Bismillah ....
Kebetulan development internal masih menggunakan PHP 5, dan beberapa fungsi ada yang gak berjalan, langkah terbaiknya dengan memanfaatkan helper dan disimpan dalam function.
Untuk aturan pembuatan helper silahkan liat dokumentasinya, untuk function yang gw buat di Codeigniter 2 dan 3, biasanya ditulis dengan namaHelper_helper.php yang disimpan di folder helpers.
Lanjut ke scriptnya beserta manfaat singkatnya, untuk sumber code nyah gw sertakan juga ya sudah gw sertakan juga ya.
