What potential pitfalls should be considered when using PHP includes for organizing website components like menus and headers?

One potential pitfall when using PHP includes for organizing website components like menus and headers is the risk of naming conflicts if the included files have variables or functions with the same name. To avoid this issue, it's important to properly scope your variables and functions within the included files using namespaces or unique naming conventions. 

// Example of scoping variables within an included file
// header.php
<?php
$siteName = "My Website";
?>

// menu.php
<?php
$menuItem = "Home";
?>

// index.php
<?php
include 'header.php';
include 'menu.php';

echo $siteName; // Output: My Website
echo $menuItem; // Output: Home
?>
