MVC Pattern in PHP (How Laravel/Symfony Think)

MVC is a design pattern that separates responsibilities:

• Model: data and business rules (database logic)
• View: HTML templates
• Controller: receives request, calls model, returns view

MVC flow (easy picture)

flowchart LR
  A[Browser Request] --> B[Controller]
  B --> C[Model]
  C --> D[(Database)]
  C --> B
  B --> E[View]
  E --> A

Why MVC makes apps easier

Without MVC, pages become messy:

• SQL inside HTML
• logic everywhere
• hard to maintain

With MVC, each part has a clear job.

Mini example (concept)

• PostController.php handles request
• PostModel.php fetches posts
• posts.view.php renders HTML

You do not have to build a full framework to benefit from this structure.
