json array to xml convertion issues

[Boniface Mutind]

I have this json data and would like to convert to xml with php..

[themes] => Array
        (
            [theme] => Array
                (
                    [0] => Array
                        (
                            [name] => dasdasd
                            [filename] => dasdasd
                            [isDefault] => 0
                        )

                    [1] => Array
                        (
                            [name] => dasdasd
                            [filename] => dasdasd
                            [isDefault] => 1
                        )

                )

        )

now i want to create an xml in this format..

<themes>
        <theme>
            <name>dasdasd</name>
            <filename>dasdasd</filename>
            <isDefault>0</isDefault>
        </theme>
        <theme>
            <name>dasdasd</name>
            <filename>dasdasd</filename>
            <isDefault>1</isDefault>

        </theme>
</themes>

But when i process with this

// function defination to convert array to xml
    function array_to_xml($template_info, &$xml_template_info) {    

        foreach($template_info as $key => $value) {

            if(is_array($value)) {
                if(!is_numeric($key)){
                    $subnode = $xml_template_info->addChild("$key");
                    array_to_xml($value, $subnode);
                }
                else{
                    array_to_xml($value, $xml_template_info);
                }
            }
            else {
                $xml_template_info->addChild("$key","$value");
            }
        }
    }

    // initializing or creating array
    $template_info =  $templateData;

    // creating object of SimpleXMLElement
    $xml_template_info = new SimpleXMLElement("<?xml version=\"1.0\"?><template></template>");

    // function call to convert array to xml
    array_to_xml($template_info,$xml_template_info);

    //saving generated xml file
    $xml_template_info->asXML(dirname(__FILE__)."/manifest.xml") ;

This is what i get..

<themes>
        <theme>
            <name>dasdasd</name>
            <filename>dasdasd</filename>
            <isDefault>0</isDefault>

            <name>dasdasd</name>
            <filename>dasdasd</filename>
            <isDefault>1</isDefault>

        </theme>
</themes>

How can i fix this? thanks for help.
