function getStartAndEndUnixTimestamp($year = 0, $month = 0, $day = 0)
{
	if(empty($year))
	{
		$year = date("Y");
	}

	$start_year = $year;
	$start_year_formated = str_pad(intval($start_year), 4, "0", STR_PAD_RIGHT);
	$end_year = $start_year + 1;
	$end_year_formated = str_pad(intval($end_year), 4, "0", STR_PAD_RIGHT);

	if(empty($month))
	{
		//只设置了年份
		$start_month_formated = '01';
		$end_month_formated = '01';
		$start_day_formated = '01';
		$end_day_formated = '01';
	}
	else
	{

		$month > 12 || $month < 1 ? $month = 1 : $month = $month;
		$start_month = $month;
		$start_month_formated = sprintf("%02d", intval($start_month));

		if(empty($day))
		{
			//只设置了年份和月份
			$end_month = $start_month + 1;
			
			if($end_month > 12)
			{
				$end_month = 1;
			}
			else
			{
				$end_year_formated = $start_year_formated;
			}
			$end_month_formated = sprintf("%02d", intval($end_month));
			$start_day_formated = '01';
			$end_day_formated = '01';
		}
		else
		{
			//设置了年份月份和日期
			$startTimestamp = strtotime($start_year_formated.'-'.$start_month_formated.'-'.sprintf("%02d", intval($day))." 00:00:00");
			$endTimestamp = $startTimestamp + 24 * 3600 - 1;
			return array('start' => $startTimestamp, 'end' => $endTimestamp);
		}
	}

	$startTimestamp = strtotime($start_year_formated.'-'.$start_month_formated.'-'.$start_day_formated." 00:00:00");			
	$endTimestamp = strtotime($end_year_formated.'-'.$end_month_formated.'-'.$end_day_formated." 00:00:00") - 1;
	return array('start' => $startTimestamp, 'end' => $endTimestamp);
}

使用例子如下所示:

<?php
echo "<pre>";
$result = getStartAndEndUnixTimestamp(2016);
$result1 = getStartAndEndUnixTimestamp(2016, 8);
$result2 = getStartAndEndUnixTimestamp(2016, 9, 30);
print_r($result);
print_r($result1);
print_r($result2);
?>

结果如下所示:

Array
(
    [start] => 1451577600
    [end] => 1483199999
)
Array
(
    [start] => 1469980800
    [end] => 1472659199
)
Array
(
    [start] => 1475164800
    [end] => 1475251199
)
