KLYRO is a complete Razorpay payment integration solution developed in PHP 8.0+ that enables you to accept secure online payments through a streamlined checkout experience with premium dark luxury design.

The solution handles the full Razorpay payment lifecycle including session initialization, payment processing, success confirmation, and cancellation handling. It stores all transaction details in a MySQL database with prepared statements, providing an additional layer of security for transaction validation and record-keeping.

The interface features an ultra-premium dark theme with 24K gold accents, animated gradients, and professional typography. It's fully responsive across all devices from mobile (320px) to 4K displays, with optimized performance delivering page loads under 1 second.

KLYRO supports all Razorpay payment methods including credit/debit cards, UPI (Google Pay, PhonePe, Paytm), net banking, digital wallets, and international cards. The clean PHP code follows PSR-12 standards with no external dependencies, making it easy to customize and integrate into existing projects.

Complete documentation is included with step-by-step setup instructions, security verification guides, customization examples, and troubleshooting for common issues. Special guidance is provided for Pakistan-based developers requiring VPN access during testing.
