Hello guys,
I was thinking of a simple way to change between supported framework environments, so i made this.

Step 1: we need to configure environment via \Config\App at App/Config/App.php file:

PHP Code:

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class App extends BaseConfig
{

    /**
     | You can load different configurations depending on your
     | current environment. Setting the environment also influences
     | things like logging and error reporting.
     |
     | This can be set to anything, but supported usage are:
     |
     |     development
     |     testing
     |     production
     */
    public $environment = 'development'; 


 
Step 2: we should add default supported environments list in system\CodeIgniter.php file:

PHP Code:

<?php namespace CodeIgniter;

class CodeIgniter
{
    protected $environment = [
        'development',
        'testing',
        'production'
    ]; 


Step 3: we have to edit some codes to make it work as expected, search for detectEnvironment() function in system\CodeIgniter.php file:

PHP Code:

    protected function detectEnvironment()
    {
        // Make sure ENVIRONMENT isn't already set by other means.
        if (! defined('ENVIRONMENT'))
        {
            // running under Continuous Integration server?
            if (getenv('CI') !== false)
            {
                define('ENVIRONMENT', 'testing');
            }
            else
            {
                $config = new \Config\App;
                if (! in_array($config->environment, $this->environment))
                {
                    die("The application environment <span style='color:red'>{$config->environment}</span> is not supported, currently supported enviroments are: " . implode(", ",$this->environment) . '.');
                }
                define('ENVIRONMENT', $_SERVER['ENVIRONMENT'] ?? $config->environment);
            }
        }
    } 


Thats all for me, I'm new in php world so I don't know what are the consequences.
