tp5的条件搜索 where和whereor复杂用法

实例1:不需要传参数

     $room_qualification_count=Db::name("room")  ->where("level",1)  ->where(function ($room_qualification_count)   {
            $room_qualification_count->whereOr("a",0);
            $room_qualification_count->whereOr("b",0);
            $room_qualification_count->whereOr("c",0);
            $room_qualification_count->whereOr("d",0);
        })->fetchSql(true)  ->find();
        
var_dump($room_qualification_count);die;

SELECT 
* 
FROM
 `fa_room` 
WHERE  `level` = '1'  
AND (  `a` = 0  OR `b` = 0  OR `c` = 0  OR `d` = 0 ) 
LIMIT 1

实例2：需要传参

     $whereO=1;
             $room_qualification_count=Db::name("room")  ->where("level",1)  ->where(function ($room_qualification_count)  use ($whereO) {
                    $room_qualification_count->whereOr("a",$whereO);
                    $room_qualification_count->whereOr("b",0);
                    $room_qualification_count->whereOr("c",0);
                    $room_qualification_count->whereOr("d",0);
                })->fetchSql(true)  ->find();
                
        var_dump($room_qualification_count);die;

SELECT
 * 
FROM
 `fa_room` 
WHERE  `level` = '1'  
AND (  `a` = 1  OR `b` = 0  OR `c` = 0  OR `d` = 0 )
 LIMIT 1
