比如
$aa="2013-12-25";
$bb=time();
我想列出2013-12距離現在的月份
array(12) {
[1] => string(6) "2013-12"
[2] => string(6) "2014-1"
[3] => string(6) "2014-2"
[4] => string(6) "2014-3"
[5] => string(6) "2014-...."
}
現在只能列出當年的當前月份
for ($i = 1; $i <= date('m'); $i++) {
$dates[$i] = date('Y-'.$i, strtotime(date("Y-m-d")));
}

先說感想吧
- 這種“要知道迴圈多少次略有困難”的問題用
while會讓邏輯清晰不少
- strtotime大殺器
- PHP4.3+
- //My Code又短又清楚,哼
php//http://3v4l.org/vuef4function monthToToday($past, $now, $format = 'Y-m') { $current = strtotime(date('Y-m-1', strtotime($past))); $result = array(); while($current < $now) { $result[] = date($format, $current); $current = strtotime('+1 month', $current); } //包含當前月份 $result[] = date($format, $current); return $result;}print_r(monthToToday('2013-12-25', time()));die;
兩者時間戳記相減
$monthDiffed) { $m = $month; $month = $monthDiffed; $monthDiffed = $m; } $monthDiffed = $monthDiffed->modify("last day of -1 month"); $month = $month->modify("first day of +1 month"); $result = array(); while($month <= $monthDiffed) { $result[] = $month->format( $format ); $month = $month->modify("+1 month"); } return $result;}print_r( diffMonth("2014-6") );print_r( diffMonth("2014-6", "Y/m", "2013-6") );
$aa="2003-02-25";$bb = date("Y-m-d",time());function datediffage($before, $after) { $b = getdate($before); $a = getdate($after);$y=$m=0;if ($a['mon']==1) { //1月,借年 $y=$a['year']-$b['year']-1;$m=$a['mon']-$b['mon']+12;}else { if ($a['mon']>=$b['mon']+1) { //借月後,月相減為正 $y=$a['year']-$b['year'];$m=$a['mon']-$b['mon']-1; } else { //借月後,月相減為負,借年 $y=$a['year']-$b['year']-1;$m=$a['mon']-$b['mon']+12-1; }}$datearr = array();$totalm = "";if( $y > 0 ){ $totalm = $y*12;//大於1年,轉換成月份數}$totalm += $m;for ($i=0; $i < $totalm; $i++) { array_push($datearr, date("Y-m",mktime(0,0,0,$b['mon']+$i,$d,$b['year'])));}return $datearr;
}
print_r(datediffage(strtotime($aa),strtotime($bb)));

感謝原作者,有修改。
echo (new DateTime('2013-12'))->diff(new DateTime(date('Y-m')))->format('%y year %m month %d days');
結果是從目標時間到今天已經過去幾年幾月幾天
年x12+month = 已經過去幾個月
$date = new DateTime('2013-12');$now = date('Ym');$months = array();while ($date->format('Ym')<=$now) { array_push($months, $date->format('Y-m')); $date->modify('+1 month');}print_r($months);
擷取目標時間到現在的月份詳情
$aa = '2013-12-25';
$a = strtotime($aa);
$b = array();
while($a $b[] = date('Y-m',$a);
$a = strtotime('+1 month',$a);
}
var_dump($b);
寫完發現和mcfog思路差不多
這個問題貌似都有問題啊,
時間差出來了,那麼,你一個月是按28天算,還是30天或31天算呢?
年是按365天還是366天算呢?
