How can incorrect path configurations affect the display of a confirmation code in PHP?

Incorrect path configurations can prevent PHP from properly locating and including necessary files, such as those containing functions to generate or display confirmation codes. This can result in the confirmation code not being displayed or generated as expected. To solve this issue, make sure that the paths to the required files are correctly specified in the PHP code.

<?php
// Incorrect path configuration
include 'functions.php'; // Assuming functions.php contains code to generate/display confirmation codes

// Correct path configuration
include '/path/to/functions.php'; // Specify the correct path to functions.php
?>
