如何在laravel中获取列值的平均值
问题描述：
让我说我有此专栏
star

1
2
5
3
它有7行，并且有整数值！我想添加它并除以其中的行.
It has seven rows and there are integer values! I want to have it added and divided by the rows there are.
我如何在laravel中做到这一点.我可以用普通的php来做，但是我想在laravel中学习.
How do I do it in laravel. I can do it in plain php but I want to learn it in laravel.

尝试一下:
$avgStar = Model::avg('star');
型号"将替换为您的型号名称
" Model " will replace with your model name
