What are the potential pitfalls of moving PHP files to subdirectories within a website?

Moving PHP files to subdirectories within a website can potentially break any links or references to those files, leading to errors or missing content on the website. To solve this issue, you can update the file paths in your code to reflect the new directory structure.

// Before moving PHP files to subdirectories
include 'file.php';

// After moving PHP files to subdirectories
include 'subdirectory/file.php';
