What are potential pitfalls when using multiple includes and variables in PHP for external pages?

Potential pitfalls when using multiple includes and variables in PHP for external pages include variable scope issues, naming conflicts, and code readability problems. To solve these issues, it is recommended to use namespaces or classes to encapsulate variables and functions, ensuring they do not conflict with other parts of the codebase. 

<?php
// Using namespaces to encapsulate variables and functions
namespace MyNamespace;

// Include external page with variables and functions
include 'external_page.php';

// Access variables and functions from external page using namespace
echo MyNamespace\$variable;
MyNamespace\myFunction();
?>
