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>"; } }
