Swoole:面向生产环境的 PHP 异步网络通信引擎
使 PHP 开发人员可以编写高性能的异步并发 TCP、UDP、Unix Socket、HTTP,WebSocket 服务。Swoole 可以广泛应用于互联网、移动通信、企业软件、云计算、网络游戏、物联网(IOT)、车联网、智能家居等领域。使用 PHP + Swoole 作为网络通信框架,可以使企业 IT 研发团队的效率大大提升,更加专注于开发创新产品。

好了各位,以上就是这篇文章的全部内容了,能看到这里的人呀,都是人才。之前说过,PHP方面的技术点很多,也是因为太多了,实在是写不过来,写过来了大家也不会看的太多,所以我这里把它整理成了PDF和文档,如果有需要的可以
更多学习内容可以访问【对标大厂】精品PHP架构师教程目录大全,只要你能看完保证薪资上升一个台阶(持续更新)
以上内容希望帮助到大家,很多PHPer在进阶的时候总会遇到一些问题和瓶颈,业务代码写多了没有方向感,不知道该从那里入手去提升,对此我整理了一些资料,包括但不限于:分布式架构、高可扩展、高性能、高并发、服务器性能调优、TP6,laravel,YII2,Redis,Swoole、Swoft、Kafka、Mysql优化、shell脚本、Docker、微服务、Nginx等多个知识点高级进阶干货需要的可以免费分享给大家,需要的可以加入我的 PHP技术交流群
在面试时用php+swoole编写了一个简易聊天室,面试官让我明天来上班!
