        foreach ($divisi as $row){
            $i = $this->M_model->db_realisasi_divisi($row['divisi_kode']);
            $win = $this->M_model->db_win_win($row['divisi_kode'],'win'); // how to push ?
            $data[] = array(
                'divisi' => $row['kode'], // 01,02

value object 
{
 "status": "win",
 "total": "1"
}

I have a data object that I want to insert into [‘data’] How to do it

Answer

I assume $i is array of arrays, so do array_push($i, $win) (or $i[] = $win)

    public function detail_get() {
        $divisi = $this->M_model->db_tbl_divisi();
        $data = [];
        foreach ($divisi as $row){
            $i = $this->M_model->db_realisasi_divisi($row['divisi_kode']);
            $i[] = $this->M_model->db_win_win($row['divisi_kode'], 'win');

            $data[] = [
                'divisi' => $row['kode'], // 01,02
                'data' => $i,
            ];
        }

        $response = $this->set_response($data,200);
    }
