The document provides an overview of streams, which are bodies of water with a current, and details on various types of streams and their characteristics. It also outlines functions related to PHP file handling, such as opening files, reading contents, and managing file streams, alongside examples of using different wrappers. Additionally, it discusses the implementation of custom stream wrappers and file operations in PHP.
![A stream is a body of water
[1]
with a current,
confined within a bed and stream banks.
Depending on its location or certain
characteristics, a stream may be referred to
as a branch, brook, beck, burn, creek, crick,
gill (occasionally ghyll), kill, lick, mill race, rill,
river, syke, bayou, rivulet, streamage, wash,
run, or runnel.
