getting data from server in xml format - php

Question

I am trying to call a web service through php . I am sending an XML request for which I am supposed to get back an Xml response. But I as response I am getting only the data without the xml tags. I want it in proper xml format. I also have the wsdl file of the website. If anyone can advise what to do it will be of real help. Thanks in advance for your time.
<?php
$soapUrl=some url';
$xml_post_string='<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sec="http://schemas.xmlsoap.org/ws/2002/04/secext" xmlns:urn="urn:ebx-schemas:dataservices_1.0">
<soapenv:Header>
<sec:Security>
<UsernameToken>
<Username>Some Value</Username>
<Password>Some Value</Password>
</UsernameToken>
</sec:Security>
</soapenv:Header>
<soapenv:Body>
<urn:select_ProductDetail>
<branch>Product</branch>

</soapenv:Body>
</soapenv:Envelope>';
$headers = array(
"Content-Type: text/xml;charset=UTF-8",
"Accept: gzip,deflate",
"Cache-Control: no-cache",
"Pragma: no-cache",
"SOAPAction: \"select\"",
"Host: Host name",
"Connection: Keep-Alive",
"Content-length: ".strlen($xml_post_string),
);
// PHP cURL for https connection with auth
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $soapUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_TIMEOUT, 500);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 500);
curl_setopt($ch, CURLOPT_MAXREDIRS, 12);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$ss = curl_getinfo($ch);
$response = curl_exec($ch);
print_r($response);
exit;
curl_close($ch);
?>

Answer 1

Try modifying your codes to below, for viewing it in BROWSERS
$ss = curl_getinfo($ch);
$response = curl_exec($ch);
echo '<pre>';
echo htmlspecialchars(print_r($response, true));
echo '</pre>';
#print_r($response);
exit;
curl_close($ch);

Answer 2

You are not getting output in xml format because output is getting concatenated with header of curl to avoid so use below code
// PHP cURL for https connection with auth
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $soapUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_TIMEOUT, 500);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 500);
curl_setopt($ch, CURLOPT_MAXREDIRS, 12);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$ss = curl_getinfo($ch);
//$response will give you xml format code
$response = curl_exec($ch);
//$xml will create array from that xml format code
$xml=simplexml_load_string($response);
print_r($xml);
exit;
curl_close($ch);
