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<?phpfunction 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;}?>?原文链接：http://www.rexsee.com/CN/bbs/thread/2012-04-29/556.html
