PHP WeChat official account randomly distributes cash red envelopes

This time I will bring you the function of php WeChat official account to randomly distribute cash red envelopes. What are the precautions for the function of php WeChat official account to randomly distribute cash red envelopes? The following is a practical case, let’s take a look.

The following development of cash red envelopes in WeChat payment refers to 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.
