socket.io + php +在这个时候是一个现实的解决方案

Question

I have been reading about websockets and also about socket.io.

I understand websockets are not support but enough browsers yet to be realistically used.

socket.io has browser support but appears to need node.js. With my hosting solution I have some space on a shared server, very limited control over the server and have access to php but there is no node.js.

I have read that people can get socket.io to work with PHP.

Question: seeing I have very limited server access, not control over ports, command line etc is it realistic that I could get socket.io working with PHP or should I just stick with the AJAX calls (I'm currently using)?

Note: I've developed a chat solution and it appears it would be much more light weight if it was running with a socket solution.

Also - is there good security with Sockets.io?

thx

Answer 1

Trying to make PHP talk to socket.io I suspect will be a big task.

Certainly it's not a great idea to run websockets via a pre-fork or threaded apache. Any event based server should be OK if you can handle the number of PHP processes. A better approach would be to write an event based server in php. Like this one
