我有两个表格日期：
Start Date: 2007-03-24
End Date: 2009-06-26
现在我需要通过以下形式找到这两者之间的区别：
2 years, 3 months and 2 days
如何在PHP中执行此操作？
当前回答
前段时间，我编写了一个format_date函数，因为它提供了许多关于日期的选项：
function format_date($date, $type, $seperator="-")
{
if($date)
{
$day = date("j", strtotime($date));
$month = date("n", strtotime($date));
$year = date("Y", strtotime($date));
$hour = date("H", strtotime($date));
$min = date("i", strtotime($date));
$sec = date("s", strtotime($date));
switch($type)
{
case 0: $date = date("Y".$seperator."m".$seperator."d",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 1: $date = date("D, F j, Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 2: $date = date("d".$seperator."m".$seperator."Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 3: $date = date("d".$seperator."M".$seperator."Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 4: $date = date("d".$seperator."M".$seperator."Y h:i A",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 5: $date = date("m".$seperator."d".$seperator."Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 6: $date = date("M",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 7: $date = date("Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 8: $date = date("j",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 9: $date = date("n",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 10:
$diff = abs(strtotime($date) - strtotime(date("Y-m-d h:i:s")));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
$date = $years . " years, " . $months . " months, " . $days . "days";
}
}
return($date);
}
其他回答
这是我的职责。所需PHP>=5.3.4。它使用DateTime类。非常快，很快，可以区分两个日期，甚至所谓的“开始时间”。
if(function_exists('grk_Datetime_Since') === FALSE){
function grk_Datetime_Since($From, $To='', $Prefix='', $Suffix=' ago', $Words=array()){
# Est-ce qu'on calcul jusqu'à un moment précis ? Probablement pas, on utilise maintenant
if(empty($To) === TRUE){
$To = time();
}
# On va s'assurer que $From est numérique
if(is_int($From) === FALSE){
$From = strtotime($From);
};
# On va s'assurer que $To est numérique
if(is_int($To) === FALSE){
$To = strtotime($To);
}
# On a une erreur ?
if($From === FALSE OR $From === -1 OR $To === FALSE OR $To === -1){
return FALSE;
}
# On va créer deux objets de date
$From = new DateTime(@date('Y-m-d H:i:s', $From), new DateTimeZone('GMT'));
$To = new DateTime(@date('Y-m-d H:i:s', $To), new DateTimeZone('GMT'));
# On va calculer la différence entre $From et $To
if(($Diff = $From->diff($To)) === FALSE){
return FALSE;
}
# On va merger le tableau des noms (par défaut, anglais)
$Words = array_merge(array(
'year' => 'year',
'years' => 'years',
'month' => 'month',
'months' => 'months',
'week' => 'week',
'weeks' => 'weeks',
'day' => 'day',
'days' => 'days',
'hour' => 'hour',
'hours' => 'hours',
'minute' => 'minute',
'minutes' => 'minutes',
'second' => 'second',
'seconds' => 'seconds'
), $Words);
# On va créer la chaîne maintenant
if($Diff->y > 1){
$Text = $Diff->y.' '.$Words['years'];
} elseif($Diff->y == 1){
$Text = '1 '.$Words['year'];
} elseif($Diff->m > 1){
$Text = $Diff->m.' '.$Words['months'];
} elseif($Diff->m == 1){
$Text = '1 '.$Words['month'];
} elseif($Diff->d > 7){
$Text = ceil($Diff->d/7).' '.$Words['weeks'];
} elseif($Diff->d == 7){
$Text = '1 '.$Words['week'];
} elseif($Diff->d > 1){
$Text = $Diff->d.' '.$Words['days'];
} elseif($Diff->d == 1){
$Text = '1 '.$Words['day'];
} elseif($Diff->h > 1){
$Text = $Diff->h.' '.$Words['hours'];
} elseif($Diff->h == 1){
$Text = '1 '.$Words['hour'];
} elseif($Diff->i > 1){
$Text = $Diff->i.' '.$Words['minutes'];
