内置Soap扩展php5作为关联数组传入参数

我想把这个xml传递给这个web服务函数

<UserName>myuser</UserName> 
<Password>password</Password> 
<User>
    <AddCoverCode />
    <title>sdadasdsa</title>
</User>
</CreateNewUser>','',array(),'document', 'literal');

---

我希望这不是真正的服务的真正密码。我也有类似的问题。看看我的答案：

array('CreateNewUser' => array(
    'UserName' =>  'sc', 
    'Password' =>  'i82372',
    'Registration' =>   array('username' =>'new','password' =>'ss'));

$client = new SoapClient($url);

$params = array( 'UserName' => 'sc', 'Password' => 'i82372', 'Registration' => array('username' =>'new','password' =>'ss' );

$res = $client->createUser($params);
