In PHP, a function is a block of code that performs a specific task and can be called by other parts of the program. Functions can accept input in the form of parameters and can return a value or output.

Functions help to organize and reuse code, making it easier to maintain and update a PHP program.

Functions are defined using the keyword “function” followed by the function name and a set of parentheses.

The code to be executed is placed within curly braces {}.
