PHP Alipay payment related issues

The website has encountered Alipay payment problems in the past two days. When the user pays with Alipay, it prompts that the payment is successful, and then the status in the parameter information returned by Alipay is: [status] => WAIT_PAY
The merchant account has received the payment received by the user Pay! May I ask what is the reason for this? Please give me some advice....
