How does the __soapCall() function in PHP help in resolving issues related to special characters in function names for Soap calls?

When making SOAP calls in PHP, if the function name contains special characters such as a hyphen or a period, it can cause issues with the SOAP client. To resolve this problem, the __soapCall() function in PHP can be used to call SOAP functions with special characters in their names by providing the correct function name as a parameter.

// Example of using __soapCall() to call a SOAP function with a special character in its name
$client = new SoapClient("example.wsdl");

// Call the SOAP function with a special character in its name
$response = $client->__soapCall("function-with-special-character", array($params));
