How can PHP beginners effectively organize their functions within a file?

PHP beginners can effectively organize their functions within a file by grouping related functions together and using comments to label each group. This makes it easier to find and understand the purpose of each function. Additionally, beginners can use whitespace and indentation to visually separate different sections of code, making it more readable.

<?php

// Group of functions related to user authentication
function login() {
    // Function code here
}

function logout() {
    // Function code here
}

// Group of functions related to database operations
function fetch_data() {
    // Function code here
}

function update_data() {
    // Function code here
}

?>
