Controllor
$studentID = []; // Multiple Student ids
$comments = [];
$this->data['set'] = $id; //class id
$this->data['students'] = $this->student_m->get_order_by_student(array('classesID' => $id, 'schoolyearID' => $schoolyearID));
foreach($this->data['students'] as $key => $val){
$studentID[] = $val->studentID; //
}
foreach ($studentID as $student) {
$comments[] = $this->sattendance_m->get_comment($id,$student);
}
$this->data['comments']= $comments;
print_r($comments);
Model
function get_comment($id,$student) {
$this->db->select('attendanceID,comment');
$this->db->where('classesID', $id);
$this->db->where_in('studentID', $student);
$this->db->order_by($this->_primary_key,"desc");
$this->db->limit(1);
$this->db->from($this->_table_name);
$query=$this->db->get();
return $query->result();
}
View
<?php
if(count($comments)) {
foreach ($comments as $key => $row) {
echo $row->comment;
}
}?>

Answer 1

As you can see output of print_r you have multiple comments per student. So you need to do inner loop again
if(count($comments))
{
foreach ($comments as $key => $row) {
foreach ($row as $value) {
echo $value->comment;
}
}
}

Answer 2

this should be
<?php
$i=0;
if($comments)
{
foreach ($comments as $key => $row) {
echo $key[$i++]->row
}
}else{
echo "null";
}
?>
