How to convert SOAP response to PHP Array?

Question

I am unable to convert SOAP response to Array in php.

here is the code

 $response = $client->__doRequest($xmlRequest,$location,$action,1);

here is the SOAP response.

<soap:envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:body>
<searchflightavailability33response xmlns="http://FpwebBox.Fareportal.com/Gateway.asmx">
<searchflightavailability33result>
    &lt;Fareportal&gt;&lt;FpSearch_AirLowFaresRS&gt;&lt;CntKey&gt;1777f5a7-7824-46ce-a0f8-33d5e6e96816&lt;/CntKey&gt;&lt;Currency CurrencyCode="USD"/&gt;&lt;OriginDestinationOptions&gt;&lt;OutBoundOptions&gt;&lt;OutBoundOption segmentid="9W7008V21Feb14"&gt;&lt;FlightSegment etc....
    </searchflightavailability33result>
</searchflightavailability33response>
</soap:body>
</soap:envelope>;

i used the following ways to convert to Array,but i am getting empty output.

1.echo '<pre>';print_r($client__getLastResponse());
2.echo '<pre>';print_r($response->envelope->body->searchflightavailability33response);
3.echo '<pre>';print_r($client->SearchFlightAvailability33($response));
     4.simplexml_load_string($response,NULL,NULL,"http://schemas.xmlsoap.org/soap/envelope/");  

5.echo '<pre>';print_r($client->SearchFlightAvailability33($response));

please advice me.

Answer 1

finally i found the solution is

we can get body of the response from SOAP the following ways

example1:

$xml = new SimpleXMLElement($soapResponse);
foreach($xml->xpath('//soap:body') as $header) {
    $output = $header->registerXPathNamespace('default', 'http://FpwebBox.Fareportal.com/Gateway.asmx');    
}

example2:

$doc = new DOMDocument('1.0', 'utf-8');
    $doc->loadXML( $soapResponse );
    $XMLresults     = $doc->getElementsByTagName("SearchFlightAvailability33Response");
    $output = $XMLresults->item(0)->nodeValue;

Answer 2

I found a perfect solution to parse SOAP response to an Array :

$plainXML = mungXML($soapXML);
$arrayResult = json_decode(json_encode(SimpleXML_Load_String($plainXML, 'SimpleXMLElement', LIBXML_NOCDATA)), true);


// FUNCTION TO MUNG THE XML SO WE DO NOT HAVE TO DEAL WITH NAMESPACE
function mungXML($xml)
{
    $obj = SimpleXML_Load_String($xml);
    if ($obj === FALSE) return $xml;

    // GET NAMESPACES, IF ANY
    $nss = $obj->getNamespaces(TRUE);
    if (empty($nss)) return $xml;

    // CHANGE ns: INTO ns_
    $nsm = array_keys($nss);
    foreach ($nsm as $key)
    {
        // A REGULAR EXPRESSION TO MUNG THE XML
        $rgx
        = '#'               // REGEX DELIMITER
        . '('               // GROUP PATTERN 1
        . '\<'              // LOCATE A LEFT WICKET
        . '/?'              // MAYBE FOLLOWED BY A SLASH
        . preg_quote($key)  // THE NAMESPACE
        . ')'               // END GROUP PATTERN
        . '('               // GROUP PATTERN 2
        . ':{1}'            // A COLON (EXACTLY ONE)
        . ')'               // END GROUP PATTERN
        . '#'               // REGEX DELIMITER
        ;
        // INSERT THE UNDERSCORE INTO THE TAG NAME
        $rep
        = '$1'          // BACKREFERENCE TO GROUP 1
        . '_'           // LITERAL UNDERSCORE IN PLACE OF GROUP 2
        ;
        // PERFORM THE REPLACEMENT
        $xml =  preg_replace($rgx, $rep, $xml);
    }
    return $xml;
}

print_r($arrayResult);

It will give you a perfect array of SOAP XML Data.

Answer 3

The following SOAP response structure can be easily converted in an array using a combination of the previous methods. Using only the the function "simplexml_load_string" removing the colon ":" it returned null in some cases.

