How can CDATA elements be used to prevent errors when including HTML code in XML files in PHP?

When including HTML code in XML files in PHP, special characters like "<" and ">" can cause parsing errors. To prevent this, CDATA elements can be used to encapsulate the HTML code, allowing it to be treated as character data rather than markup. This ensures that the HTML code is not misinterpreted by the XML parser. 

$xml = &#039;&lt;?xml version=&quot;1.0&quot;?&gt;
&lt;root&gt;
    &lt;content&gt;&lt;![CDATA[&lt;p&gt;This is some &lt;strong&gt;HTML&lt;/strong&gt; content&lt;/p&gt;]]&gt;&lt;/content&gt;
&lt;/root&gt;&#039;;

$doc = new DOMDocument();
$doc-&gt;loadXML($xml);

echo $doc-&gt;saveXML();
