php7处理方案
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。
安装 Libevent 库
php event 扩展 依赖 Libevent 库,需要先编译安装(注意是 Libevent 库,非 libevent 扩展)。
|
git clone --depth=1 https: //github .com /nmathewson/Libevent .git cd Libevent . /autogen .sh . /configure --prefix= /usr/local/libevent make && make install |
安装 Event 扩展
可以直接使用 pecl 安装

pecl install event downloading event-2.5.3.tgz ... Starting to download event-2.5.3.tgz (140,913 bytes) ..............................done: 140,913 bytes 50 source files, building running: phpize Configuring for : PHP Api Version: 20180731 Zend Module Api No: 20180731 Zend Extension Api No: 320180731 Enable internal debugging in Event [no] : Enable sockets support in Event [yes] : libevent installation prefix [/usr] : /usr/local/libevent ...
