How to Subtract Minutes

Question

I want to send a reminder email.I don't want to use cron on Linux/Unix/BSD box or Scheduled Tasks on Windows.

I'm trying to subtract 15 minutes from the current time.

here is my code so far (doesn't work):

$days   = date("j",time()); $months = date("n",time()); $years  = date("Y",time()); $hours  = date("G",time()); $mins   = (date("i",time())); $secs   = date("s",time()); $mins   = $mins-15; 

Answer 1

To subtract 15 minutes from the current time, you can use strtotime():

$newTime = strtotime('-15 minutes'); echo date('Y-m-d H:i:s', $newTime);
