this->load->view("view/details", $this->data);
}

view:

foreach($names as $name) {

echo $name['sid'].' '. $name['first_name'].' '. $name['surname'].' '.$name['class_name'];
}

Answer 1

What if you remove the loop - Changing your view

From

foreach($names as $name) {

echo $name['sid'].' '. $name['first_name'].' '. $name['surname'].' '.$name['class_name'];
}

To

echo $name['sid'].' '. $name['first_name'].' '. $name['surname'].' '.$name['class_name'];

or if you need the loop, then it should loop for each member and echo name. ie foreach $member echo $names

Answer 2

Details from tables members (first_name and surname) and class (class_name) are shown in view. So remove the left join to subjects table from query. this join is the reason for repeated records if there are more than one record for same member

$this->db->select('*');
$this->db->from('members m');
$this->db->join('class c', 'm.sid=c.csid', 'left');
$this->db->where('m.sid', $sid);
$query = $this->db->get();
return $query->result_array();
