How do I handle complex logic in Laravel configuration files without using closures

1. Move the complex logic to a separate class or function:
- Create a static method in a class that encapsulates the complex logic[1][2].
- Define a regular function that returns the desired configuration value[1].
- In your configuration file, reference the class and method or the function instead of using a Closure[1][2].

Example:

php
   // config/mypackage.php
   return [
       'option' => [MyClass::class, 'getOption'],
   ];
   

2. Use environment variables to store complex configuration values:
- Store complex configuration values in environment variables (e.g., `.env` file)[3].
- In your configuration files, use the `env()` function to retrieve the values from the environment variables[3].

Example:

php
   // config/database.php
   return [
       'connections' => [
           'mysql' => [
               'host' => env('DB_HOST', 'localhost'),
               'database' => env('DB_DATABASE', 'forge'),
               'username' => env('DB_USERNAME', 'forge'),
               'password' => env('DB_PASSWORD', ''),
           ],
       ],
   ];
   

3. Use configuration files to store complex configuration values:
- Create separate configuration files for complex configurations[4].
- In your main configuration file, use the `Config::get()` function to retrieve the values from the separate configuration files[4].

Example:

php
   // config/mypackage.php
   return [
       'options' => Config::get('mypackage.options'),
   ];
   

By following these approaches, you can handle complex logic in your Laravel configuration files without using Closures, which are not serializable and can cause issues when caching the configuration.
