Subscription System

A lightweight PHP-based subscription system that allows users to sign up using their email, verify through a code, and then receive a random XKCD comic every day. A scheduled CRON job runs every 24 hours to fetch a new comic and deliver it to all verified subscribers.

🚀 Features

• Email registration & verification
• Daily comic delivery using the official XKCD JSON API
• Automatic CRON execution every 24 hours
• Simple, clean PHP implementation
• Easy to deploy on any server
• No heavy frameworks required

🔧 How the System Works

1. A user enters their email on the subscription page.
2. The system generates a verification code and emails it to the user.
3. After verification, the user becomes an active subscriber.
4. A CRON job runs daily:
   • Fetches a random XKCD comic
   • Extracts the title, image, alt-text, and link
   • Sends the comic to every subscriber
5. The process repeats automatically every 24 hours.
