What are the potential challenges of integrating a forum into a CMS using PHP, specifically in terms of handling variables that may overlap between the two systems?

When integrating a forum into a CMS using PHP, one potential challenge is handling variables that may overlap between the two systems. To solve this issue, you can use namespaces to encapsulate variables within their respective systems, preventing conflicts. 

<?php

namespace CMS {
    $cms_variable = 'CMS Variable';
}

namespace Forum {
    $forum_variable = 'Forum Variable';
}

// Access CMS variable
echo CMS\$cms_variable;

// Access Forum variable
echo Forum\$forum_variable;

?>
