MVC (Model-View-Controller) Architecture

MVC (Model-View-Controller) is a design pattern used in software development to separate concerns within an application. It divides an application into three interconnected components—Model, View, and Controller—to improve organization, maintainability, and scalability.

Components of MVC

1. Model (Data & Business Logic)

- Represents the data and the business logic of the application.

- Manages data retrieval, storage, and processing.

- Independent of user interface (UI).

2. View (User Interface - UI)

- Defines how the data is presented to the user.

- Handles UI elements like buttons, forms, and displays.

- Does not contain business logic—only renders data from the Model.

3. Controller (Request Handling & Business Logic Execution)

- Acts as a bridge between Model and View.

- Receives user input, processes it, and updates the Model or View accordingly.

- Controls the flow of data in the application.

Advantages of MVC

- Separation of Concerns – Keeps logic, UI, and user interactions separate for better organization.

- Scalability – Easily extend or modify different components without affecting others.

- Code Reusability – Reuse Model and View components across multiple applications.

- Maintainability – Cleaner code structure makes debugging and updates easier.

Errors

It is a good idea to send errors in production environment to error log. Errors may contain sensitive information. Even so errors maybe helpful to development team or to QA team, errors need to be suppressed in production environment for viewing by everyone. Errors are good way to troubleshoot an issue therefore only trusted people can have access to this information. If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...

goto PHP operator

goto operator will skip execution of code and continue execution of a code that follows a label to which goto operator points to. If code has many goto operators, than this code probably needs a revision. It is possible to write code that executes without goto operators.
