Where can I find the official demo of the WeChat app payment php backend?

I am working on a project. The demo of WeChat app payment is not found in the official website. Is there a link?

APP can directly interact with WeChat to complete the payment, without going through PHP. .
If your APP is just a shell with an h5 page embedded in it, you can only pay by scanning the QR code or using Alipay.
If your page is opened through an official account, then use the official account to pay.

You can refer to ：http://www.php.cn/course/364.html

The above is where to find the official demo of the WeChat app payment PHP background. For more related content, please pay attention to the PHP Chinese website (www.php.cn )!
