Adding time in PHP

Question

I am pulling a datetime from a mysql db and i would like to add X hours to it then compare it to the current time. So far i got

$dateNow = strtotime(date(\'Y         


        

Answer 1

Assuming that the timestamp returned by the DB is in SQL format, the following should work fine:

$dbTime = strtotime($row[0]);
$nowTime = time();

$future_dbTime = strtotime("+4 hours", $dbTime);

$diff_time_seconds = $nowTime - $dbTime;

if ($diff_time_seconds > 0) {
       echo "The current time is greater than the database time by:\n";
       $not_equal = true;

    }
if ($diff_time_seconds == 0) {
       echo "The current time is equal to the database time!";
    }
if ($diff_time_seconds < 0) {
       echo "The current time is less than the database time by:\n";
       $not_equal = true;
    }

if ($not_equal) {
$diff_time_abs_seconds = abs($diff_time_seconds);
echo date('h:m:s', $diff_time_abs_seconds);
}

Answer 2

time() and strtotime() result in unix timestamps in seconds, so you can do something like the following, provided your db and do your comparison:

$fourHours = 60 * 60 * 4;
$futureTime = time() + $fourHours;
