PHP/Soap not possible to return a complex type or array??

burdeen

I've been trying to return an array with PHP5 soap. Is this not
supported? or am i doing it wrong? Seems to return on the last element
in the array. In my WSDL i've defined my return type as a complex
type:

<s:complexContent><s:restriction base="SOAP-ENC:Array"><s:attribute
ref="SOAP-ENC:arrayType"
wsdl:arrayType="xsd:string[]"/></s:complexContent>

Actual Output :

object(stdClass)#2 (1) { ["item"]=> object(stdClass)#3 (2) {
["key"]=> string(1) "c" ["value"]=> string(1) "3" } }

Expected:

"a" => "1" and "b" => "2" elements are missing, but "c" => "3" is
there.

Client.php ===
<?php
$client = new SoapClient("http://localhost:84/server.wsdl");
$test = $client->getList();
print(var_dump($test));
?>

Server.php ====
<?php
function getList() {
return array("a" => 1,"b" => 2,"c" => 3); // the array we're
returning
}
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$server = new SoapServer("server.wsdl");
$server->addFunction("getList");
$server->handle();
?>

server.wsdl ===

I've been trying to return an array with PHP5 soap. Is this not

in the array. In my WSDL i've defined my return type as a complex
type:

So, I've solved my own problem... I believe it was the fault of the
WSDL, maybe PHP/Soap is sensitive to my weird namespaces. The thing
that helped the most was the PHP/Soap unit tests; i was able to write
a wsdl that was able to get the results i wanted. take a look here:
http://cvs.php.net/pecl/soap/tests/schema

Hopefully this will help someone else. There is very little (or no?)
documents yet on how to return complex types from the server... so
here is an example. Server will return an array of strings to the
client as SOAP-ENC:arrayType string[].
client2.php ===

<?php
$client = new SoapClient("http://localhost:84/server2.wsdl",
array("trace"=>1,"exceptions"=>1));
$test = $client->test();
var_dump($test);
?>
server2.php ===

<?php

function test() {
return array("ham","cheese","bacon");
}

ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$server = new SoapServer("server2.wsdl");
$server->addFunction("test");
$server->handle();

?>

Good research, perhaps you could add an example to the
http://www.php.net/soap documentation page.
