PHP round time() up (future) to next multiple of 5 minutes

Question

How do I round the result of time() up (towards the future) to the next multiple of 5 minutes?

Answer 1

Try this function:

function blockMinutesRound($hour, $minutes = '5', $format = "H:i") {
   $seconds = strtotime($hour);
   $rounded = round($seconds / ($minutes * 60)) * ($minutes * 60);
   return date($format, $rounded);
}

//call 
 blockMinutesRound('20:11');// return 20:10
