Description:
------------
longs represented as php string variables do not get converted correctly to soap parameter declared as xsd:long. But, longs represented as php numbers work correctly. 

Ex:
$idValue = '572527773301459002' shows up incorrectly as
<ns1:ID>2147483647</ns1:ID>

where as,

$idValue = 572527773301459002 shows up correctly as
<ns1:ID>572527773301459010</ns1:ID>


Reproduce code:
---------------
<?php
$client = new SoapClient(
		"file:///C:/temp/phpbug/MyService.wsdl",
	array( 	"trace" => true,
			"exceptions" => true,
			"location" => "http://localhost:8144/MyService",
			"connection_timeout"=>10)
);
$idValue = '572527773301459002';
$obj = array(
	'ID' => $idValue,
	);
$retObj = $client->__soapCall(
		'operation',
		array( $obj )
	);
?>