} elseif($Diff->i == 1){
$Text = '1 '.$Words['minute'];
} elseif($Diff->s > 1){
$Text = $Diff->s.' '.$Words['seconds'];
} else {
$Text = '1 '.$Words['second'];
}
return $Prefix.$Text.$Suffix;
}
}
我更喜欢使用date_create和date_diff对象。
代码：
$date1 = date_create("2007-03-24");
$date2 = date_create("2009-06-26");
$dateDifference = date_diff($date1, $date2)->format('%y years, %m months and %d days');
echo $dateDifference;
输出：
2 years, 3 months and 2 days
有关更多信息，请阅读PHP date_diff手册
根据手册date_diff是的别名日期时间：：diff（）
我投票支持jurka的答案，因为这是我最喜欢的，但我有一个pre-php.5.3版本。。。
我发现自己在解决一个类似的问题——这就是我最初如何回答这个问题——但只是需要时间上的差异。但我的函数也很好地解决了这个问题，而且我自己的库中没有任何地方可以将它保存在不会丢失和遗忘的地方，所以……希望这对某人有用。
/**
*
* @param DateTime $oDate1
* @param DateTime $oDate2
* @return array
*/
function date_diff_array(DateTime $oDate1, DateTime $oDate2) {
$aIntervals = array(
'year' => 0,
'month' => 0,
'week' => 0,
'day' => 0,
'hour' => 0,
'minute' => 0,
'second' => 0,
);
foreach($aIntervals as $sInterval => &$iInterval) {
while($oDate1 <= $oDate2){
$oDate1->modify('+1 ' . $sInterval);
if ($oDate1 > $oDate2) {
$oDate1->modify('-1 ' . $sInterval);
break;
} else {
$iInterval++;
}
}
}
return $aIntervals;
}
测试：
$oDate = new DateTime();
$oDate->modify('+111402189 seconds');
var_dump($oDate);
var_dump(date_diff_array(new DateTime(), $oDate));
结果是：
object(DateTime)[2]
public 'date' => string '2014-04-29 18:52:51' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'America/New_York' (length=16)
array
'year' => int 3
'month' => int 6
'week' => int 1
'day' => int 4
'hour' => int 9
'minute' => int 3
'second' => int 8
我从这里得到了最初的想法，我对其进行了修改以供使用（我希望我的修改也会显示在该页面上）。
通过从$aIntervals数组中删除不需要的间隔（例如“周”），或者添加$aExclude参数，或者在输出字符串时过滤掉它们，可以非常容易地删除它们。
// If you just want to see the year difference then use this function.
// Using the logic I've created you may also create month and day difference
// which I did not provide here so you may have the efforts to use your brain.
// :)
$date1='2009-01-01';
$date2='2010-01-01';
echo getYearDifference ($date1,$date2);
function getYearDifference($date1=strtotime($date1),$date2=strtotime($date2)){
$year = 0;
while($date2 > $date1 = strtotime('+1 year', $date1)){
++$year;
}
return $year;
}
我有一些简单的逻辑：
<?php
per_days_diff('2011-12-12','2011-12-29')
function per_days_diff($start_date, $end_date) {
$per_days = 0;
$noOfWeek = 0;
$noOfWeekEnd = 0;
$highSeason=array("7", "8");
$current_date = strtotime($start_date);
$current_date += (24 * 3600);
$end_date = strtotime($end_date);
$seassion = (in_array(date('m', $current_date), $highSeason))?"2":"1";
$noOfdays = array('');
while ($current_date <= $end_date) {
if ($current_date <= $end_date) {
$date = date('N', $current_date);
array_push($noOfdays,$date);
$current_date = strtotime('+1 day', $current_date);
}
}
$finalDays = array_shift($noOfdays);
//print_r($noOfdays);
$weekFirst = array("week"=>array(),"weekEnd"=>array());
for($i = 0; $i < count($noOfdays); $i++)
{
if ($noOfdays[$i] == 1)
{
//echo "This is week";
//echo "<br/>";
if($noOfdays[$i+6]==7)
{
$noOfWeek++;
$i=$i+6;
}
else
{
$per_days++;
}
//array_push($weekFirst["week"],$day);
}
else if($noOfdays[$i]==5)
{
//echo "This is weekend";
//echo "<br/>";
if($noOfdays[$i+2] ==7)
{
$noOfWeekEnd++;
$i = $i+2;
}
else
{
$per_days++;
}
//echo "After weekend value:- ".$i;
//echo "<br/>";
}
else
{
$per_days++;
}
}
/*echo $noOfWeek;
echo "<br/>";
echo $noOfWeekEnd;
echo "<br/>";
print_r($per_days);
echo "<br/>";
print_r($weekFirst);
*/
$duration = array("weeks"=>$noOfWeek, "weekends"=>$noOfWeekEnd, "perDay"=>$per_days, "seassion"=>$seassion);
return $duration;
?>
