How can the order of execution of PHP files impact the display and functionality of a webpage with multiple modules?

The order of execution of PHP files can impact the display and functionality of a webpage with multiple modules if certain modules rely on variables or functions defined in other modules. To solve this issue, you can use include or require statements to ensure that files are included in the correct order. 

<?php
// Include files in the correct order
require_once 'module1.php';
require_once 'module2.php';
require_once 'module3.php';

// Rest of the code
?>
