How to send data from the browser with minimal traffic costs?
The string can be sent 10 or more times per second:
prm=1...
Server response is not needed.
As a result, the header is more overlaid than the data. Interests, whether there is an opportunity to send heading, and further on keep-alive to send the data.
I heard about websocket. How to attach a script to Apache, preferably without running a php script as a daemon.

Answer 1

To begin with, no typical php hosting (shared hosting) can withstand such packet bombardment. Each EULA contains a clause on which a ban follows for this. Here you need at least a good vds.
Further, if there is vds, then there is nginx on it (Apache was created for other tasks). Nginx can handle packet bombardment and can filter and proxy websocket .
Further, behind the back of nginx, you can put any websocket server in any language, even in PHP - although this is not the best choice for serious workloads, its developers clearly did not count on a stream of > 10 packets per second from each client.
