+Libevent bindings for PHP
+=========================
+
+[![Build Status](https://travis-ci.org/expressif/pecl-event-libevent.svg)](https://travis-ci.org/expressif/pecl-event-libevent)
+
+Libevent is a library that provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached.
+
+More information about Libevent can be found at » http://libevent.org/.
+
+--
+**NOTE :** This fork is the port of the module to [PHP7 / PHPNG](https://wiki.php.net/phpng-upgrading) 
+
+
+## Requirements 
+
+This extension requires [» libevent](http://libevent.org/) library. Minimal required version is 1.4.0.
+
+## Installation 
+
+Information for installing this PECL extension may be found in the manual chapter titled [Installation of PECL extensions](http://php.net/manual/en/install.pecl.php). Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » http://pecl.php.net/package/libevent.
+
+## Compile from sources
+
+Pre-requisites (only for linux) :
+
+```sh
+sudo apt-get install php7.0-dev gcc make libevent-dev
+```
+
+Compile sources :
+
+```sh
+git clone https://github.com/expressif/pecl-event-libevent.git
+cd pecl-event-libevent
+phpize
+./configure
+make && sudo make install
+```
+
+## Predefined Constants
+
+The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
+
+* EV_TIMEOUT (integer)
+* EV_READ (integer)
+* EV_WRITE (integer)
+* EV_SIGNAL (integer)
+* EV_PERSIST (integer)
+* EVLOOP_NONBLOCK (integer)
+* EVLOOP_ONCE (integer)
+
+## Examples
+
+Example #1 polling STDIN using basic API
+
+```php
+<?php
+
+function print_line($fd, $events, $arg)
+{
+    static $max_requests = 0;
+
+    $max_requests++;
+
+    if ($max_requests == 10) {
+        // exit loop after 10 writes
+        event_base_loopexit($arg[1]);
+    }
+
+    // print the line
+    echo  fgets($fd);
+}
+
+// create base and event
+$base = event_base_new();
+$event = event_new();
+
+$fd = STDIN;
+
+// set event flags
+event_set($event, $fd, EV_READ | EV_PERSIST, "print_line", array($event, $base));
+// set event base
+event_base_set($event, $base);
+
+// enable event
+event_add($event);
+// start event loop
+event_base_loop($base);
+```
+
+Example #2 polling STDIN using buffered event API
+
+```php
+<?php
+
+function print_line($buf, $arg)
+{
+    static $max_requests;
+
+    $max_requests++;
+
+    if ($max_requests == 10) {
+        event_base_loopexit($arg);
+    }
+
+    // print the line
+    echo event_buffer_read($buf, 4096);
+}
+
+function error_func($buf, $what, $arg)
+{
+    // handle errors
+}
+
+$base = event_base_new();
+$eb = event_buffer_new(STDIN, "print_line", NULL, "error_func", $base);
+
+event_buffer_base_set($eb, $base);
+event_buffer_enable($eb, EV_READ);
+
+event_base_loop($base);
+```
