Logging for region and environment specific success and error messages with standardized code numbers

Localization Manager:

We have implemented a LocalizationManager class responsible for handling localization (translation) of messages and error codes. This class is initialized with the base directory, environment (dev or prod), default locale, and a cache object.

It can load constants from various PHP files. It can get localized strings using getLocalizedString. It has a dynamic mode for defining constants dynamically. It defines constants using initialize() and defineDynamicConstants() methods.

Cache?

We have a LocalizationCache class that provides caching functionality for the LocalizationManager. It allows us to cache localized strings to improve performance.

Logger:

We have implemented a Logger class responsible for logging activities in the system. It logs activities like user logins, logouts, and other events to a database table named activity_log.

Error codes and Constants

We have defined error codes and constants for different HTTP status codes and messages. These constants are used throughout our code for consistent error handling.

Feedback Functions

We defined functions for displaying feedback messages, trimming file paths for error reporting, and handling different types of messages (errors, warnings, and successes).

Response Handling

We have functions for sending responses with appropriate HTTP status codes and messages. These functions are used to communicate with clients when handling requests.

Logger vs LocalizationManager

We integrate these components into our application logic, such as authentication and error handling, using the defined constants and functions. The LocalizationManager handles translations, and the Logger records activities.
