What is the MVC architectural pattern, and how do the Model, View, and Controller components each play a distinct role in a PHP application? What is the role of a Controller in the MVC pattern, and what responsibilities should typically be kept out of a controller to maintain good separation of concerns? How do Models in MVC represent both data structure and business logic, and how does this differ from a Model being purely a simple database representation? How does a typical request flow through an MVC based PHP application, from the initial incoming HTTP request to the final rendered response? How does the concept of a Service Layer complement traditional MVC by providing an additional place for complex business logic that spans multiple models? How should a large, complex PHP application evolve its architecture beyond basic MVC to maintain organization and testability as the codebase and team grow significantly?

How do Views in MVC separate presentation logic from application logic, and what role do templating engines like Blade play in this separation?

Intermediate

Answer

Views are responsible purely for presenting data to the user, typically as HTML, and should contain minimal logic beyond simple conditionals and loops needed for basic display purposes, such as iterating over a list of products, with templating engines like Blade or Twig specifically designed to enforce this separation by providing a limited, presentation focused syntax rather than the full power of raw PHP, discouraging developers from accidentally embedding significant business logic directly within a view template.
@foreach ($products as $product)
    <div>{{ $product->name }} - {{ $product->formattedPrice }}</div>
@endforeach
Real-world example A product listing view simply iterates over an already prepared collection of products and displays each one's name and pre formatted price, with all of the actual price formatting logic properly handled elsewhere, such as within the Product model itself, rather than being calculated directly inside the view.
