How can the structure of the SOAP request be modified to match the expected format?

The structure of the SOAP request can be modified by ensuring that the XML elements in the request match the expected format defined by the SOAP server. This includes correctly formatting the headers, body, and parameters within the request. By carefully constructing the XML structure according to the server's requirements, the SOAP request can be successfully sent and processed.

// Constructing the SOAP request with the correct structure
$xml_request = '
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com">
    <SOAP-ENV:Header>
        <!-- Header elements here -->
    </SOAP-ENV:Header>
    <SOAP-ENV:Body>
        <ns1:MethodName>
            <param1>value1</param1>
            <param2>value2</param2>
        </ns1:MethodName>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>';

// Initializing SOAP client
$client = new SoapClient("http://example.com/soap.wsdl");

// Sending the SOAP request
$response = $client->__doRequest($xml_request, "http://example.com/soap", "http://schemas.xmlsoap.org/soap/envelope/", SOAP_1_2);
