REST API – Essential Concepts 🚀

1️⃣ Fundamentals of REST API

REST (Representational State Transfer) – Architectural style for web services.

Statelessness – Each request is independent, no session stored on the server.

Client-Server Architecture – Separation of frontend and backend.

Cacheability – Responses can be cached for performance optimization.


2️⃣ HTTP Methods (CRUD Operations)

GET – Retrieve data (Read).

POST – Create new data (Create).

PUT – Update existing data (Update).

PATCH – Partially update data (Modify).

DELETE – Remove data (Delete).


3️⃣ API Endpoints & URL Structure

Resource Naming – Use plural nouns (/users, /orders).

Hierarchical Structure – Use nested URLs (/users/{id}/orders).

Query Parameters – Filter results (/products?category=electronics).

Path Parameters – Identify resources (/users/{id}).


4️⃣ Request & Response Format

JSON (JavaScript Object Notation) – Standard format for data exchange.

Headers – Define content type, authentication tokens.

Status Codes –

200 OK – Success.

201 Created – New resource created.

400 Bad Request – Invalid request.

401 Unauthorized – Authentication required.

403 Forbidden – Access denied.

404 Not Found – Resource doesn’t exist.

500 Internal Server Error – Server-side issue.



5️⃣ Authentication & Security

API Keys – Unique keys to access API.

OAuth 2.0 – Secure authorization framework.

JWT (JSON Web Tokens) – Token-based authentication.

Rate Limiting – Prevent API abuse.

CORS (Cross-Origin Resource Sharing) – Control resource access.


6️⃣ REST API Best Practices

Use Proper HTTP Methods – Follow standard conventions.

Handle Errors Gracefully – Return meaningful error messages.

Pagination – Limit data returned (/users?page=1&limit=10).

Versioning – Manage API versions (/api/v1/users).

Idempotency – Ensure repeated requests yield the same results.


7️⃣ Tools & Testing

Postman – API testing and debugging.

Swagger (OpenAPI) – API documentation and visualization.

cURL – Command-line API testing.

Sessions – Store user data across pages (session_start();).

Cookies – Store small pieces of data on the client (setcookie();).


6️⃣ Object-Oriented Programming (OOP) in PHP

Classes & Objects – Define with class and instantiate using new.

Encapsulation – Use public, private, protected.

Inheritance – Extend functionality using extends.

Polymorphism & Interfaces – Create flexible code structures.


7️⃣ File Handling

Reading & Writing Files – fopen(), fread(), fwrite().
