How can the structure and parameters of a SOAP function be determined from the WSDL file provided by the EU for retrieving VAT rates in PHP?

To determine the structure and parameters of a SOAP function from a WSDL file provided by the EU for retrieving VAT rates in PHP, you can use the `SoapClient` class in PHP. By passing the WSDL file URL to the `SoapClient` constructor, you can then access the available functions and their parameters using the `__getFunctions()` method. This will give you a list of available SOAP functions along with their input and output parameters. 

$wsdlUrl = "https://example.com/vat_rates.wsdl";
$client = new SoapClient($wsdlUrl);
$functions = $client->__getFunctions();

foreach($functions as $function) {
    echo $function . "\n";
}
