PHP implementation of WeChat public number development of micro-letter Red Envelope method

This article mainly introduced the PHP public number development of the red envelope implementation method, combined with the case form analysis of PHP implementation of the public red envelope delivery function of the implementation of ideas, steps and specific operating skills, the need for friends can refer to the next

This paper introduces the implementation method of red envelopes in PHP public number development. Share to everyone for your reference, as follows:

These days encountered a customer to give them a public platform to add cash red envelopes function, is a two times the development of the function, handy Baidu, originally not complex. began to develop the function. The development process and requirements are now posted to share:

A. Requirements:

Fans click on their company's order on the customer's public platform, then return five yuan to the order and send it to the number on the order.

Two. Development ideas:

1: The first to get attention to this fan Openid,openid is to focus on a public ID, so that you can locate this person is the operator of the order.

2: Send the XML data request server.
