我不知道“淡季”或“死”是否是我问题中的正确定义。无论如何,这是解释:
我的数组中有$period['from']
和$period['to']
,我需要计算2013年的“死亡或淡季”时段。
输入期间示例:
From To
2013-04-01 2013-06-01
2013-07-15 2013-07-20
2013-09-01 2013-10-31
和死区将是(输出):
From To
2013-01-01 2013-03-31
2013-06-02 2013-07-14
2013-07-21 2013-08-31
2013-11-10 2013-12-31
我完全坚持这个。 任何帮助将不胜感激,

试试这个:
function dateDiff(array $dates, $startAt = null, $endAt = null) {
if ($startAt === null) {
$startAt = date("Y-01-01");
$start = strtotime($startAt) - 86400;
} else {
$start = strtotime($startAt);
}
if ($endAt === null) {
$endAt = date("Y-12-31");
}
$result = array();
foreach ($dates as $row) {
$to = strtotime($row['from']);
$result[] = array('from' => date('Y-m-d', $start + 86400), 'to' => date('Y-m-d', $to - 86400));
$start = strtotime($row['to']);;
}
$result[] = array('from' => date('Y-m-d', $start + 86400), 'to' => date('Y-m-d', strtotime($endAt)));
return $result;
}
$dates = array(
array('from' => '2013-04-01', 'to' => '2013-06-01'),
array('from' => '2013-07-15', 'to' => '2013-07-20'),
array('from' => '2013-09-01', 'to' => '2013-10-31'),
);
print_r(dateDiff($dates));
这将产生:
Array (
[0] => Array ( [from] => 2013-01-01 [to] => 2013-03-31 )
[1] => Array ( [from] => 2013-06-02 [to] => 2013-07-14 )
[2] => Array ( [from] => 2013-07-21 [to] => 2013-08-31 )
[3] => Array ( [from] => 2013-11-01 [to] => 2013-12-31 )
)
