php怎么实现在线直播功能？
php 七牛云实现直播功能：
一：最近在做一个直播卖货的项目，后台搭建好了准备接入直播，搜了几家阿里，TX和七牛，结果阿里的直播php只有代码没有文档，TX的我朋友说代码比较乱就不考虑了，上了七牛注册了一个账户，申请直播空间的时候被域名卡主了，已经备案的域名还要再网站公安备案一次

又搜了搜发现涉及网络表演业务的，需办理《网络文化经营许可证》，请咨询当地人民政府文化行政部门，等待申请完以后在进行下一步。
二：域名备案终于好了，开始搞第二步，实现直播功能，移动端可以参考七牛云SDK，下面是服务端推流案例，本次使用的是rtmp流实现直播，在控制台找到直播云服务，创建直播云空间
创建好直播空间后会生成几个二级域名，按需要将域名解析出来，然后就到了下面的样子
代码运行起来后会在直播流中看到你说创建的直播流播放历史等信息
安装composer包
php composer.phar require qiniu/php-sdk
再vendor/pili-engineering/pili-sdk-php.v2里能找到两个案例，一个是直播的，一个是连麦的，这次先实现直播，下一篇再更新一下连麦
