WeChat red envelope interface API implementation (php version)

: This article mainly introduces the API implementation of the red envelope interface (php version). If you are interested in the PHP Tutorial, please refer to it. More please support: http://www.webyang.net/Html/web/article_245.html

I. red envelope document description

Currently, red packets are divided into two types: cash red packets and fission red packets.
1, cash red envelope: https://pay.weixin.qq.com/wiki/doc/api/cash_coupon.php? Chapter = 13_5
2, fission red envelope: https://pay.weixin.qq.com/wiki/doc/api/cash_coupon.php? Chapter = 16_5

II. php interface implementation
This article explains how to call a cash red envelope. The rest is basically the same, so I will not try it.
