How about something like this: $hstart = 7; $hend = 19; $interval = 15; for($h=$hstart; $h < $hend; $h++) { for($m=0; $m < 60; $m += $interval) { echo sprintf("%d:%02d",$h,$m); } } Used sprintf in order to make 0 minutes display as 00. This would be a great candidate for something to make into a function... -- Kelly Hallman // Ultrafancy
