Ошибка looks like we got no xml document

Добрый день.
Начал разбираться с SOAP,набросал простенький сервис новостей и клиент под него и получил ошибку.

Что есть:
— сервис новостей,находится в папке news (все это крутится на OpenServre`e)
— soap-server,находится в папке news/soap
— wsdl файл news.wsdl,находится в папке news/soap
— soap-client,находится в папке localhost

Что я делаю:
Запускаю OpenServer,перехожу на localhost — вылетает «Операция Client вернула ошибку: looks like we got no XML document».
Проверил кодировки и BOM-символы,все в порядке.

Исходники:
— soap-server.php

<?php
require "../class/NewsDB.class.php";

	/* Метод возвращает новость по её идентификатору */

					(SELECT name FROM category WHERE category.id=msgs.category) as category, description, source, datetime 
					FROM msgs
					WHERE id = $id";
			$result = $this->_db->query($sql);
			if (!is_object($result)) 
				throw new Exception($this->_db->lastErrorMsg());
			return base64_encode(serialize($this->sqlToArray($result)));
		}catch(Exception $e){
			throw new SoapFault('getNewsById', $e->getMessage());
		}
	}
	/* Метод считает количество всех новостей */
	function getNewsCount(){

Буду признателен за любые идеи и уделенное время.

I’m having some strange problem while using SOAP with PHP.
Same function works with small data, but when my query returns more than X rows, it causes an exception «Uncaught SoapFault exception: [Client] looks like we got no XML document».

This is my code:

<?php
$cliente = new SoapClient(null, array('location' => $myserver,'uri' => 'urn:webservices'));
?>
<select id="actividad" name="actividad" size="1" style="height:40px; width: 100%;">
<?php
$acs = $cliente->get_actividades();
foreach($acs as $actividad) {
echo "<option value='".$actividad['idactividad']."'>".$actividad['descripcion']."</option>";
}                                       
?>
</select>

And this is server side:

public function get_actividades()
{
    $link = new mysqli($this->dbhost,$this->dbuser,$this->dbpass,$this->dbname);
    if (mysqli_connect_errno()) {
        return 0;
    }
    $query = "SELECT idactividad, codigo, descripcion FROM actividades";
    $datos = array();
    if ($stmt = $link->prepare($query)) {
        $stmt->execute();
        $stmt->store_result();
        $datos = $this->fetcharray($stmt);
        $stmt->free_result();
        $stmt->close();
        return $datos;
    } else { 
        return -1; 
    }           
}

That query results in about 37 rows. If I add a «LIMIT» clause to that query between 1 and 21 rows, it works fine, but more than that causes the no-xml-exception.

Can it be some memory problem?? Who could i fix it?

i’m trying to use magento soapV2 to create product, here is the script:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<?php


// Magento login information 
$mage_url = 'http://localhost/first/api/v2_soap?wsdl=1'; 

$mage_user = 'rayapi'; 
$mage_api_key = 'Abcd1234'; 
// Initialize the SOAP client 
$client = new SoapClient( $mage_url ); 

$session = $client->login( $mage_user, $mage_api_key );


$catalogProductCreateEntity = new stdClass();
$additionalAttrs = array();

$catalogProductCreateEntity->name = "product name";
$catalogProductCreateEntity->description = "description";
$catalogProductCreateEntity->short_description = "desc";
$catalogProductCreateEntity->status = "1";
$catalogProductCreateEntity->price = "99";
$catalogProductCreateEntity->tax_class_id = "2";
$catalogProductCreateEntity->websites = array(1,2);
$catalogProductCreateEntity->categories = array(7,15);
$catalogProductCreateEntity->status = 1;
$catalogProductCreateEntity->price = 45;
$catalogProductCreateEntity->tax_class_id = 2;
$catalogProductCreateEntity->weight = 1;

// send the request
$product = $client->catalogProductCreate($session, "simple", 9, 'test_sku', $catalogProductCreateEntity);

// end session and enjoy your updated products :)
$client->endSession($session);

var_dump($product);


?>

Error message:

Fatal error: Uncaught SoapFault exception: [Client] looks like we got no XML document in C:xampphtdocsfirstsoap.php:71 Stack trace: #0 C:xampphtdocsfirstsoap.php(71): SoapClient->__call('catalogProductC...', Array) #1 C:xampphtdocsfirstsoap.php(71): SoapClient->catalogProductCreate('7ab47f189292d99...', 'simple', 9, 'test_sku', Object(stdClass)) #2 {main} thrown in C:xampphtdocsfirstsoap.php on line 71

i tried use
$result = $client->catalogInventoryStockItemList($session, array(‘693’)); // //Products ID
print_r($result);

catalogInventoryStockItemList is work for me but catalogProductCreate not work.

i googled around but their solution not useful to me, how to solve this problem?
