快递查询

数组用法
foreach

查询接口是：爱快递：https://www.aikuaidi.cn/api/

核心代码如下：

$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
        $fromUsername = $postObj- FromUserName;
        $toUsername = $postObj- ToUserName;

        $customrevent = $postObj- Event;
        $latitude = $postObj- Location_X;
        $longitude = $postObj- Location_Y;
        $keyword = trim($postObj- Content);
        $time = time();
        $textTpl = "<xml 
              <ToUserName <![CDATA[%s]] </ToUserName

              </xml ";       
        switch ($type)
        { 
        case "text";
          $status=array('0'= '查询出错','1'= '暂无记录','2'= '在途中','3'= '派送中','4'= '已签收','5'= '拒收','6'= '疑难件','7'= '退回');//构建快递状态数组
          $kuaidiurl="http://www.aikuaidi.cn/rest/?key=ff4735a30a7a4e5a8637146fd0e7cec9&order={$keyword}&id=shentong&show=xml";//快递地址
          $kuaidistr=file_get_contents($kuaidiurl);//读入文件
          $kuaidiobj=simplexml_load_string($kuaidistr);//xml解析
          $kuaidistatus = $kuaidiobj- Status;//获取快递状态
          $kuaistr=strval($kuaidistatus);//对象转换为字符串
          $contentStr0 =$status[$kuaistr];//根据数组返回
          foreach ($kuaidiobj- Data- Order as $a)
