Here's a function that will create a CDATA-section around a string coming from SimpleXML.

<?php
function sxml_cdata($path$string){
 
$dom dom_import_simplexml($path);
 
$cdata $dom->ownerDocument->createCDATASection($string);
 
$dom->appendChild($cdata);
}
?>

A common issue seems to be adding javascript to CDATA and the browser throwing a javascript error. To ensure the javascript works use the following code when adding CDATA:

<?php
/**
 * Append Caracter Data to a node and check for a javascript node
 * 
 * @param DOMElement $appendToNode
 * @param string $text
 */
function appendCdata($appendToNode$text
{
    if (
strtolower($appendToNode->nodeName) == 'script') {  // Javascript hack
       
$cm $appendToNode->ownerDocument->createTextNode("\n//");
       
$ct $appendToNode->ownerDocument->createCDATASection("\n" $text "\n//");
       
$appendToNode->appendChild($cm);
       
$appendToNode->appendChild($ct);
    } else { 
// Normal CDATA node
       
$ct $appendToNode->ownerDocument->createCDATASection($text);
       
$appendToNode->appendChild($ct);
    }
}
?>
The result should be:

<script type="text/javascript">
//<![CDATA[
function someJsText() {
   document.write('Some js with <a href="#">HTML</a> content');
}
//]]></script>

If you would like to refer to the documentation for the class of the returned object, see class.domcharacterdata

Here's some code that takes an associative array and prints it asXML() but creates CDATA sections for each string

<?php
class SimpleXMLExtended extends SimpleXMLElement
    public function 
addCData($string){ 
       
$dom dom_import_simplexml($this);
       
$cdata $dom->ownerDocument->createCDATASection($string);
       
$dom->appendChild($cdata);
    } 
}
function 
assocArrayToXML($root_element_name,$ar){
   
$xml = new SimpleXMLExtended("<?xml version=\"1.0\"?><{$root_element_name}></{$root_element_name}>");
   
$f create_function('$f,$c,$a','
            foreach($a as $k=>$v) {
                if(is_array($v)) {
                    if (!is_numeric($k))$ch=$c->addChild($k);
                    else $ch = $c->addChild(substr($c->getName(),0,-1));
                    $f($f,$ch,$v);
                } else {
                    if (is_numeric($v)){ $c->addChild($k, $v);
                    }else{$n = $c->addChild($k); $n->addCData($v);}
                }
            }'
);
   
$f($f,$xml,$ar);
    return 
$xml->asXML();


/* sample */
$result = array("title"=>"CDATA Sample");
$result['items'] = array();
$result['items'][] = array('title'=>'Some string''number' => 1);
$result['items'][] = array('title'=>'Some string''number' => 2);
$result['items'][] = array('title'=>'Some string''number' => 3);

echo 
assocArrayToXML('result',$result);
?>

The is_numeric check could be changed by a more elaborate regular expression to check if the string is actually xml unsafe but this worked for me.
