What are the consequences of separating code into multiple files for handling different aspects of form processing in PHP applications?

Separating code into multiple files for handling different aspects of form processing in PHP applications can improve code organization, readability, and maintainability. It allows for better modularization of code, making it easier to manage and update specific functionalities without affecting the entire application. Additionally, splitting code into separate files can help reduce the chances of conflicts and errors by isolating different parts of the form processing logic. 

// index.php
<?php
require 'form_validation.php';
require 'form_submission.php';

// Rest of the code for form processing
?>
