href » Photon
Photon is an interesting new PHP application server. Instead of running
on the traditional
mod_php stack, it runs behind Mongrel2 and uses
ZeroMQ for message passing. This allows it to do a number of things that
PHP is traditionally bad at (long-polling clients, backgrounding, streaming).
The project is still pre-alpha, but worth keeping an eye on if you are doing heavy PHP development.
