Published on the entire WeChat public platform and failed to pass the test

I’ve been working on it for a day, but I still haven’t passed the test. I checked a lot of information, but I still don’t understand

I wrote down the received data log in the entry file, as follows:

I haven’t seen the message XML mentioned in the developer documentation, and I don’t know how to obtain it.
The developer documentation says to push event messages to a dedicated test public account. How to write push events
This is my first time doing WeChat development. I hope you can give me some advice. I did this just to pass the test
Thank you all in advance

I didn’t see the message XML mentioned in the developer documentation, and I don’t know how to get it:

<code>$postStr = file_get_contents("php://input");
$array = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);</code>
