In PHP, streams are a versatile tool that abstracts I/O operations. A stream refers to a resource object that represents a sequence of data, which you can either read from or write to.
Streams serve various purposes, including:
1.Reading and writing files: Streams offer a standardized approach to read from and write to files, regardless of the underlying file system.
2.Network communication: You can use streams to communicate with remote servers over various network protocols like HTTP, FTP, etc.
3.Data manipulation: Streams can be used to process data in memory or in transit, such as compressing or encrypting data.
4.Custom protocols: Streams provide a mechanism to implement custom protocols for handling data.
In PHP, streams are implemented using the stream_ * family of functions, which lets you create, open, read, write, and close streams, as well as perform other operations on them.
PHP supports a wide range of built-in stream types, including file, memory, and network streams. Moreover, you can create custom stream wrappers to use streams with non-standard protocols or data sources.
