Dalam membuat sebuah sistem informasi dibutuhkan skill dan logika yang mumpuni. Setidaknya memahami dalam setiap masalah yang ada seperti dalam aplikasi berbasis web dengan CodeIgniter. Pernahkah anda memiliki hasil tampilan seperti ini:
A PHP Error was encountered

Lalu bagaimana cara mengatasi masalah ini,
Bagaimana cara untuk membedakan CodeIgneter atau CI di locahost dan server atau hosting,
Jika ada masalah seperi di atas, maka lakukan perubahan Config pada Folder Application/config/config.php.
Jika menggunakan localhost, maka cari dan gunakan kode berikut:
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
//$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
Jika menggunakan server atau hosting, maka cari dan gunakan kode berikut:
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
//$config['sess_save_path'] = NULL;
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
Masih banyak masalah lainnya. Seperti
A PHP Error was encountered

Pemecahan masalahnya adalah sebagai berikut:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Main extends CI_Controller
{
function __construct()
{
parent::__construct();
setlocale(LC_TIME, "");
.................................................
ini_set('max_execution_time', 0);
ini_set('memory_limit','2048M');
}
Kode ini ditambahkan pada Controller yang ingin diberikan tambahan waktu upload file
ini_set('max_execution_time', 0);
ini_set('memory_limit','2048M');
Kesalahan lain:

F:\xampp7\htdocs\project\vendor\php-activerecord\php-activerecord\lib\DateTime.php on line

Pemecahan masalah:
ganti file dengan https://github.com/jpfuentes2/php-activerecord/blob/master/lib/DateTime.php
hilangkan implements DateTimeInterface pada baris 36 yaitu:
class DateTime extends \DateTime

In CodeIgniter 3.x if you just upgraded to PHP version 7.x, go to system/libraries/Session/session.php at line 281 and replace or give comment for this line "//":
ini_set('session.name', $params['cookie_name']);
change it with:
ini_set('session.id', $params['cookie_name']);
