// This is my solution to swap hash arrays between client/server. The receiver 
// has to rebuild the hash object in the way his programming language supports 
// hash arrays. It's just an example solution. To use the types defined here, 
// you have to include this file in your source using "require". This file has 
// also to be in the list of files that are parsed by PhpWsdl.
//
// A sample unserialized PHP hash array (use the "Serialize" method on this):
//
//  Array(
//      'a' =>  'Value of a',
//      'b' =>  'Value of b'
//  )
//
// The resulting serialized array (return this):
//
//  Array(
//      PhpWsdlHash(
//          'key'   =>  'a',
//          'value' =>  'Value of a'
//      ),
//      PhpWsdlHash(
//          'key'   =>  'b',
//          'value' =>  'Value of b'
//      )
//  )
//
// The received serialized array (use the "Deserialize" method on this):
//
//  Array(
//      object(
//          'key'   =>  'a',
//          'value' =>  'Value of a'
//      ),
//      object(
//          'key'   =>  'b',
//          'value' =>  'Value of b'
//      )
//  )
//
// The value type must be unique within an hash array. You can return prepared 
// types like StringHashArray, or you define your own ones. To serialize an 
// hash array to the target type, use the PhpWsdlHashArrayBuilder class:
//
// return PhpWsdlHashArrayBuilder::Serialize($yourHashVariable);
//
// To deserialize an received object:
//
// $yourHashVariable=PhpWsdlHashArrayBuilder::Deserialize($receivedHashVariable);
//
// Tip: I prefer converting hashes into an INI formatted string. The string 
// type is primitive, but it can contain complex information. In nearly every 
// programming language you can work with the INI format with predefined 
// classes - or it's very easy to write your own.
