如何使用PHP和MySQL从每天的表中获取值

Question

I need one help.I need to fetch value from table as per day from a week using PHP and MySQL.I am explaining my table below.

db_comment:

id   comment  member_id    comment_status   day

1     Hii         52            1            1

2     Hii         52             1            2
3     Hii         52             1            3

4     Hii         52             1            4

5     Hii         52             1            5

6     Hii         52             1            6

7     Hii         52             1            7

Here my requirement is for same member_id from lower day(i.e-1) to higher day(i.e-7) if all comment_status value is 1 then true will return (lets say $isComment=true) with comment value (i.e-$comm=Hii) and if any of day comment_status value is 0 for same member_id then false value will return (i.e-$isComment=false) with comment value as blank(i.e-$comm=''). I am explaining my query below.

$sql=mysqli_query($connect,"select * from db_comment where member_id=52");

Please help me to fetch value as per explained above.
