 New Comment:

I get the same problem here, sample code available via email if
requied. Basically: WSDL says data is double, return NaN / INF -> this
annoying error about "violation". Yet the same stuff works with other
languages..

Description:
------------
Bug 39815 (http://bugs.php.net/bug.php?id=39815) reported a
locale-sensitive error in decoding SOAP double values.  The result was a
fix which it seems has broken support for special double values
represented by strings, such as:

INF
-INF
NAN

When a SOAP response sends one of these values (INF in the example
below) with type "double" or "float" in versions 5.2.1 and later, the
result is a SoapFault of "Violation of Encoding rules", when it should
successfully parse the result as a PHP float of value "INF".

This change happened in 5.2.1 in file ext/soap/php_encoding.c. 
Versions 5.2.0 and older correctly produce the "Expected Result" below. 

Reproduce code:
---------------
<?php
if (!$_REQUEST['soap-server']) {
	try {
		$client = new SoapClient(NULL, array(
			"location" => $_SERVER['SCRIPT_URI'] . "?soap-server=1",
			"uri"      => 'urn:TestSOAP',
			"style"    => SOAP_RPC,
			"use"      => SOAP_ENCODED
			));
		$response = $client->__soapCall('test', array());
		var_dump($response->doubleInfinity);
	}
	catch (SoapFault $e) {
		print_r($e);
	}
} else {
	header('Content-Type: text/xml; charset=utf-8');
	?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><testResponse
xmlns="urn:TestSOAP"><s-gensym3><doubleInfinity
xsi:type="xsd:double">INF</doubleInfinity></s-gensym3></testResponse></soap:Body></soap:Envelope><?php
}
?>

Expected result:
----------------
float(INF)

Actual result:
--------------
SoapFault Object
(
    [message:protected] => SOAP-ERROR: Encoding: Violation of encoding
rules
...
    [faultstring] => SOAP-ERROR: Encoding: Violation of encoding rules
    [faultcode] => Client
    [faultcodens] => http://schemas.xmlsoap.org/soap/envelope/
)
