Triggering PHP events based on information that comes through a websocket

[Dirk83]

Hi,

 

I am listening to a 3rd party websocket and now I want a PHP script to be triggered when new information comes through over the websocket without sending a whole new HTTP request (though it might want to trigger an HTTP request).

 

How can I do this?

 

Thanks, Dirk

You might have to give more information about your setup. Is the websocket open on the same server as your PHP script? Is the websocket open using PHP?

No, it is a 3rd party websocket, so the websocket is not running on the same server as the PHP script.

 

I could install a websocket on my own server though in order to send messages from the 3rd webparty indirectly through my browser client to my own web server; in the case that that is necessary.

 

Basically, when new information comes through from the 3rd party websocket I want my own server to perform calculations with the new data and possibly generate an HTTP request based on that. I am also open to suggestions to have all calculations performed on the web browser client and that the web browser client triggers an HTTP request through a javascript.

Does that clarify a bit? It is for a trading system, I listen to price data from an external web server (continuous through a websocket), then I want to perform calculations with them and if it triggers an event I want to cancel, update or place an order through an HTTP request.

Any suggestions?
