Calling a SOAP web service from PHP

The SOAP binding is RPC/encoded, and the WSDL is not published.

Using the PHP SoapClient:

define('NEWLINE', "<br />\n");

// SOAP client

$options = array
(
	'location' => 'https://example.com:1234/sample/service',
	'uri' => 'http://example.com/sample/namespace/data',
	'style' => SOAP_RPC,
	'use' => SOAP_ENCODED,
	'trace' => true // in conjunction with $soapClient->__getLastRequest() below
);
$soapClient = new SoapClient(null, $options);

// SOAP header

$nsHeader = 'http://example.com/sample/namespace/security';
$elementName = 'Security';

$usernameToken->Username = new SoapVar('user9', XSD_STRING, null, null, null, $nsHeader);
$usernameToken->Password = new SoapVar('pass1234', XSD_STRING, null, null, null, $nsHeader);

$content->UsernameToken = new SoapVar($usernameToken, SOAP_ENC_OBJECT, null, null, null, $nsHeader);

$soapHeader = new SoapHeader($nsHeader, $elementName, $content);
$soapHeaders[] = $soapHeader;
$soapClient->__setSoapHeaders($soapHeaders);

// SOAP call

$method = 'getData';
$parameters = array
(
	new SoapParam('abcdef', 'param1'),
	new SoapParam(12345, 'param2')
);

$success = true;
try
{
	$result = $soapClient->__soapCall($method, $parameters);
}
catch (SoapFault $fault)
{
	echo "Fault code: {$fault->faultcode}" . NEWLINE;
	echo "Fault string: {$fault->faultstring}" . NEWLINE;
	$success = false;
}

echo $soapClient->__getLastRequest(); // output the request XML

if ($success)
{
	echo "<pre>\n";
	print_r($result);
	echo "</pre>\n";
}

if ($soapClient != null)
{
	$soapClient = null;
}

Using curl:

define('NEWLINE', "<br />\n");

$ch = curl_init();

$data = '<soapenv:Envelope xmlns:ns2="http://example.com/sample/namespace/security"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns1="http://example.com/sample/namespace/data">
  <soapenv:Header>
    <ns2:Security>
      <ns2:UsernameToken>
        <ns2:Username>user9</ns2:Username>
        <ns2:Password>pass1234</ns2:Password>
      </ns2:UsernameToken>
    </ns2:Security>
  </soapenv:Header>
  <soapenv:Body>
    <ns1:getData soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <param1 xsi:type="xsd:string">abcdef</param1>
      <param2 xsi:type="xsd:integer">12345</param2>
    </ns1:getData>
  </soapenv:Body>
</soapenv:Envelope>';

$fh = fopen('soap_response.txt', 'w'); 

curl_setopt($ch, CURLOPT_URL, 'https://example.com:1234/sample/service');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSLKEY, 'sample.pem');
curl_setopt($ch, CURLOPT_FILE, $fh);

if (curl_exec($ch) === false)
{
    echo "Curl error: " . curl_error($ch) . NEWLINE;
}
else
{
    echo "Operation completed successfully" . NEWLINE;
}

curl_close($ch);
fclose($fh);
