Asynchronous framework in PHP. It has a huge number of features. Designed for highload. Each worker is capable of handling thousands of simultaneous connections. Main features and possibilites:

  • Powerful servers: HTTP, FastCGI, FlashPolicy, Ident, Socks4/5.
  • Many bundled clients like DNS, MySQL, Postgresql, Memcache, MongoDB, Redis, HTTP, IRC, Jabber, ICMP, Valve games client, etc.
  • Asynchrounous Filesystem I/O (using eio).
  • Many useful built-in applications like CGI.
  • Interactive debug console.
  • Dynamic spawning workers.
  • Chroot & Chdir for workers.
  • Automatic graceful reloading user's scripts when it's updated.
  • Graceful worker shutdown (and re-spawn if necessary) by the following limits: memory, query counter, idle time.

Master process understands signals:

SIGHUP - update config from file.
SIGUSR1 - reopen log-file.
SIGUSR2 - graceful restart all workers.
