function check($class_data,$subject)
{
foreach($class_data as $key => $value)
{
$this->db->select('s_id');
$this->db->from('table1');
$this->db->where('type',2);
$this->db->where('subject',$subject);
$this->db->where('status',1);
$condition= array(
'class' => $key,
'stream_index' => $value
);
$this->db->where($condition);

I think this will help you..
function check($class_data,$subject){
$class_teacher_count = array();
foreach($class_data as $key => $value){
$this->db->select('s_id');
$this->db->from('table1');
$this->db->where('type',2);
$this->db->where('subject',$subject);
$this->db->where('status',1);
$this->db->where('class', $key);
$this->db->where('stream_index',$value);
$query = $this->db->get();
$rows = $query->result();
$count = count($rows);
$class_teacher_count[$key] = $count;
}
return $class_teacher_count;
}

function check($class_data,$subject){
foreach($class_data as $key => $value){
$this->db->select('s_id');
$conditions = array(
'type' => 2,
'subject' => $subject,
'status' => 1,
'class' => $key,
'stream_index' => $value
);
$teacher_count[$key] = $this->db->get_where('table1',$conditions)->num_rows();
}
return $teacher_count;
}
