Flex's HTTPService 数据交互代码大集合
今天把常用的后台代码整理一下，教程就不用写了，我相信要是涉及到这方面的人，应该不用手把手教的，整理的代码主要有ＰＨＰ，ＡＳＰ．ＮＥＴ，ＪＡＶＡ．够爽吧．最近也正在整理ＦＭＳ２.０应用的各种语言版本的例子，以后可能会爆出来．
先分一下类：HTTPService主要分为普通网页格式调用和，ＸＭＬ方式调用．
Flex(普通形式):

XML 例子

$options = get_shipping_options($_REQUEST["zipcode"], $_REQUEST["pounds"]);
$results[] = "<options>";
foreach ($options as $service => $price) {

shipping.php
<?php
