Description:
------------
I believe that there is a problem with the SOAP client in that it is not correctly parsing parameters that are specified in teh WSDL as xsd:boolean.  The app that I am connecting to requires boolean values of true and false, however PHP soap is translating true to 1 and false to blank/null.

Reproduce code:
---------------
SoapServer.php
<?php
$quotes = array( 
  "ibm" => 99.42 
);   
function getQuote($booltest, $symbol) { 
  global $quotes; 
  return $quotes[$symbol] . " And the boolean value is {$booltest}"; 
} 
ini_set("soap.wsdl_cache_enabled", "0");
$server = new SoapServer("stockquote.wsdl"); 
$server->addFunction("getQuote"); 
$server->handle(); 
?>
SoapClient.php
<?php
 $client = new SoapClient("stockquote.wsdl"); 
  print($client->getQuote(false,"ibm")); 
?>



Expected result:
----------------
NB: You will need to create a WSDL for the above. Use the one from Dmitry Stogov's examples and change:

<message name='getQuoteRequest'> 
  <part name='booltest' type='xsd:boolean'/> 
  <part name='symbol' type='xsd:string'/> 
</message> 
<message name='getQuoteResponse'> 
  <part name='Result' type='xsd:string'/> 
</message> 


Expected result:

99.42 And the boolean value is false

Actual result:
--------------
99.42 And the boolean value is
