php - Best way for instant messaging system without Websockets -


i have webserver i'm renting host. don't allow webrtc or node.js or that.

i have messaging system using php/sql/ajax (when user's viewing message thread, fetches new data every 60 seconds) doesn't seem instant , seems it's not convenient server if lot of users on.

so, question is: there way can live-update data users without having request new data , not having use websockets?

i'd implement notifications , comments well, having lot of ajax scripts requesting data every x amount of seconds doesn't seem idea.

personally, suggest best solution problem use websocket. that's effective way far. , regarding this:

they don't allow webrtc or node.js or that.

you can find hosting can allow run websocket servers. example https://www.digitalocean.com can setup/install own socket server in hosting.

i think method use right ajax polling persistently request on every interval new updates in database. okay minimal updates don't recommend using method. @ every request per interval affecting app speed , performance in long run. that's why correct:

and this:

yes, there way using sse (server-sent events). check example w3fools :d.

but in case consider websockets again, may try websocket php: ratchet.
