I'm trying to create a user-defined SOAP Webservice using nusoap with the following codes:

service.php

<?php

require 'nusoap/lib/nusoap.php';

require 'fetchdata.php';



$server = new nusoap_server(); 

$server->configureWSDL("Book Info Service","urn:soaptest"); 

$server->register(

    "get_info", 

    array("input"=>"xsd:string"),  

    array("return"=>"xsd:string")  

);





$server->service(file_get_contents("php://input"));



?>

fetchdata.php

<?php



function get_info($input)

{

    $books = [

        "9780435910105"=>["Opening Spaces: An Anthology of Contemporary African Women's Writing","Yvonne Vera","Heinemann"],

        "9780394721170"=>["African Folktales","Roger D. Abrahams","Knopf Doubleday Publishing Group"],

        "9781558615007"=>["Women Writing Africa: West Africa and the Sahel","Esi Sutherland-Addy","Feminist Press at CUNY"]

    ];

    

    foreach($books as $isbn=>$info)

    {

        if($isbn==$input)

        {

            return "<b>Title:</b> ".$info[0]."<br /><br /><b>Author:</b> ".$info[1]."<br /><br /><b>Publisher:</b> ".$info[2];

            break;

        }

                                    

    }

        return "No information found for"." ".$input;        

}



?>

When I run it locally, the WSDL page throws an error and the rest of the page is blank

This page contains the following errors:

error on line 2 at column 1: Extra content at the end of the document

Below is a rendering of the page up to the first error.

Why is this happening?
I want to integrate this into an app so I need the WSDL link.

I honestly just copied and modified this so I don't really know what is happening.
Can anyone help? Thank you.

My Answer:
php
require_once('lib/nusoap.php');

$server = new soap_server();
$server->configureWSDL('UserWebService', 'urn:UserWebService');

$server->register('getUserInfo',
array('username' => 'xsd:string'),
array('return' => 'xsd:string'),
'urn:UserWebService',
'urn:UserWebService#getUserInfo',
'rpc',
'encoded',
'Get user information by username');

function getUserInfo($username) {
// Code to fetch user information from database
return "User information for ".$username;
}

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>


_client.php_

php
require_once('lib/nusoap.php');

$client = new soapclient('http://localhost/service.php?wsdl', true);

$username = 'john_doe';
$response = $client->call('getUserInfo', array('username' => $username));

echo $response;
?>


Make sure that you have the `nusoap.php` file in the `lib` directory and that your server is running PHP with SOAP extension enabled. Also, ensure that the WSDL file is accessible at `http://localhost/service.php?wsdl`.
