效果图:
控制器:
//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>";
}
}
