This article mainly introduces the cash red envelope development of php WeChat public account in detail. It has certain reference value. Interested friends can refer to it.

The example of this article is to share php WeChat with everyone. The specific code of the public account’s cash red envelope is for your reference. The specific content is as follows

The following reference to the development of cash red envelope in WeChat payment is from the WeChat payment development document, as shown in the figure below.

Cash red envelope is one of the marketing tools provided by the WeChat Pay merchant platform. It has been deeply loved by merchants and users since its launch. Merchants can issue cash red envelopes to WeChat Pay users through this platform. After the user receives the red envelope, the funds arrive in the user's WeChat Pay change account and have the same use exit as other funds in the change wallet; if the user does not receive the red envelope, the funds will be returned to the merchant's WeChat Pay account after 24 hours.

The following is the code snippet I used to test WeChat payment for sending red envelopes, for reference only.
