   //var_dump($data);die;
   $data=array();
   //取出邮箱类型
   foreach($arr as $key=>$v)
   {
    $str=substr($v['email'],strpos($v['email'],"@"),50);
    $str1=substr($str,1);
    $data[$str1][$key]=$str1;
   }
   //var_dump($data);die;
  //获得不同类型邮箱个数
  foreach($data as $key=>$v)

  }*/
  (2种方法)
  $arr=Users::find()->select("email")->column();
  $data=array();
  foreach($arr as $key=>$v)
  {
    $pos=strpos($v,"@");
    $str=substr($v,$pos+1);
    $data[]=$str;
  }
  //var_dump($data);die;
  $count=array_count_values($data);
  // var_dump($count);die;
   foreach($count as $key=>$v)
  {
   echo $key."的邮箱有".$v."个"."<br>";
  }
}
