What are the potential pitfalls of keeping all PHP code in one file versus separating it into multiple files for different tasks?

Keeping all PHP code in one file can lead to a lack of organization, readability, and maintainability. It can become difficult to find and update specific sections of code, and can lead to conflicts or errors when making changes. Separating code into multiple files based on different tasks can improve organization, readability, and allow for easier maintenance and collaboration. 

// Example of separating PHP code into multiple files for different tasks

// File: index.php
require_once 'functions.php';
require_once 'database.php';

// Use functions from functions.php and database connection from database.php
