Get a range of dates as an array using PHP

This handy function lets you specify a start date, an end date, an incremental value (e.g. 1 day) and a date format and returns the full range as an array.

function getDateRange($start, $end, $step, $format) {

    $dateRange 		= [];
    $current 		= strtotime($start);
    $end 			= strtotime($end);

    while ($current <= $end) {

        $dateRange[]	= date($format, $current);
        $current 		= strtotime($step, $current);
    }

    return $dateRange;

}

print_r(getDateRange('2019-01-01', '2019-01-31', '+1 day', 'j M Y'));
print_r(getDateRange('1 January 2019', '31 December 2019', '+1 month', 'Y-m-d'));

It also works with times. E.g. getDateRange('10:30:14', '11:55:14', '+1 minute', 'H:i:s'), getDateRange('10:30:14', '10:32:01', '+1 second', 'H:i:s').
