PHP realizes the method of developing WeChat cash red envelope function

This article mainly introduces the development of PHP cash red envelope function, combined with the case form more detailed analysis of PHP using the interface to achieve cash red envelope function of the relevant steps and operation skills, the need for friends can refer to the next
