Development mode for personal IP address

Hello everyone! Sorry for my bad English, but I try to write my question.
Tell me please, How I can set (or switch on) CI_ENVIRONMENT to DEVELOPMENT mode for my personal IP address?
As example... I have a working web project and I have a bug on any page and I want to switch on development mode, BUT! If I will change .env file and will set development mode this parameter will be set for all clients on my web site. How I can set something:

if($_SERVER['REMOTE_ADDR'] == '12.34.56.78') {
env(' CI_ENVIRONMENT', 'development')
}
I will believe would your understood my question. Thank's!

Hi, Just replace the following code in file app\Config\Boot\production.php.

Code:

<?php

    $yourStaticIP = '::1';
    if(\Config\Services::request()->getIPAddress() == $yourStaticIP){

        error_reporting(-1);
        ini_set('display_errors', '1');

        defined('SHOW_DEBUG_BACKTRACE') || define('SHOW_DEBUG_BACKTRACE', true);

        defined('CI_DEBUG') || define('CI_DEBUG', true);
   
    }
/*
|--------------------------------------------------------------------------
| ERROR DISPLAY
|--------------------------------------------------------------------------
| Don't show ANY in production environments. Instead, let the system catch
| it and display a generic error message.
*/
ini_set('display_errors', '0');
error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT & ~E_USER_NOTICE & ~E_USER_DEPRECATED);

/*
|--------------------------------------------------------------------------
| DEBUG MODE
|--------------------------------------------------------------------------
| Debug mode is an experimental flag that can allow changes throughout
| the system. It's not widely used currently, and may not survive
| release of the framework.
*/
defined('CI_DEBUG') || define('CI_DEBUG', false);

Note this:
1. Enter your IP in section

Code:

$yourStaticIP = '::1';

.
2. Your IP is dynamic so your IP changes when you turn off the modem. In this case, replace it again.

Enjoy!

Awesome!!!!! Very big thank you!!!!!
