date/time calculation in php

Recommended Posts

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';

}

You need to use strtotime. It will create a time stamp then you compare the time stamps directly.

if(strtotime("+15 minutes") < strtotime($some_variable)) {

It doesn't matter. Strtotime includes the date.
