本文实例为大家分享了php微信公众号开发之快递查询的具体代码，供大家参考，具体内容如下

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;
        $type = $postObj->MsgType;
        $customrevent = $postObj->Event;
        $latitude = $postObj->Location_X;
        $longitude = $postObj->Location_Y;
        $keyword = trim($postObj->Content);
        $time = time();
        $textTpl = "<xml>
              <ToUserName><![CDATA[%s]]></ToUserName>
              <FromUserName><![CDATA[%s]]></FromUserName>
              <CreateTime>%s</CreateTime>
              <MsgType><![CDATA[%s]]></MsgType>
              <Content><![CDATA[%s]]></Content>
              <FuncFlag>0</FuncFlag>
              </xml>";       
        switch ($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 $a)
          {  
            foreach ($a->Time as $b)
            {

                $m.="{$b}{$c}";}
              }
          }
          //遍历获取快递时间和事件
          $contentStr="你的快递单号{$keyword}{$contentStr0}{$m}";
          break;         
        default;
          $contentStr ="此项功能尚未开发";  
        }
