Using PHP5's SoapClient to recieve a SOAP envelope that contains multiple instances of the same tag, the resulting object retains only the last item of the given tag name.
E.G.  Receiving a SOAP message containing:

Results in an object containing:

[dogs] => stdClass Object
            [dog] => Benji

I'm using a perl SOAP::Lite script for the server, and php5's SOAP for the client.  When the tags are changed to be unique (e.g. <dog1>, <dog2>, <dog3>) all three examples are returned as expected.

Reproduce code:
[ TestFunction is a simple function that returns a SOAP envelope containing: 

$client is the PHP5 SoapClient variable. ]

$test = $client->__call('TestFunction', array($a));

echo '<pre>';
echo '</pre>';

Expected result:
stdClass Object
    [dogs] => array
        [0] => Scooby
        [1] => Lassie
        [2] => Benji

Actual result:
stdClass Object
    [dogs] => stdClass Object
            [dog] => Benji

May be the problem in WSDL file?
Can you put here WSDL file, SOAP request (XML) and SOAP response?

I am experiencing the same problem with the MSN Search API. More specifically on the SourceRequest objects, where there are 4 tags of the same name.

I have the same problem.
I think the problem comes from the fact that, as the SOAP response is stored in associative arrays, when there are 2 (or more) tags with the same name the value of the second tag replace the value of first one.

I have also seen this problem, both in sending and parsing soap requests. I agree that it seems to be because they are internally stored as associative arrays, something which is more obvious to the user when sending requests.

Same problem exists for sending the same element multiple times.
