PHP Master | Functional Programming in PHP
Article Introduction：Many programmers like to talk about functional programming, but if you ask them if they have actually used it, most of the answers will be "no".

Therefore, this article will explain some important concepts of functional programming and how to write functional code in PHP.
Key Points
Functional programming treats calculations as evaluation of mathematical functions, and avoids state and mutable data, treating functions as first-class citizens. This means that functions can be used like values ??in imperative programming.
Key concepts of functional programming include invariance (once defined, the value of a variable cannot be changed), recursion (used frequently due to invariance), pure functions (functions without side effects)
