Client server application in nuSOAP - php

Question

I am new to the programming area and this is my first nusoap-0.9.5 client and server program. Although the the server looks correct the client keeps giving me this warning:
PHP Fatal error: SoapClient::SoapClient(): Invalid parameters in /var/www/client.php on line 5
PHP Fatal error: Uncaught SoapFault exception: [Client] SoapClient::SoapClient(): Invalid parameters in /var/www/client.php:5
Stack trace:
#0 /var/www/client.php(5): SoapClient->SoapClient('http://localhos...', true)
#1 {main}
thrown in /var/www/client.php on line 5
Anybody knows the reason? I am trying to find a solution over the net more than a week now and I can not understand what is wrong with my program why it is not working.
Client code:
Thanks again Davey, I have read all the tutorials that you recommend and I am still a bit confused but at least less confused than before. I have modified my code again, I hope it makes more sense now. So here it is:
<?php
include "conf_client.php";
require_once('nusoap.php');
$client = new soapclient('http://localhost:8048/server.php?wsdl',true);
class Data {
public $acro = acro;
public $note = note;
public $prio = prio;
public $date = date;
public function Delete() {
$create = array ($acro,
$date,
$note,
$prio);
return $create;
}// End of Function Delete
}// End of class Data
$data = new Data();
$delete = $data->Delete();
$response = $client->call('Lists.DeleteToDo',$delete);
var_dump($response);
?>
directory: {file:///var/www/server.php}
Any help is much appreciated.
'List.DeleteToDo'
Is the class: List and the Function: DeleteToDo on the side of the server that I am calling.

I manage to find more about my problem and I have solved it. I am posting my server code here maybe it can help also someone else.
As a beginner I have simplified the code as much as possible. I am not including to my answer the configuration file, but if anybody needs it please let me know and I will post it as well.
I would also like to say thank you to everyone who answered my query at this forum and help me understand my errors.
<?php
include "conf.php";
require_once('nusoap/lib/nusoap.php');
$server = new soap_server();

Your URL for the SOAP is trying to access a local file path rather than a URL
If you open the URL you've specified in a browser you should get back a (possibly large) chunk of XML. I can almost guarantee that you would get nothing apart from a 404 error
For the SOAP connection you have to use the URL specified by the webserver rather than a local file path (unless you replace http:// with file:/// - that may work).
If your webserver exposes a URL (e.g., http://localmachine) and the WSDL is hosted in a subfolder (e.g., soapstuff) then the URL you would need to enter into the $client=new soapclient line would be something like http://localmachine/soapstuff?wsdl
