Array to string conversion

<input type="text" name="companionship[]">
... and so forth.

         $query= $this->db->insert_batch('monthly_statistics', $columns);
 }
    

How can I solve this problem?

after a few hours of pondering, I already fix the errors and now it working fine

here is the code

public function mymethod()
    {



        $companionship_id = $this->input->post('companionship_id[]');
        $zone_id = $this->input->post('zone_id[]');
        $district_id = $this->input->post('district_id[]');
        $area_id = $this->input->post('area_id[]');
        $baptism = $this->input->post('baptism[]');
        $confirm = $this->input->post('confirm[]');
        $ibd = $this->input->post('ibd[]');
        $iasm = $this->input->post('iasm[]');
        $ni = $this->input->post('ni[]');
        $ph = $this->input->post('ph[]');
        $wh = $this->input->post('wh[]');

        $value = array();
        for($i=0; $i<count($companionship_id); $i++)
        {
            $value[$i] = array(
                'companionship_id'  =>      $companionship_id[$i],
                'zone_id'           =>      $zone_id[$i],
                'district_id'       =>      $district_id[$i],
                'area_id'           =>      $area_id[$i],
                'baptism'           =>      $baptism[$i],
                'confirm'           =>      $confirm[$i],
                'ibd'               =>      $ibd[$i],
                'iasm'              =>      $iasm[$i],
                'ni'                =>      $ni[$i],
                'ph'                =>      $ph[$i],
                'wh'                =>      $wh[$i]

            );
        }

        $this->db->insert_batch('monthly_statistics',$value);


        $this->session->set_flashdata("success",alert("alert-success","Successfully Inserted"));
        redirect(base_url('to_url'));
        exit();
    }
