1. where和whereor并用（闭包方式）

查询id = 1,并且user1 = ‘a’ or user2 = ‘a’

Model::where([
         ['id', '=', 1],
     ])
     ->where(function ($query) {
         $query->whereOr([
             ['user1', '=', 'a'],
             ['user2', '=', 'a']
         ]);
     })->select();

原生sql：

SELECT * FROM `mosel` WHERE  `id` = 1  AND (  `user1` = 'a'  OR `user2` = 'a' )

2.普通单一字段or

$where = [
     'status' => [ [ 'eq' , 1] , [ 'eq' , 2 ] ,  [ 'eq' , 3 ] , 'or'] ,
];
