In websockets.php I would create a conditional statement that checks whether the button was clicked (on/off settings from the database). Some pseudo-code:

As I understood, you need to execute the command via php script. You can do so using shell_exec or exec. See documentation here:
exec
shell_exec

Example:
shell_exec("/path/to/php /var/www/html/index.php welcome index '".$parmeter1."' '".$parmeter2."' >> /path/to/logs/welcome.log &");

If you want to run the command in background then it is important to put & at the end.

The extra variables surrounded in single quotes after the path to the script are optional. You can omit them if not needed.

I recently had the same problem. Here is what I found out:

Normal HTTP responses can contain Access-Control-Allow-Origin headers to explicitly allow other websites to request data. Otherwise, web browsers block such "cross-origin" requests, because the user could be logged in there for example.

This "same-origin-policy" apparently does not apply to WebSockets and the handshakes can't have these headers. Therefore any website could connect to your Sony device. You probably wouldn't want some website to set your speaker/receiver volume to 100% or maybe upload a defective firmware, right?

That's why the audio control API checks the Origin header of the handshake. It always contains the website the request is coming from.

The Python WebSocket client you use assumes http://192.168.0.34:54480/sony/avContent as the origin by default in your case. However, it seems that the API ignores the content of the Origin header and just checks whether it's there.

The WebSocket#connect method has a parameter named suppress_origin which can be used to exclude the Origin header.

TL;DR

The Sony audio control API doesn't accept WebSocket handshakes that contain an Origin header.

You can fix it like this:
