Simple: sending XML with PHP

[johnsmith153]

I'm trying to send this:

<?xml version="1.0" encoding="utf-8"?>
<Request version="1.0" xmlns="http://europay.smart2pay.com/message">
<Action>INSERT_PAYIN</Action> <MID>F520156B-5E64-447F-B0B2-C638FA101C6F</MID> <PaymentMethod>mercadopago</PaymentMethod> <IPAddress>127.0.0.1</IPAddress> <Hash>F83525BC77811EC24FF10E50383BB5ED</Hash>
<Details>
 <MTID>123456789</MTID>
 <Amount>100</Amount>
 <Currency>REA</Currency> <SuccessURL>http://www.smart2pay.com/success.html</SuccessURL>    <FailureURL>http://www.smart2pay.com/failure.html</FailureURL> <CancelURL>http://www.smart2pay.com/cancel.html</CancelURL>   <ProcessingURL>http://www.smart2pay.com/processing.html</ProcessingURL> <Shipping Amount="50" CostMode="DS" />
 <Language>pt-BR</Language> <Description>payment</Description>
 <CustomerName FirstName="John" LastName="Doe" /> <CustomerEmail>john.doe@test.com</CustomerEmail>
    </Details>
</Request>

like this:

$client = new SoapClient("https://europaytest.smart2pay.com/MerchantService.asmx?wsdl");
$response = $client->__doRequest($xml, "https://europaytest.smart2pay.com/MerchantService.asmx", "SubmitRequest", 1.1);

...but it just doesn't work saying "Server did not recognize the value of HTTP Header"

Any ideas?

You may need to use the SOAP XML format, rather than the standard XML format
