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.
