Building web apps and APIs

Create real applications with PHP.

📖 Key ideas

  1. Structure apps with MVC.
  2. Return JSON: header("Content-Type: application/json"); echo json_encode($data);
  3. Frameworks: Laravel, Symfony, CodeIgniter.
  4. Call other APIs with cURL or Guzzle.
  5. Use .env files for configuration.
💡 Real-life example: A framework is a ready building frame: you fill rooms instead of pouring foundations.
