Alert

Alert provides native and libevent event reactors for powering event-driven PHP applications and servers.

WHY?

Buffer and event-emmitter abstractions -- though user-friendly -- are unfortunately slow in userland. Performant PHP servers cannot compete (in terms of speed) with the likes of Node.js where such features are compiled. Alert avoids these features and provides only non-blocking IO, timer and signal events to prevent OOP slowness in the overlying application. It's a stripped down, no-frills event reactor that "just works."

FEATURES

Alert adds the following functionality to PHP's non-blocking IO space:

• Pausing/resuming individual event/signal/IO observers
• Assigning multiple watchers for individual streams

DEPENDENCIES

• PHP 5.4+
• (optional) php-uv for libuv backends.
• (optional) PECL libevent for libevent backends. Windows libevent extension DLLs available here
