Real time notification in PHP
提问by user3201500
I am creating a PHP application, where I want one user make a database entry. It should be reflected to all the users whoever have this app open on their browser will get instant notification that some data has been updated on the database or with whatever data has been inserted.
我正在创建一个 PHP 应用程序，我希望一个用户在其中创建一个数据库条目。它应该反映给所有在浏览器上打开此应用程序的用户，他们将立即收到通知，指出数据库中的某些数据已更新或已插入任何数据。
Is there any way I can get real time notification of data inserted or updated? On all the opened browser without any delay.
有什么方法可以获得插入或更新数据的实时通知？在所有打开的浏览器上没有任何延迟。
We use AJAX for now. But it seems like our application is now working slow due to continues request. Any other way? Which is free.
我们现在使用 AJAX。但似乎我们的应用程序现在由于继续请求而运行缓慢。还有什么办法吗？哪个是免费的。
Thank you!
谢谢！

You can use web sockets. One existing library example for PHP is Ratchet.

I don't know what do you use on your server side but even if it isn't Laravel, take a look at Jeffrey's Laracast about implementing real time notifications in Laravel (PHP). https://laracasts.com/lessons/pusher-awesomeness
