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 $b)
            {
              foreach ($a->content as $c)
              {
                $m.="{$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";  
        }
