получить данные из файла wsdl это язык различий

У меня есть проект о получении данных из функции wsdl с помощью разницы в vb6.
Я могу получить данные из функции, но это не может не показывать это тайский язык.
данные отображаются «???»

мой код

server.php

<?php
require_once("lib/nusoap.php");
$server = new soap_server();
//$server->configureWSDL("Testing WSDL ","urn:Testing WSDL ");
$server->configureWSDL("GetInformation","urn:GetInformation");
//Create a complex type

//----------------------------------
//Add ComplexType with Array
$server->wsdl->addComplexType("ArrayOfString",
"complexType",
"array",
"",
"SOAP-ENC:Array",
array(),
array(array("ref"=>"SOAP-  ENC:arrayType","wsdl:arrayType"=>"xsd:string[]")),
"xsd:string");
//----------------------------------

$server->register('getInfo',array('CASE_ID' =>    'xsd:string'),array('return' => 'tns:ArrayOfString'),'urn:Info','urn:Info#getInfo');

function getInfo($case_id) {

include("ConnectSQL.php");

$dbhandle = mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
or die("Couldn't open database $myDB");

$strCase_ID = $case_id;
// Query
$qry = "SELECT * ";
$qry .= "FROM tbCustomer WHERE CASE_ID = '$strCase_ID' ";
//$arr[0]= $qry;
//execute the SQL query and return records
$result = mssql_query($qry);
//$arr[0] = $strCase_ID;
$i = 0;
$recordcount = mssql_num_rows($result);
if ($recordcount != 0)
{

//display the results
while($row = mssql_fetch_array($result))
{

$myname = $row["PREFIX"] ." ". $row["NAME"] ." ".  $row["MIDDLE"]." " ;

$arr[$i] =  $myname;


$i = $i+1;

}
//close the connection
mssql_close($dbhandle);
//return $myname; //iconv("ISO-8859-1", "UTF-8", $myname );
return $arr;
}
else
{
return $arr;
//echo "<font color=red>**</font> Username & Password is wrong";
}


}

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