Импортируйте медленную производительность Excel в цикле Foreach и выполняйте фильтрацию

Question

Следующий код выполняется невероятно медленно при выполнении цикла FOREACH, затем выполните фильтрацию с использованием данных из таблицы cabang и вставьте в таблицу с именем part_rak.

. Затем выполняется цикл фильтрации по каждой строке в файле Excel.* на основе цикла comma разделитель

цикл фильтрации

if (explode(",", $rowData[0][14]) > 1) {

                foreach (explode(",", $rowData[0][14]) as $key => $value2) {
                    $data       = array(
                                "rak_part_id"   => $last,
                                "rak_cabang_id" => $this->spareparts_m->get_cabang_id_by_code("B"),
                                "rak_code"      => $value2,
                                "rak_created_at"=> date('Y-m-d H:i:s')
                    );
                    $this->db->insert("part_rak",$data);
                }

            }else{
                foreach (explode("|", $cabang) as $key => $value) {
                    $data       = array(
                                "rak_part_id"   => $last,
                                "rak_cabang_id" => $value,
                                "rak_code"      => $expRak[$key],
                                "rak_created_at"=> date('Y-m-d H:i:s')
                    );
                    $this->db->insert("part_rak",$data);

                }
            }

вот мой метод модели get_cabang_id_by_code

public function get_cabang_id_by_code($cabang_code)
    {
        $q = $this->db->get_where("cabang",array("cabang_code" => $cabang_code));
        return $q->result_array()[0]['cabang_id'];
    }

Буду признателен за любые предложения, которые улучшат производительность моего скрипта.
