DOMDocument::createCDATASection

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>

Here's a function that will create a CDATA-section around a string coming from SimpleXML.<?phpfunction sxml_cdata($path, $string){  $dom = dom_import_simplexml($path);  $cdata = $dom->ownerDocument->createCDATASection($string);  $dom->appendChild($cdata);}?>

If you would like to refer to the documentation for the class of the returned object, see http://www.php.net/manual/en/class.domcharacterdata.php

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