Examples

Creating a TimeRange object

use TimeRange;

// Create a new TimeRange
$timeRange1 = new TimeRange('2013-03-31 00:00:00', '2013-04-01 01:09:00');

// You can also use PHP DateTime objects
$start = new DateTime('2000-01-01');
$end = new DateTime('2000-01-05');
$timeRange2 = new TimeRange($start, $end);

Looping TimeRange

TimeRange supports looping minutes, hours, days and months.

// Echo all days in time range
foreach ($timeRange1->getDays() as $datetime) {
  echo $datetime->format('Y-m-d')."<br>";
}

// Echo every other day in time range backwards
foreach ($timeRange1->getDays(2, TimeRange::BACKWARD) as $datetime) {
  echo $datetime->format('Y-m-d')."<br>";
}

// Echo all minutes
foreach ($timeRange1->getMinutes() as $datetime) {
  echo $datetime->format('Y-m-d H:i')."<br>";
}

Check if two TimeRanges overlap

$timeRange1 = new TimeRange('2013-03-31 00:00', '2013-04-01 01:09');
$timeRange2 = new TimeRange('2013-01-01 12:30', '2013-01-05 14:00');

if ($timeRange1->overlaps($timeRange2)) {
  echo "Ranges overlap";
}

// Check if date overlaps the TimeRange
if ($timeRange1->overlaps("2013-04-01", TimeRange::DAY)) {
  ...
}

Changing start or end of the range

$timeRange = new TimeRange('2013-03-31 00:00', '2013-04-01 01:09');
$timeRange->setStart('2013-02-28');
$timeRange->setEnd('2013-03-03');
