Yii2 字段自增

	$number = 1000;
	$field = 'PV';
	$WeiPageId = 2;
	if ($number == 0 || !in_array($field, ['PV', 'UV'])) return false;
	$model = self::find()
	         ->where(['WeiPageId' => $WeiPageId])
	         ->one();
	$model->$field = $model->$field + $number;
	$res = $model->save();

刚用Yii2 写了一段代码，感觉这样做字段的自增也不错
