Description:
------------
When encoding a complex array datatype (via a doc/literal request); the encoding is incorrect.  The following code performs a request, and displays the request/response structures.  The server is unable to locate the client supplied params, due to the request being (I believe) incorrect.

Additionally, PHP appears to not be sending over array element 0 in this demo.

Reproduce code:
---------------
<?php
$WSDL = "http://ws1.api.re2.yahoo.com/ws/soap-demo/full.wsdl";
$DEBUG=true;

$client = new SoapClient( $WSDL, array( "trace" => $DEBUG,
                                        "exceptions" => 0,
                                        ));

function dump_xml( $title, $body )
{
    $nl = preg_replace( "/\>\</", ">\n<", $body );
    $clean = htmlspecialchars( $nl );
    print "\n<b>$title</b>\n<pre>$clean</pre>\n";
}

$r = $client->strArrayReverse('This', 'is', 'a', 'test', '.');
dump_xml( "Request", $client->__getLastRequest() );
dump_xml( "Response", $client->__getLastResponse() );
?>


Expected result:
----------------
The request should be:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:yahoo:platform:soap:demo:full">
<SOAP-ENV:Body>
 <ns1:strArrayReverse>
 <ns1:saVal>
 <param0>This</param0>
<param1>is</param1>
<param2>a</param2>
<param3>test</param3>
<param4>.</param4>
 </ns1:saVal>
 </ns1:strArrayReverse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Note that the method being accessed (strArrayReverse) now contains a single arg (saVal), which is an array of 5 elements.  Also note that param0 is present.

This request will elicit the correct response from the server.

Indent lines indicate lines that have been added, or changed, compared to the original request sent from PHP.

Actual result:
--------------
The request being generated by PHP's soap interface is:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:yahoo:platform:soap:demo:full">
<SOAP-ENV:Body>
<ns1:strArrayReverse/>
<param1>is</param1>
<param2>a</param2>
<param3>test</param3>
<param4>.</param4>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

You should use the folowing call:

$r = $client->strArrayReverse(array('saVal'=>array('This', 'is', 'a', 'test', '.')));

Look into the WSDL.

The "strArrayReverse" method has one parameter of type "full:strArrayReverse", that is a sequence of ONE element named "saVal" of type "stringArray".
