Is there any way to convert json to xml in PHP?

If you're willing to use the XML Serializer from PEAR, you can convert the JSON to a PHP object and then the PHP object to XML in two easy steps:

include("XML/Serializer.php");function json_to_xml($json) {    $serializer = new XML_Serializer();    $obj = json_decode($json);    if ($serializer->serialize($obj)) {        return $serializer->getSerializedData();    }    else {        return null;    }}

It depends on how exactly you want you XML to look like. I would try a combination of json_decode() and the PEAR::XML_Serializer (more info and examples on sitepoint.com).

require_once 'XML/Serializer.php';$data = json_decode($json, true)// An array of serializer options$serializer_options = array (  'addDecl' => TRUE,  'encoding' => 'ISO-8859-1',  'indent' => '  ',  'rootName' => 'json',  'mode' => 'simplexml'); $Serializer = &new XML_Serializer($serializer_options);$status = $Serializer->serialize($data);if (PEAR::isError($status)) die($status->getMessage());echo '<pre>';echo htmlspecialchars($Serializer->getSerializedData());echo '</pre>';

(Untested code - but you get the idea)

Crack open the JSON with json_decode, and traverse it to generate whatever XML you want.

In case you're wondering, there is no canonical mapping between JSON and XML, so you have to write the XML-generation code yourself, based on the needs of your application.
