Describe how to set up environment-specific configurations in FuelPHP.

To set up environment-specific configurations in FuelPHP, you can create configuration files tailored to each environment—such as development, staging, and production. Here’s how to do it step by step, along with examples:

Step 1: Create Environment-Specific Configuration Files

In your FuelPHP project, navigate to the fuel/app/config/ directory. Here, you will create specific configuration files for different environments. For example:

For Development: Create config.local.php.
For Production: Create config.production.php.

Example: config.local.php

Example

<?php

return [
    'db' => [
        'driver'   => 'mysql',
        'host'     => 'localhost',
        'database' => 'my_local_db',
        'username' => 'root',
        'password' => '',
        'persistent' => false,
    ],
    'debug' => true,
    'cache' => [
        'enabled' => false,
    ],
];

Example: config.production.php

Example

<?php

return [
    'db' => [
        'driver'   => 'mysql',
        'host'     => 'production-db-host',
        'database' => 'my_production_db',
        'username' => 'prod_user',
        'password' => 'secure_password',
        'persistent' => true,
    ],
    'debug' => false,
    'cache' => [
        'enabled' => true,
    ],
];

Step 2: Load the Appropriate Configuration Based on the Environment

In FuelPHP, you typically have a main configuration file that determines the environment your application is running in. This can be done in fuel/app/config/development.php or fuel/app/config/production.php, depending on your setup.

Example: Loading the Configuration in fuel/app/config/development.php

Example

<?php

// Load the environment-specific configuration
$env_config = require APPPATH . 'config/config.local.php';

// Set up the main configuration array
return array_merge(
    [
        // Common configuration settings
        'app_name' => 'My Application',
        'base_url' => 'http://localhost/myapp/',
    ],
    $env_config
);

Example: Loading the Configuration in fuel/app/config/production.php

Example

<?php
<?php

// Load the environment-specific configuration
$env_config = require APPPATH . 'config/config.production.php';

// Set up the main configuration array
return array_merge(
    [
        // Common configuration settings
        'app_name' => 'My Application',
        'base_url' => 'https://www.myapp.com/',
    ],
    $env_config
);
?>

Step 3: Accessing the Configuration in Your Application

Once you have set up your configuration files and loaded them based on the environment, you can easily access these configurations throughout your application using the Config class.

Example: Accessing Configuration Values

Example

<?php
// Example controller method
public function action_index()
{
    $db_config = Config::get('db');
    $app_name = Config::get('app_name');
    
    // Use the configuration values as needed
    echo "Welcome to " . $app_name;
    echo "Connecting to database: " . $db_config['database'];
}
?>
