Echo PHP Variable in XML and Post value to webservice - php

Question

I need to publish PHP variable values on SOAP-based web service some how I am not able to convert PHP POST values in XML elements.
How can I get POST variable, say abc, in sName element?
My code in PHP
<?php
//session_start();
$server_name= abc;
$xml_post_string = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<createtest xmlns="http://tempuri.org/">
<sA>ADD</sA>
<sType>service</sType>
<sName>"$server_name"</sName>
</createtest>
</soap:Body>
</soap:Envelope>';
$headers = array(
"Content-Type: text/xml; charset=utf-8",
"Host: http://example.com",
"Content-length: ".strlen($xml_post_string),
"SOAPAction: http://tempuri.org/createtest"
);
url = 'http://example.com'; // WSDL web service url for request
method/function
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP
request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
echo $response = curl_exec($ch);
?>

You have to put quotes around abc, when you define the variable as a string:
$server_name = "abc";
And you could also put the variable in the string like this to make it easier to understand it as a variable in such a long string:
$xml_post_string = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<createtest xmlns="http://tempuri.org/">
<sA>ADD</sA>
<sType>service</sType>
<sName>'.$server_name.'</sName>
</createtest>
</soap:Body>
</soap:Envelope>';
