php怎么实现主动发送消息到终端
php如何实现主动发送消息到终端
现在有一个这样的应用场景，有一个php做后台的信息发布系统控制端，用来控制户外的信息发布终端（广告机，户外显示屏等），当客户在浏览器页面上点击重启，开关机时或做其他操作，我如何将这个信息主动发送给终端呀？
看了一些推送的办法，还是云里雾里，很多还是要终端先发送请求才可以，哪位大侠能指点一下吗？
------解决方案--------------------
对,这个就看你的"广告机，户外屏"这些是如何和你的php server联系的.
php里有socket库, 不过其它方式也很多,不一定需要
------解决方案--------------------
换成我的话我肯定不会用php做，如果非要的话 php可以做为一个前台,再写一个服务器端来接收php的输入数据进行控制。或者直接开发服务器端和客户端，抛开php.
也许php是固定的，你也可以在前端和你的后端(广告机上)都架设php来传递数据 呵呵，广告机其实也是个win操作系统.简单些直接post get 之后处理 这就简单多了吧...将事件处理成bat文件来调用...
