error Undefined offset while using explode

Question

     $a = explode(",",$data['ids'][$i]);   
  $dbtvalues = array();
                for($j=0;$j< count($a);$j++)
                {   
                    $dbtvalues['serial_no'] =$a[$j];
                    if($data['modelno'] !="select")

                    {
                    $dbtvalues['model_no'] = $data['modelno'][$j];
                    }

                    $dbtvalues['indent_detail_id1'] = (int)$last_id ;
                    $data['indent_req_detail_id'][$i];

                    $this->outpatient_model->insert_row('tra_indent_issue_detail',$dbtvalues);

                }

$a need to explode and insert into db if array has 5 values 5 rows must be inserted into table.

Index is not exists. that why warning occurs

$a=array();
if(!empty($data['ids'][$i]))
$a = explode(",",$data['ids'][$i]);

Put above if condition it's working when index is not empty.
