[erlang-questions] Extending PHP with Erlang/YAWS.
Sun Sep 17 15:22:54 CEST 2006
I need to extend a PHP application with some Erlang-based server
functionality. More specifically, the Erlang app's role is to provide some
services for which non-trivial state must be maintained, and which will be
queried by an AJAX client periodically (the client is currently being
written using PHP as the "primary" backend - there is a chance that YAWS
could be accepted as the server for that part, but probably not at this
So, my question is this: how should one perform such integration? The
methods I've basically come up with are:
1) Open a socket from a PHP script and query the Erlang backend using a
proprietary protocol (the queries are simple, but might return a couple KB).
Is JSON generally more convenient for relatively flat datastructures?
JSON/other response data).
3) As (1) but extend the PHP interpreter so it opens a persistent
connection. Does anyone know how hard this might be? AFAIK Apache threads
are mapped to PHP threads, which "share nothing". Is this correct?
4) Somehow get Management to agree on moving the entire AJAX bit to YAWS
(unlikely). In this case, I would open a separate socket for YAWS.
