8      5      2020-03-30        2020-03-31 02:00:00       2
9      5      2020-03-30        2020-03-31 03:00:00       2
10     5      2020-03-30        2020-03-31 04:00:00       2
11     5      2020-03-30        2020-03-31 05:00:00       2

13     5      2020-03-30        2020-03-31 07:00:00       2
14     5      2020-03-30        2020-03-31 08:00:00       2
15     5      2020-03-30        2020-03-31 09:00:00       2
16     5      2020-03-30        2020-03-31 10:00:00       2
17     5      2020-03-30        2020-03-31 11:00:00       2

My goal is to get all data that is between 7PM - 12NOON.

In my php code i am passing a parameter which is the current_date(Assume that today is March 30) for this day. So that i can put it on my where clause in my database query.

$shift_date = '';

$shift_date = ($shift_date != '') ?
            DateTime::createFromFormat('m-d-Y', $shift_date, new DateTimeZone('Asia/Manila')) :
            DateTime::createFromFormat('Y-m-d', date("Y-m-d"), new DateTimeZone('Asia/Manila'));

$current_hour = DateTime::createFromFormat('Y-m-d H:i:s', $shift_date->format('Y-m-d') .' 19:00:00', new DateTimeZone('Asia/Manila')); 

//2020-03-30 19:00:00

And this is my query, with this query i have no problem on getting the data because it is still March 30.

SELECT value,time,current_date,group
FROM table
WHERE time >='2020-03-30 19:00:00' AND time <= DATE_ADD("2020-03-30 19:00:00", INTERVAL 16 HOUR)
AND group = 2;

The dilema that i am having is what if the date gets to 2020-03-31 :00:00:00 then this line of code in my php will have a value of 2020-03-31: 19:00:00 then i will not already get the data that i want.

$shift_date = '';

$shift_date = ($shift_date != '') ?
            DateTime::createFromFormat('m-d-Y', $shift_date, new DateTimeZone('Asia/Manila')) :
            DateTime::createFromFormat('Y-m-d', date("Y-m-d"), new DateTimeZone('Asia/Manila'));

$current_hour = DateTime::createFromFormat('Y-m-d H:i:s', $shift_date->format('Y-m-d') .' 19:00:00', new DateTimeZone('Asia/Manila')); 

//2020-03-31 19:00:00

I should still get the data that i need between the March 30 7PM - March 31 11 noon. I am really stuck with this problem that i have. Thank you for all the advance help that will give me time to help me on this.

Hi i know my question is really confusing, but i already solve it.

the end time is always 11PM so i just need to -12 hours so i can fetch all data base on the current_date in my database;

$shift_date = date_create(date("Y-m-d"));
$shift_date->modify("-12 hours");
