How to convert SOAP response to PHP Array?

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                        )                )        ))

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

$plainXML = mungXML( trim($soapXML) );$arrayResult = json_decode(json_encode(SimpleXML_Load_String($plainXML, 'SimpleXMLElement', LIBXML_NOCDATA)), true);print_r($arrayResult);// FUNCTION TO MUNG THE XML SO WE DO NOT HAVE TO DEAL WITH NAMESPACEfunction mungXML($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;} // End :: mungXML()

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

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;
