What are potential pitfalls when working with CDATA sections in XML files and how can they be addressed in PHP?

Potential pitfalls when working with CDATA sections in XML files include not properly escaping special characters within the CDATA section, leading to invalid XML and potential parsing errors. To address this issue in PHP, you can use the `htmlspecialchars()` function to escape special characters before placing them within the CDATA section. 

$xmlString = '<root><![CDATA[' . htmlspecialchars($content) . ']]></root>';
