PHP functions are blocks of reusable code that can be called multiple times within a program to perform specific tasks. Functions in PHP provide a way to organize code and make it more modular, allowing for easier maintenance and reusability. They can take inputs, known as parameters, perform operations on them, and then return outputs. PHP functions can be either built-in or user-defined, and they can have their own scope, meaning variables declared inside a function are different from those declared outside. Functions are essential in PHP for enhancing code readability, reducing redundancy, and improving overall program efficiency.