SOAP Response

<S:Envelope
    xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <ns2:transaccionResponse
            xmlns:ns2="http://ws.iatai.com/">
            <respuestaTransaccion>
                <idTransaccion>94567</idTransaccion>
                <referencia>3958</referencia>
                <idEstado>3</idEstado>
                <nombreEstado>Declinada</nombreEstado>
                <codigoRespuesta>202</codigoRespuesta>
                <valor>93815.0</valor>
                <iva>86815.0</iva>
                <baseDevolucion>0.0</baseDevolucion>
                <isoMoneda>COP</isoMoneda>
                <fechaProcesamiento>24-07-2015 12:18:40 PM</fechaProcesamiento>
                <mensaje>REJECT</mensaje>
                <tarjetaRespuesta>
                    <idFranquicia>1</idFranquicia>
                    <nombreFranquicia>VISA</nombreFranquicia>
                    <numeroBin>411111</numeroBin>
                    <numeroProducto>1111</numeroProducto>
                </tarjetaRespuesta>
                <procesadorRespuesta>
                    <idProcesador>3</idProcesador>
                </procesadorRespuesta>
            </respuestaTransaccion>
        </ns2:transaccionResponse>
    </S:Body>
</S:Envelope>

PHP conversion:

$response = preg_replace("/(<\/?)(\w+):([^>]*>)/", "$1$2$3", $response);
$xml = new SimpleXMLElement($response);
$body = $xml->xpath('//SBody')[0];
$array = json_decode(json_encode((array)$body), TRUE); 
print_r($array);

Result:

Array
(
    [ns2transaccionResponse] => Array
        (
            [respuestaTransaccion] => Array
                (
                    [idTransaccion] => 94567
                    [referencia] => 3958
                    [idEstado] => 3
                    [nombreEstado] => Declinada
                    [codigoRespuesta] => 202
                    [valor] => 93815.0
                    [iva] => 86815.0
                    [baseDevolucion] => 0.0
                    [isoMoneda] => COP
                    [fechaProcesamiento] => 24-07-2015 12:18:40 PM
                    [mensaje] => REJECT
                    [tarjetaRespuesta] => Array
                        (
                            [idFranquicia] => 1
                            [nombreFranquicia] => VISA
                            [numeroBin] => 411111
                            [numeroProducto] => 1111
                        )

                    [procesadorRespuesta] => Array
                        (
                            [idProcesador] => 3
                        )

                )

        )

Answer 4

Php parse SOAP response to an array

 $xml = file_get_contents($response);

// SimpleXML seems to have problems with the colon ":" in the <xxx:yyy> response tags, so take them out
$xml = preg_replace(“/(<\/?)(\w+):([^>]*>)/”, “$1$2$3″, $xml);
$xml = simplexml_load_string($xml);
$json = json_encode($xml);
$responseArray = json_decode($json,true);

Answer 5

I got a single value using DOMDocument.

    $soap_response = $client->__getLastResponse();

    $dom_result = new DOMDocument;
    if (!$dom_result->loadXML($soap_response))
        throw new Exception(_('Error parsing response'), 11);

    $my_val = $dom_result->getElementsByTagName('my_node')->item(0)->nodeValue;

Answer 6

The second answer from @gtrujillos worked for me but with some changes, because the json string needs more formatting code in my case and the xPath needs to be in this way "//S:Body". This is the code that finally solve my problem. I toke the same SOAP Response example and the code for getting and returning a Soap response I found it here:

PHP convertion

//getting the Soap Response
header("Content-Type: text/xml\r\n");
ob_start();

$capturedData = fopen('php://input', 'rb');
$content = fread($capturedData, 5000);
fclose($capturedData);
ob_end_clean();

//getting the SimpleXMLElement object
$xml = new SimpleXMLElement($content);
$body = $xml->xpath('//S:Body')[0];

//transform to json
$json = json_encode((array)$body);

//Formatting the JSON
$json = str_replace(array("\n","\r","?"),"",$Json);
$json = preg_replace('/([{,]+)(\s*)([^"]+?)\s*:/','$1"$3":',$json);
$Json = preg_replace('/(,)\s*}$/','}',$json);

//Getting the array
$array=json_decode($Json,true);

//whatever yo need to do with the array ...

//Return a Soap Response
$returnedMsg=true;//this will depend of what do you need to return
print '<?xml version="1.0" encoding="UTF-8"?>
     <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
     <soapenv:Body>
     <notifications xmlns="http://soap.sforce.com/2005/09/outbound">
     <Ack>' . $returnedMsg . '</Ack>
     </notifications>
     </soapenv:Body>
     </soapenv:Envelope>';
