Real Time¶
Real time generally refers to the ability of an application to process data with minimal delay or in a continuous manner, often appearing instantaneous to the user.
This is the case with streams of data, chat systems, notifications, dashboards, collaborative tools, etc.
However, PHP itself is not inherently a real-time language due to its traditional request-response model.
There are several technologies that are paired with PHP to achieve real-time features; Polling, websockets, Server Sent Events or SSE, asynchronous PHP.
See also Building Real-Time Applications with PHP and WebSockets, php-via and Ratchet.
