I wanted to create a web chat. It was suggested that i use Php Socket Servers. I’ve made one and they function well with a telnet client.
What i find myself bamboozled by is how to get that data to the client via ajax (no page refreshes).
All I can come up with is calling a php file with ajax, getting the data and updating the page. But that will not work the other way around.
Or am i missing something?
How would you implement a 1 on 1 web chat?
One solution is long-polling. The client will open up an AJAX request to a script that will block and wait for data to come in. If no data comes in within a minute, it will return and the client will reopen the connection. If data comes in, then it will immediately return the data and the client will update its view.
For sending the data, just do a normal AJAX callback.
