Generate XML using PHP - php

Question

I have the following PHP code from which I need to generate XML.
$hparams["SiteName"]="";
$hparams["AccountCode"]="";
$hparams["UserName"]='xxxx';
$hparams["Password"]='xxxx';
$client_header = new SoapHeader('url','AuthenticationData',$hparams,false);
$cliente = new SoapClient($wsdl); $cliente->__setSoapHeaders(array($client_header));
$opta=array();
$opta["Search"]["request"]["Origin"]="MAA";
$opta["Search"]["request"]["Destination"]="BOM";
$opta["Search"]["request"]["DepartureDate"]="2014-05-20T00:00:00";
$opta["Search"]["request"]["ReturnDate"]="2014-05-22T00:00:00";
$opta["Search"]["request"]["Type"]="OneWay";
$opta["Search"]["request"]["CabinClass"]="All";
$opta["Search"]["request"]["PreferredCarrier"]="";
$opta["Search"]["request"]["AdultCount"]="1";
$opta["Search"]["request"]["ChildCount"]="0";
$opta["Search"]["request"]["InfantCount"]="0";
$opta["Search"]["request"]["SeniorCount"]="0";
$opta["Search"]["request"]["IsDirectFlight"]="true";
$opta["Search"]["request"]["PromotionalPlanType"]="Normal";
$h=array();
$h= (array)$cliente->__call('Search',$opta);
How can I generate an XML of the above variables in PHP ?
The format should be
<xml>
<credential>
<Sitename>sitename</Sitename>
<AccountCode>ACC Code</AccountCode>
</credentials>
<Data>
<Origin>MAA</Origin>
<Destination>BOM</Destination>
</Data>
</xml>
Any help would be appreciate.
Thank you.

<?php
ini_set('error_reporting', E_ALL);
$dom = new DomDocument('1.0'); // making xml
$credentials = $dom->appendChild($dom->createElement('Credentials')); // adding root element <credentials>
$sitename = $credentials->appendChild($dom->createElement('Sitename')); // adding element <sitename> in <credentials>
$accountcode = $credentials->appendChild($dom->createElement('AccountCode')); // adding element <accountcode> in <credentials>
$sitename->appendChild($dom->createTextNode('sitename')); // adding text in <sitename>
$accountcode->appendChild($dom->createTextNode('ACC Code')); // adding text in <accountcode>
$data = $dom->appendChild($dom->createElement('Data'));
$origin = $data->appendChild($dom->createElement('Origin'));
$destination = $data->appendChild($dom->createElement('Destination'));
$origin->appendChild($dom->createTextNode('MAA'));
$destination->appendChild($dom->createTextNode('BOM'));
$dom->formatOutput = true; // generating xml
// generating XML as string or file
$test1 = $dom->saveXML();
$dom->save('test1.xml');
?>
I think you could write loop by yourself ;)
P.S. PHP 5+

First of all, your xml is not well structured.
It should be like:
<xml>
<credentials>
<Sitename>sitename</Sitename>
<AccountCode>ACC Code</AccountCode>
<Data>
<Origin>MAA</Origin>
<Destination>BOM</Destination>
</Data>
</credentials>
<credentials>
...
</credentials>
</xml>
Iterate the obtained result, and by concating , form the needed xml.
