$timeArray = array();
$startTime = new \DateTime("2010-01-01 10:00:00");
$endTime = new \DateTime("2010-01-01 12:00:00");
while($startTime < $endTime) {
$timeArray[] = $startTime->format('H:i:s');
$startTime->add(new \DateInterval('PT 15 M'));
}
echo implode(",",$timeArray);

You can also try this -
$dayFrom = strtotime('10:00:00');
$dayTo = strtotime('12:00:00');
while($dayFrom <= $dayTo) {
echo date('H:i:s', $dayFrom);
$dayFrom= strtotime('+ 15 MINUTES', $dayFrom);
}
Output
10:00:00
10:15:00
10:30:00
10:45:00
11:00:00
11:15:00
11:30:00
11:45:00
12:00:00
strtotime()

Another variation on a theme - using DateInterval.
$df='H:i';
$timezone=new DateTimeZone('Europe/London');
$interval=new DateInterval('PT15M');
$ts=date( 'Y-m-d H:i:s', strtotime('10.00am') );
$tf=date( 'Y-m-d H:i:s', strtotime('12.00pm') );
$start=new DateTime( $ts, $timezone );
$end=new DateTime( $tf, $timezone );
while( $start->add( $interval ) <= $end ){
echo $start->format( $df ).'<br />';
}

Answer 4

$dayFrom = "10:00:00";
$dayTo = "12:00:00";
while($endTime<$dayTo){
$endTime = strtotime($dayFrom) + 900;
echo date('h:i:s', $endTime);
}
Try this.
