Can nusoap return array of string? - web-services

Question

I would like to return an array of string in my web services
I've tryed :
<?php
require_once('nusoap/nusoap.php');
$server = new soap_server();
$server->configureWSDL('NewsService', 'urn:NewsService');
$server->register('GetAllNews',
array(),
array('return' => 'xsd:string[]'),
'urn:NewsService',
'urn:NewsService#GetAllNews',
'rpc',
'literal',
''
);
// Define the method as a PHP function
function GetAllNews()
{
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
return $stack;
}
but it doesn't work. What is the correct syntax for that ?
Thanks in advance for any help

Answer 1

You first need to define a new type that describes an array of strings like so:
$server->wsdl->addComplexType(
'ArrayOfString',
'complexType',
'array',
'sequence',
'',
array(
'itemName' => array(
'name' => 'itemName',
'type' => 'xsd:string',
'minOccurs' => '0',
'maxOccurs' => 'unbounded'
)
)
);
Then you can use tns:ArrayOfString as the return type.

This site describes a nice way to return complex datatypes and receive it with C#: http://sanity-free.org/125/php_webservices_and_csharp_dotnet_soap_clients.html

When returning array of arrays, you might need a different configuration from Oliver. For example phfunc2php uses this technique in the nusoapcode.class.php file (https://github.com/sylnsr/pgfunc2php/blob/master/nusoapcode.class.php). The code it generates looks like so:
$server->wsdl->addComplexType(
'ArrayOfArrays','complexType','array','',
'SOAP-ENC:Array',
array(),
array(array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'xsd:string[]')));
and then the functions simply needs to return "tnsArrayOfArrays:
$server->register(
'sel_signon_id_by_uuid',
array('user_uuid' => 'xsd:string'),
array('return'=>'tns:ArrayOfArrays'),
The project mentioned above can compile working code for you, should you want to see this.
