Editor to share with you how to install PHP7 event extension, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
PHP7 installs the event extension
Libevent is a lightweight open source high-performance Imax O framework written in C language, which supports a variety of Imax O multiplexing technologies: epoll, poll, dev/poll, select and kqueue, etc.; supports events such as Imax O, timers and signals; registers event priority. PHP provides the corresponding extensions libevent and Event.
Compared with libevent ext, event ext has better performance and more comprehensive API, which allows us to use Libevent more amicably.
Install the Libevent library
The php event extension depends on the Libevent library and needs to be compiled and installed first (note that it is the Libevent library, non-libevent extension).
