PHP SOAP server returns array using NuSOAP Library
 
Hi,
I have a function in my SOAP server that returns an array. When the client calls this function, it only receives "array", and when I use foreach to print each member of this array, it tells me that this is not an array. If I change the returned value of the function to a string or integer type everything works fine though, so I don't think that there is any problem with the client.

I am using NuSOAP library on php to achieve that.

I had doubt when declaring the type of return value of the function. In XML schema there is no array type, so I specified the return value as a string like this:

PHP Code:
$server->register("getLocation",
                array('country_population' => 'xsd:string',
                'city_population' => 'xsd:string'),
                array ('return' => 'xsd:string'),
                'urn:world',
                'urn:worldquote#getLocation'); 
The return values is a result of a query from database.

Any idea how I can declare array element in XML schema?

Hi

In the register call, you are saying that your function returns a string. You need to make the type yourself. Something like:

PHP Code:
$server->wsdl->addComplexType("ArrayOfString",
                 "complexType",
                 "array",
                 "",
                 "SOAP-ENC:Array",
                 array(),
                 array(array("ref"=>"SOAP-ENC:arrayType","wsdl:arrayType"=>"xsd:string[]")),
                 "xsd:string"); 
Then, when use something like this for return type:
PHP Code:
array("return" => "tns:ArrayOfString"), 
instead of
PHP Code:
array ('return' => 'xsd:string'), 
Haven't tested it, but I coded something like that before, but I don't have it here now.
