How can I solve "XML error parsing SOAP payload on line 1: Invalid document end" in PHP Nusoap

Question

I am just new to PHP Nusoap and I tried to run my program and I am getting this kind of error when I print_r($client). Here is the error :

Error: XML error parsing SOAP payload on line 1: Invalid document end

for my code :

webservice_server.php

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

$server = new soap_server();

$server->configureWSDL('Database Data Insertion', 'urn:Insert');
//$server->soap_defencoding = 'utf-8';
$server->register('InsertData',
    array(
        'data' => 'xsd:data',       
        'data1' => 'xsd:data1',
        'data2'  => 'xsd:data2',
        'data3'  => 'xsd:data3',
        'data4' => 'xsd:data4',
    ),
    array(
        'return' => 'xsd:string'        
    ),
    'urn:Insert',
    'urn:Insertwsdl#InsertData',
    'rpc',
    'literal',
    'Retrieve data from  the database'
    );

    function InsertData($data, $data1, $data2, $data3, $data4){

        $db_host = '127.0.0.1';
        $db_username = 'sample';
        $db_password = '' ;
        $db_name = 'sample';

        $conn = new mysqli($db_host, $db_username, $db_password, $db_name);

        if ($conn->connect_error) {
            trigger_error('Database connection failed: ', $conn->connect_error, E_USER_ERROR);
        }

        $sql = "SELECT * FROM sample_transaction ";

        $query = $conn->query($sql);

        if ($query->num_rows > 0) {
            while ($row = $query->fetch_assoc()) {
                echo "<br /> Data : " .$row['data'];
                echo "<br /> Data1 : " .$row['data1'];
                echo "<br /> Data2 : "  .$row['data2'];
            }

        } else {
            echo "0 Results";
        }
    }

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

webservice_client.php

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

$data = json_decode(file_get_contents("php://input"), true);


$data = $data['data'];
$data1 = $data['data1'];
$data2 = $data['data2'];
$data3= $data['data3'];
$data4 = $data['data4'];
$client = new nusoap_client('http://sampleserver:8544/Nusoap/webservice_server.php?wsdl', true);

$datas = array(
     'data' => $data,
    'data1' => $data1,
    'data2'=> $data2,
    'data3' => $data3,
    'data4' => $data4,  
    );

$result= $client->call('InsertData', $datas);

print_r($result);

echo "<br /><pre>" .$client. "</pre>";
echo "<h2>Request</h2>";
echo "<pre>" .htmlspecialchars($client->request, ENT_QUOTES). "</pre>";
echo "<h2>Response</h2>";
echo "<pre>" .htmlspecialchars($client->response, ENT_QUOTES). "</pre>";
?>

I just comment out the $server->soap_defencoding because the response will have a content-type like text/xml charset=utf-8 if not comment out. Is it also a problem if I don't have the same content-type, the charset I mean? Base on the codes I posted above how can I solve this issue because I been looking for solution for this in 2 days. Can someone point out where did I go wrong and how can I solve this? By the way, the code will just select from the database, it retrieves only few data from the database and got that error. Any help is appreciated. Thanks a lot.

Answer 1

Please keep

$server->soap_defencoding = 'utf-8';

add

$client->soap_defencoding = 'utf-8'; 
$client->encode_utf8 = false;
$client->decode_utf8 = false;

if error continues, please add

$server->encode_utf8 = false;
$server->decode_utf8 = false;

to the server file
