I am working on a code which will send users reminders like 10 minutes,2 hours, a day, one week before their event is due.

I will like to get the datetime after the reminder has been removed from the startdate

$startdate = "2010-07-10 01:00:00"; // date chosen by the user $reminder = "10 * 60"; // 10 minutes converted to seconds //I will like to get the time after each of the following has been reducted. $reminder = "60*60" // 1 hour $reminder = "24*60*60" // 1 day $reminder = "24*7*60*60" 1 week

Thanks in advance.

Check this code.

<? function timeAfter($timestamp, $granularity=2, $format='Y-m-d H:i:s'){ $difference = $timestamp - time(); if($difference < 0) return '0 seconds ago'; // if difference is lower than zero check server offset elseif($difference < 864000){ // if difference is over 10 days show normal time form $periods = array('week' => 604800,'day' => 86400,'hr' => 3600,'min' => 60,'sec' => 1); $output = ''; foreach($periods as $key => $value){ if($difference >= $value){ $time = round($difference / $value); $difference %= $value; $output .= ($output ? ' ' : '').$time.' '; $output .= (($time > 1 && $key == 'day') ? $key.'s' : $key); $granularity--; } if($granularity == 0) break; } return ($output ? $output : '0 seconds').' after'; } else return date($format, $timestamp); } $ts = strtotime('2010-07-15 7:00:00'); echo timeAfter($ts,4); exit; ?>

Thanks, but it is not what i was expecting. I
I am getting close but i still have a problem
let's say

$reminder ="300"; // 5 minutes * 60 seconds (to convert to seconds) $timefromreminder = date('h:i:s', strtotime("-$reminder seconds")); // this will give 5 minutes minus the current time //but what i am looking for is to be able to do this $event_start_time = '11:45:00'; $timefromreminder2 = date('$event_start_time', strtotime("-$reminder seconds")); //Now it does not give 11:40:00 instead it does nothing and gives the same 11:45:00

I want to be able to delete 5 minutes from a time i specify

Get the current time as a timestamp [ $wk = strtotime("$my_date $my_time"); ]

Subtract your 5 minutes / 300 seconds from it [ $wk2 = $wk - 300; ].

Then you can do whatever you need to do with it:
e.g. display it: [ echo date("Y-m-d H:i:s",$wk2); ]
