How Yii counts the number of different types of mailboxes

The example in this article describes how Yii counts the number of different types of mailboxes. Share it with everyone for your reference, the details are as follows:

Rendering:

Controller:

//查询邮箱
public function actionEmail()
{
   /* //查询所有邮箱数据（1种）
   $arr=Users::find("select * from users")->asArray()->all();
   //var_dump($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)
  {
   echo $key."的邮箱有".count($v)."个"."<br>";
  }*/
  (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>";
  }
}
