📖 Key API Concepts
- Use
header('Content-Type: application/json') to tell clients the response is JSON.
- Prepare your data as an array or object in PHP.
json_encode() converts PHP arrays/objects into JSON strings.- APIs return data — no HTML or UI, just raw JSON or other data formats.
- Clients (frontend apps, mobile, other servers) fetch and consume this JSON.
💡 Tip: In real APIs, validate input, handle errors, and authenticate requests for security.
