Description:
------------
The Feature SOAP_SINGLE_ELEMENT_ARRAYS has no effect when I try to get a resultset that sometimes contains only one Object. It always removes the array and returns the Object without the array.

See Example Code for additional information and feel free to contact me for additional information.

Reproduce code:
---------------
<?php
$options = array(
    'location' => 'http://u8020.intx.ch.netstream.com/dnssoap/soap.cgi' , 
    'uri' => 'http://dnstool.netstream.com/DnsAPI' , 
    'exceptions' => false , 
    'trace' => false , 
    'soap_version' => SOAP_1_1 , 
    'user_agent' => 'PHP DNS Client' , 
    'features' => SOAP_SINGLE_ELEMENT_ARRAYS
);
$soapserver = new SoapClient(null, $options);

//Watch Param type = A here  --> array 2 results expected here
$result = $soapserver->__soapCall('GetResourceRecords', 
    array(new SoapParam('wtf.com', 'zone') , new SoapParam('A', 'type')
    ));
var_dump($result);

//Watch Param type = MX here --> array with 1 result expected here
$result = $soapserver->__soapCall('GetResourceRecords', 
    array(new SoapParam('wtf.com', 'zone') , new SoapParam('MX', 'type')
    ));
var_dump($result);

?>

Expected result:
----------------
array(2) {
  ["total"]=>
  string(1) "2"
  ["records"]=>
  array(2) {
    [0]=>
    object(stdClass)#4 (7) {
      ["name"]=>
      string(4) "test"
      ["class"]=>
      string(2) "IN"
      ["data"]=>
      string(9) "127.0.0.1"
      ["id"]=>
      string(6) "160441"
      ["parameter"]=>
      string(0) ""
      ["ttl"]=>
      string(0) ""
      ["type"]=>
      string(1) "A"
    }
    [1]=>
    object(stdClass)#5 (7) {
      ["name"]=>
      string(4) "test"
      ["class"]=>
      string(2) "IN"
      ["data"]=>
      string(9) "127.0.0.1"
      ["id"]=>
      string(6) "160442"
      ["parameter"]=>
      string(0) ""
      ["ttl"]=>
      string(0) ""
      ["type"]=>
      string(1) "A"
    }
  }
}

array(2) {
  ["total"]=>
  string(1) "2"
  ["records"]=>
  array(1) {
    [0]=>
    object(stdClass)#4 (7) {
      ["name"]=>
      string(4) "stop.bugging.me"
      ["class"]=>
      string(2) "IN"
      ["data"]=>
      string(9) "32"
      ["id"]=>
      string(6) "160443"
      ["parameter"]=>
      string(0) "50"
      ["ttl"]=>
      string(0) "1337"
      ["type"]=>
      string(1) "MX"
    }
  }
}

Actual result:
--------------
array(2) {
  ["total"]=>
  string(1) "2"
  ["records"]=>
  array(2) {
    [0]=>
    object(stdClass)#4 (7) {
      ["name"]=>
      string(4) "test"
      ["class"]=>
      string(2) "IN"
      ["data"]=>
      string(9) "127.0.0.1"
      ["id"]=>
      string(6) "160441"
      ["parameter"]=>
      string(0) ""
      ["ttl"]=>
      string(0) ""
      ["type"]=>
      string(1) "A"
    }
    [1]=>
    object(stdClass)#5 (7) {
      ["name"]=>
      string(4) "test"
      ["class"]=>
      string(2) "IN"
      ["data"]=>
      string(9) "127.0.0.1"
      ["id"]=>
      string(6) "160442"
      ["parameter"]=>
      string(0) ""
      ["ttl"]=>
      string(0) ""
      ["type"]=>
      string(1) "A"
    }
  }
}
array(2) {
  ["total"]=>
  string(1) "1"
  ["records"]=>
  object(stdClass)#6 (7) {
    ["name"]=>
    string(15) "stop.bugging.me"

I've the same problem; but I use WSDL with my SOAP.
 [2009-11-27 13:45 UTC] niek at signet dot nl 
This bug was filed a long time ago, still no replies. Is there going to be some kind of fix for this?

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Same problem here. xsi:type="ns2:Vector" entries are not translated to arrays if there is only one element inside. Example below:



soap client created like so:
============================================================
$client = new soapclient(null, array(
  'location' => $soap_ejb_service_url,
  'uri' => $soap_ejb_service_name,
  'features' => SOAP_SINGLE_ELEMENT_ARRAYS | SOAP_USE_XSI_ARRAY_TYPE,
  'trace' => true)
);
$response = $client->__soapCall($function, $parameters);
============================================================


raw soap response:
============================================================
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<ns1:searchChatroomResponse xmlns:ns1="urn:fusion" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

</return>

    }
  }

Hi all,

I think for people without WSDL, you shouldn't expect SOAP_SINGLE_ELEMENT_ARRAYS to work.

To know it, SoapClient need a XSD saying it could be or not more than one result to decide it must be in array or not.

Just with SOAP answer it is technically impossible to make a difference between an anwser that is just 1 element but could have N and an answer that is known to be only 1.

Exemple :
<body>
<brotherdetail>age: 17</brotherdetail>
</body>

<body>
<brotherdetail>age: 17</brotherdetail>
<brotherdetail>sister : 1</brotherdetail>
</body>

In first case, if you don't have a XSD to say brotherdetail is a type and have rule maxOccurs = unbounded, how do you expect SoapClient will know it could have been more than one detail ?
Of course with second example, SoapClient will now it could be because it'll find more than one so it will naturally make an array...
