    $s = new nusoap_client($wsdl,true);

    $param = array('date' => '21-Feb-2012', 'type' => 'DATE');


    $var = $s->call('GetDataFromServices', array('parameters' => $param['date'],$param['type']));

Solution 1

I don't know nusoap, but from the error message, I'd say that $s->call( ... is returning a boolean, probably indicating success or failure of the call. What does your print_r($var) output? (Or it might be like a number of native PHP functions, which return false on failure or else an array or string or whatever on success. Also, check the second argument to the $s->call. It doesn't look quite right, but as I said, I don't know nusoap.

Cheers,
Peter

I suggest you read the nusoap documentation or ask on their users forum (they do have one, don't they?) Again, what does the print_r($var) say?

its just for checking, that whether its a string or array of string.Actually after consuming the server returns me xmlElement and I don't know how to retrieve it. I did lot of R&D but failed. In .net there are ready made classes but in php nothing. I will try again whatever you told me, I will follow that. Thanks again.
