What are best practices for organizing PHP code into separate files for easier troubleshooting?

Organizing PHP code into separate files can make troubleshooting easier by breaking down the code into smaller, more manageable chunks. One common approach is to separate different functionalities into separate files, such as one file for database operations, another for user authentication, and so on. This not only makes it easier to locate and fix issues but also promotes code reusability and maintainability. 

// db_operations.php
<?php

function connectToDatabase() {
    // Code to connect to the database
}

function fetchUserData($userId) {
    // Code to fetch user data from the database
}

?>

// auth.php
<?php

function authenticateUser($username, $password) {
    // Code to authenticate user credentials
}

function logoutUser() {
    // Code to log out the user
}

?>
