Explain
Symfony provides a structured architecture based on MVC (Model-View-Controller) principles.
Includes reusable components for routing, forms, security, templating, caching, and more.
Supports rapid development with built-in development tools, debug utilities, and profiler.
Highly extensible via bundles, plugins, and third-party integrations.
Widely used in enterprise-grade PHP applications and open-source projects.
Core Features
Routing and controller system
Form handling and validation
Security system with authentication & authorization
Caching and session management
Logging, profiler, and debugging tools
Basic Concepts Overview
Bundle - modular package containing code, templates, and services
Controller - handles HTTP requests and returns responses
Service - reusable PHP object managed by the container
Routing - maps URLs to controllers
Entity - represents a database record using Doctrine ORM
Project Structure
config/ - application configuration
src/ - PHP classes including controllers and services
templates/ - Twig templates
public/ - web-accessible assets (CSS, JS, images)
var/ - cache, logs, and temporary files
Building Workflow
Create controllers to handle requests
Define routes for URLs
Use Doctrine ORM to manage database entities
Implement services for business logic
Use Twig templates for rendering views
Difficulty Use Cases
Beginner: small CRUD app with a single controller
Intermediate: multi-entity app with forms and validation
Advanced: API with authentication, events, and services
Expert: large-scale enterprise application with multiple bundles
Enterprise: microservices architecture or decoupled Symfony apps
