php7 libevent扩展,PHP7 安装event扩展的实现方法

Libevent 是一个用C语言编写的、轻量级的开源高性能I/O框架，支持多种 I/O 多路复用技术： epoll、 poll、 dev/poll、 select 和 kqueue 等；支持 I/O，定时器和信号等事件；注册事件优先级。PHP提供了对应的扩展 libevent、 Event 。

相比 libevent ext, event ext 拥有更好的性能表现和更全面的API，可以让我们更友好的使用 Libevent。

cd Libevent

./autogen.sh

./configure --prefix=/usr/local/libevent

make && make install
