The calculation in the last step does not take into account the hours, minutes and seconds in the date difference (as they're not included in the %a format).Using that, we can convert the number of days into seconds by multiplying it with hours in a day, minutes in an hour, and seconds in a minute (i.e. Using the %r%a format together, we can get the negative/positive number of days.Using the %a formatting character gives us the total number of days between two dates.Using the %r formatting character, adds the minus sign when the result is negative.The calculation works in the following way: $seconds = $daysInSecs + $hoursInSecs + $minsInSecs + $diff->s You can calculate the number of seconds between the two dates in the following way: Please note that comparing timestamps could lead to problems with dates before 1970 and after 2038.Ĭalculating Number of Seconds Between Two Dates For example:Įcho $end->getTimestamp() - $start->getTimestamp() // output: 284169600 We can simply compare timestamps of two dates to get the difference in seconds. Therefore, you can either get the difference of the timestamps of the two dates or calculate the number of seconds yourself:Ĭomparing Timestamps to Get Number of Seconds Between Two Dates By default there's no method available on the DateTime or DateInterval class to get the difference between two DateTime objects in seconds.
