This was 2013 and I actually have exactly the same problem. Well, it 's 2019 and PHP 's current version is 7.3 and 7.4 is coming up to us with big steps. Unfortunately the SoapServer class ignores soap headers completely in a SoapFault case.
I 've written a small workaround to manipulate the XML response of the soap server. For everone who 's having the same issue, here 's a small example, how to solve it.
1. Initialise your Soap Server
$server = new SoapServer($wsdl, $options);
ob_start();
$server->setObject($service);
$server->handle();
$response = ob_get_contents();
ob_end_clean();
Actually we 're doing a simple initialization. Instead of simple returning the content we intercept the xml response with the output buffering functions. The result of the is a xml string in $response
.
2. Find out if the reponse is a fault
Actually the SoapServer
class is adding soap headers, if it was a valid response. We have to find out, if the response is a fault.
$doc = new DOMDocument();
$doc->loadXML($response);
$xpath = new DOMXPath($doc);
$isFault = $xpath->query('//*[local-name()="Fault"]')->length;
Just load the response xml string into the DOMDocument
class. From now on we are able to access xml elements with DOM functions. For better handling I 'm using the DOMXPath
class. Of course it is also possible to determine the XML nodes with the DOMDocument class. The $isFault
variable is useful for the next step.
3. In fault case set a soap header
Unfortunately there is no fancy addSoapHeader
function for simply setting a soap header. We have to do it manually in this case.
if ($isFault) {
$header = $doc->createElementNS('http://schemas.xmlsoap.org/soap/envelope/', 'Header');
$body = $doc->getElementsByTagNameNS('http://schemas.xmlsoap.org/soap/envelope/', 'Body')->item(0);
$realm = $doc->createElementNS('http://soap-authentication.org/basic/2001/10/', 'h:Realm');
$basicChallenge = $doc->createElementNS('http://soap-authentication.org/basic/2001/10/', 'h:BasicChallenge');
$basicChallenge->appendChild($realm);
$header->appendChild($basicChallenge);
$doc->documentElement->insertBefore($header, $body);
}
$xmlResponse = $doc->saveXML($doc->documentElement);
header('Content-Length: ' . strlen($xmlResponse));
echo $xmlResponse;
exit();
In a fault case we create a header element and add all the child nodes we need. If averything was appended insert the header before the body, save the new xml structure in a string and echo it.
Hope this helps a bit.
