How to create optional parameters in Soapserver

I’m using the native class of PHP to create a Soap server.

Example:

class Bar {

   public function getDrink($age, $money, $name) {
      if ($age >= 18 && $money == 5):
         $drink = "Heineken";
      else:
         $drink = "water";
      endif;
      if (empty($name)): // name é um parametro opcional.
         $name = "Hey ";
      endif;
      return $name . " here is your " . $drink;
   }

}

$options = array('uri' => 'http://localhost/webservice');
$server = new SoapServer(NULL, $options);
$server->setClass('Bar');
$server->handle();

Then I can consume all the methods of the class Bar in my Soapclient, however all parameters become mandatory. how I could specify to the server that some parameters of a given method will be optional?

    The send of the arguments is based on the position, could set a default value for the parameters in the method signature.

  • @rray apparently this will be my worst problem, because I will have to force people to enter some value in the parameters to avoid the risk of a value going to another parameter, because as you said they take the position and not the name.

  • I do not know if this is a problem, you are the server so sets the operating rules the client who will consume need only know and follow their rules otherwise it will not achieve the goal.

Specifying in the function that they are optional. This is done by setting a default value for the parameter in the function signature.

class Bar {

   public function getDrink($age, $money, $name = 'Hey') {
      if ($age >= 18 && $money == 5):
         $drink = "Heineken";
      else:
         $drink = "water";
      endif;
      return $name . " here is your " . $drink;
   }

}

$options = array('uri' => 'http://localhost/webservice');
$server = new SoapServer(NULL, $options);
$server->setClass('Bar');
$server->handle();
