Is php not suitable for long connections?
Article Introduction:PHP is a widely used server-side programming language suitable for a variety of application scenarios. In terms of network communication, long link technologies like WebSocket require a continuous connection and are therefore very different from PHP's short link model. This has also led many people to believe that PHP is not suitable for long connections. However, in actual applications, although PHP is a short connection model, we cannot deny that PHP has some solutions suitable for long connection scenarios. Below we will discuss the feasibility and implementation of PHP long connections. ### Long connection and short connection

How to implement long connection communication in PHP?
Article Introduction:How to implement long connection communication in PHP? In traditional web applications, short connections are usually used for communication. Whenever a client sends a request to the server, the server processes the request and returns a response, then immediately disconnects. In some specific application scenarios, such as real-time chat, push messages, etc., long connections need to be implemented for real-time data interaction. This article will introduce how to implement long connection communication in PHP, with code examples. To implement long connections in PHP, you can use the following two common technologies: polling and WebSo
