我想知道是否有一些简单的方法来确定季节:春季,夏季,秋季或冬季。我必须制作一份“简历”,如果一段时间的工作大致适合一个季节(例如,不完全相同,但错误时间为+/- 10天),我就会回复春季,夏季,秋季或冬季。
像:
(西班牙夏季是7月21日至9月20日)
知道怎么做吗?

看起来这个人已经写了这个函数:http://biostall.com/get-the-current-season-using-php
即使有半球支持!
但这应该可以解决问题:
<?php
function getSeason($date) {
$season_names = array('Winter', 'Spring', 'Summer', 'Fall');
if (strtotime($date) < strtotime($date_year.'-03-21') || strtotime($date) >= strtotime($date_year.'-12-21')) {
return $season_names[0]; // Must be in Winter
} elseif (strtotime($date) >= strtotime($date_year.'-09-23')) {
return $season_names[3]; // Must be in Fall
} elseif (strtotime($date) >= strtotime($date_year.'-06-21')) {
return $season_names[2]; // Must be in Summer
} elseif (strtotime($date) >= strtotime($date_year.'-03-21')) {
return $season_names[1]; // Must be in Spring
}
}

当你正在寻找一个时期的一个季节我很快写了这个功能,它可以改进,可能有一些错误,但你有一些地方可以开始。
function season($period)
{
$seasons = array(
'spring' => array('March 21' , 'June 20'),
'summer' => array('June 21' , 'September 22'),
'fall' => array('September 23' , 'December 20'),
'winter' => array('December 21' , 'March 20')
);
$seasonsYear = array();
$start = strtotime($period[0]);
$end = strtotime($period[1]);
$seasonsYear[date('Y', $start)] = array();
if (key(current($seasonsYear)) != date('Y', $end))
$seasonsYear[date('Y', $end)] = array();
foreach ($seasonsYear as $year => &$seasonYear)
foreach ($seasons as $season => $period)
$seasonYear[$season] = array(strtotime($period[0].' '.$year), strtotime($period[1].' '.($season != 'winter' ? $year : ($year+1))));
foreach ($seasonsYear as $year => &$seasons) {
foreach ($seasons as $season => &$period) {
if ($start >= $period[0] && $end <= $period[1])
return ucFirst($season).' '.$year;
if ($start >= $period[0] && $start <= $period[1]) {
if (date('Y', $end) != $year)
$seasons = $seasonsYear[date('Y', $end)];
$year = date('Y', $end);
$nextSeason = key($seasons);
$nextPeriod = current($seasons);
do {
$findNext = ($end >= $nextPeriod[0] && $end <= $nextPeriod[1]);
$nextSeason = key($seasons);
$nextPeriod = current($seasons);
} while ($findNext = False);
$diffCurr = $period[1]-$start;
$diffNext = $end-$nextPeriod[0];
if ($diffCurr > $diffNext)
return ucFirst($season).' '.$year;
else {
return ucFirst($nextSeason).' '.$year;
}
}
}
}
}
echo season(array('07/20/2010', '08/20/2010'));
echo "\n";
echo season(array('06/25/2010', '09/30/2010'));
echo "\n";
echo season(array('08/25/2010', '11/30/2010'));
echo "\n";
echo season(array('12/21/2010', '01/01/2011'));
echo "\n";
echo season(array('12/21/2010', '03/25/2011'));
结果:
/*
Summer 2010
Summer 2010
Fall 2010
Winter 2010
Winter 2011
*/
除了你想要的“季节溢出”之外:
if (date('Y', $end) != $year)
return $year.'-'.date('Y', $end);
而不是:
if (date('Y', $end) != $year)
$seasons = $seasonsYear[date('Y', $end)];
$year = date('Y', $end);
注意:冬天来了。

以下是您需要做的概述:
确定你的季节性界限。如果您打算在国际范围内这样做,这是一项很重要的大型工作!
当提供日期范围时,首先确定每个季节中该范围的确切天数。
您希望输出如下:
Range | Days | complete?
Su10 | 12 | 0
A10 | 90 | 1
W10 | 02 | 0
1
。如果是,请选择那个季节。如果有更多内容,或者没有,请返回false
。
