这是Mysql查询,我不知道如何从MySQL中修剪它所以我想用PHP ..

    SELECT hotelas.name, hotelas.address, hotelas.city, hotelas.country, hotelas.hotel_id 
AS hotelid, 
COUNT( DISTINCT apart.apartman_id ) AS number_of_free_ap, 
COUNT( DISTINCT room.apartman_id ) AS num_of_free_rooms
    FROM hotel AS hotelas
    LEFT JOIN apartman AS apart ON ( apart.apartman_hotel = hotelas.hotel_id
    AND apart.occupied =0
    AND apart.what =1 )
    LEFT JOIN apartman AS room ON ( room.apartman_hotel = hotelas.hotel_id
    AND room.occupied =0
    AND room.what =0 )
    GROUP BY hotelas.hotel_id

表字段是什么,0 - 房间,1 - 公寓

所以我得到了一些列,其中最重要的是计数列,免费房间和免费公寓.所以我有一个测试酒店,完整的0个房间和0个公寓,我想要从这个列表中删除所有其他酒店至少有一个房间或一个公寓可用.

如果您正在查询数据库以获取此信息,并且您可以更改查询,那么这将是最佳选择.

SELECT *
FROM myTable
WHERE
    firstColumn != 0
OR
    secondColumn != 0

如果您从其他来源(CSV或其他)获取PHP,或者您无法控制查询,请使用array_filter():

// i'm assuming each line in your example is an array of values
$myArray = array_filter($myArray, 'noDoubleZeroes');

function noDoubleZeroes($line) {
    return $line[1] != 0 || $line[2] != 0;
}
