Alert
=====

[](#alert)

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

#### WHY?

[](#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 eschews such features and provides *only* non-blocking IO and timer events to avoid enforcing OOP slowness on the overlaid application. It's a stripped down, no-frills event reactor without a learning curve that "just works."

#### FEATURES

[](#features)

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

- Pausing/resuming *individual* timers or stream IO observers
- Assigning multiple watchers for individual streams

#### DEPENDENCIES

[](#dependencies)

- PHP 5.4+
- (optional) [*PECL libevent*](http://pecl.php.net/package/libevent "libevent") for faster evented execution and high-volume descriptor reactions. Windows libevent extension DLLs are available [here](http://windows.php.net/downloads/pecl/releases/ "Windows libevent DLLs")

#### INSTALLATION

[](#installation)

###### Git:

[](#git)

```
$ git clone https://github.com/rdlowrey/alert.git
```

###### Manual Download:

[](#manual-download)

Manually download from the [tagged release](https://github.com/rdlowrey/alert/releases "Tagged Releases") section.

###### Composer:

[](#composer)

```
$ php composer.phar require rdlowrey/alert:0.3.*
```
