NuSoap创建JSON响应

Question

今天，我已经使用“Nusoap”库创建了一个带有SOAP的简单WebServices服务器。当然是XML格式的响应数据。

我的服务器代码：

<?php 
require_once "nusoap.php"; 

function pLogin($username, $password) { 
    if (($username == "admin")&&($password == md5("123456"))) { 
     //return "AAAAAAAAAA Login OK"; 
     return (array("cmd" => "LOGIN","status" => "LOGINOK","fullname" => "John Smith", "phone" => "0987654321", "credit" => "5600", "session" => "ID24324343434")); 
    } 
    else { 
      return "Login Fail"; 
    } 
} 

$server = new soap_server(); 
$server->register("pLogin"); 
$server->service($HTTP_RAW_POST_DATA); 
?> 

而且作为HTTP响应：

<?xml version="1.0" encoding="ISO-8859-1"?> 
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> 
    <SOAP-ENV:Body> 
     <ns1:pLoginResponse xmlns:ns1="http://tempuri.org"> 
      <return> 
       <cmd xsi:type="xsd:string">LOGIN</cmd> 
       <status xsi:type="xsd:string">LOGINOK</status> 
       <fullname xsi:type="xsd:string">John Smith</fullname> 
       <phone xsi:type="xsd:string">0987654321</phone> 
       <credit xsi:type="xsd:string">5600</credit> 
       <session xsi:type="xsd:string">ID24324343434</session> 
      </return> 
     </ns1:pLoginResponse> 
    </SOAP-ENV:Body> 
</SOAP-ENV:Envelope> 

但我想创建JSON格式的响应数据，如或：

HTTP/1.1 200 OK 
.... (HTTP header here) 
Content-Type: text/json 
{"cmd":"LOGIN","status":"LOGINOK","fullname":"John Smith","phone":"0987654321","credit":"5600","session":"ID24324343434"} 

请帮助我修改WebServices服务器中的代码以创建JSON格式的数据。

代替

return (array("cmd" => "LOGIN","status" => "LOGINOK","fullname" => "John Smith", "phone" => "0987654321", "credit" => "5600", "session" => "ID24324343434")); 

写

return json_encode(array("cmd" => "LOGIN","status" => "LOGINOK","fullname" => "John Smith", "phone" => "0987654321", "credit" => "5600", "session" => "ID24324343434"));
