I have a variable called $end_date which gives me the date in epoch format like this: 1539129600. This translates to Wednesday 10 October 2018 00:00:00.
The variable returns different dates, but the time is always the same 00:00:00. Is it possible to take this variable, set the time to 23:59:59 and save it back to a new variable called $end_date_time containing the same date and the new time 23:59:59 in epoch format.
You can do this with the DateTime class, using setTimestamp to convert the timestamp and then setTime to set the time of day, finally getting the new timestamp with format:
$end_date = 1539129600;
$end_of_day = new DateTime(null, new DateTimeZone('UTC'));
$end_of_day->setTimestamp($end_date);
echo $end_of_day->format('Y-m-d H:i:s') . "\n";
$end_of_day->setTime(23,59,59);
echo $end_of_day->format('Y-m-d H:i:s') . "\n";
echo (int)$end_of_day->format('U');
Output:
2018-10-10 00:00:00
2018-10-10 23:59:59
1539215999
