PHP Library for Validating Telegram Mini App Users
==================================================

[](#php-library-for-validating-telegram-mini-app-users)

This PHP library provides functionality for validating users of Telegram Mini Apps based on the `initData` string sent to the backend by the Telegram Web App. The validation process ensures the integrity of the received data using Telegram's guidelines.
