使用Rexsee、Jquery、PHP开发移动应用中的数据交互问题

Rexsee社区的一篇经验贴，转过来，主要是介绍数据交互这一块的实现，共同学习：

在开发某移动销售产品时，用户要求通过WebService调用进行数据交互。使用Rexsee,Jquery-mobile,PHP,WebService几种开发工具可以做到设备调用完成照片、定位等功能，使用Juqery-mobile开发界面，使用PHP+SOAP完成数据库及Webservice的数据交互功能，通过JSON使用PHP将返回数据封装后再返回到前端，这样就做到了数据的异步交互，而且返回结果标准统一，可用性强。下面通过几个例子介绍一下：

以上页面通过Jquery-mobile显示一个登录页面，点击提交后异步调用func_sap函数完成WebSerivce调用及返回，返回数据以JSON形式，通过javascript的json函数将数据提取并处理。

func_soap.php文件
<?php
function getshop($phone)
{
$wsdl = "http://.../Service.asmx?wsdl";
$soap_client = new SoapClient($wsdl);
$param=array( 'phone'=> $phone); 
$objectresult = $soap_client->AgetShop($param);
$simpleresult = $objectresult->AgetShopResult; 
$obj = simplexml_load_string($simpleresult);
$obj->Shop[0]->addChild("oper", "getshop");
$json = json_encode($obj);
$array = json_decode($json,TRUE); 
$_SESSION['shopno']= $array["Shop"]['shopno'];
$_SESSION['phone']=$phone;
return $json;
}
//调用函数
header("Content-Type:text/html;charset=utf-8");
$moper=$_POST['oper']; 
if ($moper=="getshop")
{
$mresult=getshop($muname);
echo $mresult;
}
?>
