  <para>
   This is a low level API function that is used to make a SOAP call. Usually,
   in WSDL mode, SOAP functions can be called as methods of the
   <classname>SoapClient</classname> object. This method is useful in non-WSDL
   mode when <literal>soapaction</literal> is unknown, <literal>uri</literal>
   differs from the default or when sending and/or receiving SOAP Headers.
  </para>
  <para>
   On error, a call to a SOAP function can cause PHP to throw exceptions or return a
   <classname>SoapFault</classname> object if exceptions are disabled.
   To check if the function call failed to catch the SoapFault exceptions,
   check the result with <function>is_soap_fault</function>.

       An array of the arguments to pass to the function. This can be either
       an ordered or an associative array. Note that most SOAP servers require
       parameter names to be provided, in which case this must be an
       associative array.

   SOAP functions may return one, or multiple values. If only one value is
   returned by the SOAP function, the return value will be a scalar.
   If multiple values are returned, an associative array of named output
   parameters is returned instead.
  </para>
  <para>
   On error, if the <classname>SoapClient</classname> object was constructed
   with the <literal>exceptions</literal> option set to &false;,
   a <classname>SoapFault</classname> object will be returned.
