The concept of stream is derived from the concept of piping (pipe) in Unix. In Unix, a pipeline is an uninterrupted stream of bytes used to communicate between programs or processes, or to read and write peripherals, external files, and so on. According to the direction of the flow can be divided into the input and output streams, but also on the periphery of other flows, such as buffer flow, so that more flow processing methods can be obtained.

The stream in PHP and the stream in Java are actually the same concept, just a little bit simpler. Since PHP is primarily used for web development, the concept of "flow" is less mentioned. If you have a Java base, it's easier to understand the flow in PHP. In fact, many of the advanced features in PHP, such as SPL, anomalies, filters, and so on are referenced in the implementation of Java, in the concept and principle of expatiating.
