## What it is
A single-file PHP integration for WeChat Pay covering native QR payments, H5 payments, JSAPI (official account) payments, cash red packets, transfers, and refunds, with a V3 API version. Each payment method is a standalone ~200-line file with no external dependencies, requiring only PHP with CURL and SSL enabled.

## Use cases
- accept WeChat QR code payments on a PHP site
- integrate WeChat H5 mobile payments
- add WeChat JSAPI payments inside the official account browser
- send cash red packets to users via WeChat Pay
- process WeChat Pay refunds and async payment notifications
- quickly prototype WeChat Pay without complex SDK setup

- you only need one or two specific WeChat Pay methods
- you want readable example code to learn the WeChat Pay API flow
