What are some best practices for including functions in PHP scripts?

When including functions in PHP scripts, it is best practice to define the functions in a separate file and then include that file in the main script using the `include` or `require` statement. This helps keep the code organized and makes it easier to reuse functions in multiple scripts. Additionally, it is recommended to use function names that are descriptive and follow a consistent naming convention to make the code more readable and maintainable. 

// functions.php
function greet($name) {
    return "Hello, $name!";
}

// main.php
include 'functions.php';

echo greet('John'); // Output: Hello, John!
