>我想知道如果满足某些特定条件，是否可以将给定的日期范围拆分为 2 个单独的日期范围？
我正在建立一个假期预订系统，如果假期预订超过 2 年，则需要拆分日期。例：
start date: 22-12-2013
end date: 04-01-2014
使用上面的日期，我想将它们分成 2 个日期范围，所以我最终会得到这样的东西：
start date: 22-12-2013
end date: 31-12-2013
然后：
start date: 01-01-2014
end date: 04-01-2014
这可能吗？如果是这样，有人可以指出我需要在谷歌中搜索的正确方向吗？
如果你想拆分更多的月份，你可以使用这个函数：
function getMonthRanges($start, $end) {
$timeStart = strtotime($start);
$timeEnd = strtotime($end);
$out = [];
$milestones[] = $timeStart;
$timeEndMonth = strtotime('first day of next month midnight', $timeStart);
while ($timeEndMonth < $timeEnd) {
$milestones[] = $timeEndMonth;
$timeEndMonth = strtotime('+1 month', $timeEndMonth);
}
$milestones[] = $timeEnd;
$count = count($milestones);
for ($i = 1; $i < $count; $i++) {
$out[] = [
'start' => $milestones[$i - 1], // Here you can apply your formatting (like "date('Y-m-d H:i:s', $milestones[$i-1])") if you don't won't want just timestamp
'end' => $milestones[$i] - 1
];
}
return $out;
}
用：
$result = getMonthRanges('15-11-2014', '19-11-2014');
结果：
Array
(
[0] => Array
(
[start] => 1418594400
[end] => 1420063199
)
[1] => Array
(
[start] => 1420063200
[end] => 1422741599
)
[2] => Array
(
[start] => 1422741600
[end] => 1425160799
)
[3] => Array
(
[start] => 1425160800
[end] => 1426715999
)
)
人类可读的结果：
array_walk_recursive($result, 'applyFormat');
function applyFormat(&$item)
{
$item = date('Y-m-d H:i:s', $item);
}

这是一种非常基本的方法，但我认为调查这样的事情可能会很有趣：
$date1 = '22-12-2013';
$date2 = "04-01-2014";
function split_date($d1, $d2)
{
$start_year = substr($d1, -4);
$end_year = substr($d2, -4);
if($end_year > $start_year)
{
$d1 .= ' ['.date('d-m-Y',strtotime("last day of December".$start_year)).'] <br />';
$d2 = '['.date('d-m-Y',strtotime("first day of January".$start_year)).'] ' . $d2;
}
return $d1 . $d2;
}
echo split_date($date1, $date2);

感谢 ilpaijin，这就是我想出的：
$date1 = '22-12-2013';
$date2 = "04-01-2014";
function split_date($d1, $d2)
{
$start_year = substr($d1, -4);
$end_year = substr($d2, -4);
if($end_year > $start_year)
{
$d1 .= ' ['.date('d-m-Y',strtotime("31-12-".$start_year)).'] <br />';
$d2 = '['.date('d-m-Y',strtotime("01-01-".$start_year."+1 years")).'] ' . $d2;
}
return $d1 . $d2;
}
echo split_date($date1, $date2);
如果有人想将日期范围拆分为任意年份，以下是实现。
$date1 = '22-12-2013';
$date2 = '04-01-2017';
$dA = array();
function split_date($d1, $d2, &$dA)
{
$start_year = substr($d1, -4);
$end_year = substr($d2, -4);
if($end_year > $start_year)
{
$dA[] = $d1;
$dA[] = date('d-m-Y',strtotime("31-12-".$start_year));
if($end_year - $start_year == 1)
{
$dA[] = date('d-m-Y',strtotime("01-01-".$start_year."+1 years"));
$dA[] = $d2;
}else
{
split_date(date('d-m-Y',strtotime("01-01-".$start_year."+1 years")), $d2, $dA);
}
}else if($end_year == $start_year)
{
$dA[] = $d1;
$dA[] = $d2;
}
}
split_date($date1, $date2, $dA);
print_r($dA);
//Answer
Array
(
[0] => 22-12-2013
[1] => 31-12-2013
[2] => 01-01-2014
[3] => 31-12-2014
[4] => 01-01-2015
[5] => 31-12-2015
[6] => 01-01-2016
[7] => 31-12-2016
[8] => 01-01-2017
[9] => 04-01-2017
)
非常简单的方法。您可以拆分日期范围 支持所有类型的日期格式。
function split_date($start_date,$end_date){
while($start_date < $end_date){
$end = date("Y-m-d", strtotime("Last day of December", strtotime($start_date)));
if($end_date<$end){
$end = $end_date;
}
$dates[] =array('start'=>$start_date,'end'=>$end);
$start_date =date("Y-m-d", strtotime("+1 day", strtotime($end)));
}
return $dates;
}
$dates = split_date('2011-01-02','2013-01-04');
print_r($dates);
