mahenda Posted August 9, 2020 Share Posted August 9, 2020 how to calculate the difference between the current datetime from the stored one(ie date_field = 2020-08-09 23:13:06) in order to compare with 15min, i mean if the resulted time exceed 15 min and not the same day(date) the provided link will show expire message. i.e $some_variable = $date_in_db - current_date; if((time() - $some_variable > 15*60) && not the same day or the same day){ echo 'the link has expired'; } Quote Link to comment Share on other sites More sharing options...

gw1500se Posted August 10, 2020 Share Posted August 10, 2020 It doesn't matter. Strtotime includes the date. Quote Link to comment Share on other sites More sharing options...
