$result_total = $conn->query($sql_total);
$nb_total=$result_total->num_rows;

}
echo $temp;

Answer 1

I want only the data of last 24 h
This can be done by from_unixtime to convert the int to date
FROM_UNIXTIME(date_post) > NOW() - INTERVAL 1 DAY
counting the occurrence, with max 60 last infos
limit 60
Final query:
select username,
count(*)
from super_table
where FROM_UNIXTIME(date_post) > NOW() - INTERVAL 1 DAY
group by username
order by count(*) desc
limit 60;
No need for
$delay_search=strtotime("+1 day");
$max_user_get=60;
