Php DatePeriod与DateInterval P1Y去年未生成

php datetime

Php DatePeriod与DateInterval P1Y去年未生成,php,datetime,dateinterval,Php,Datetime,Dateinterval,我有这样一个密码： private function validatePeriodArrayYear() { $this->time->setTimestamp( self::$data['to'] ); $year1 = $this->time->format('Y'); $this->time->setTimestamp( self::$data['from'] ); $year2 = $this->time->

我有这样一个密码：

private function validatePeriodArrayYear()
{
    $this->time->setTimestamp( self::$data['to'] );
    $year1 = $this->time->format('Y');
    $this->time->setTimestamp( self::$data['from'] );
    $year2 = $this->time->format('Y');

    $overlap = $year1 - $year2;

    if( $overlap > 0 ){
        $end = clone $this->time;
        $end->setTimestamp( self::$data['to'] );
        $overlap++;

        $interval = new DateInterval('P1Y');
        $period = new DatePeriod( $this->time, $interval, $end );
        var_dump($period);
        $iteration = -1;

        foreach( $period as $onePeriod ){ 
            var_dump($onePeriod);
            $iteration++;
            if( $iteration > 0 ){
                $onePeriod->setDate( $onePeriod->format('Y'), 1, 1 );
            }
            $from = $onePeriod->getTimestamp();
            $onePeriod->setDate( $onePeriod->format('Y'), 12, 31 );
            $onePeriod->setTime( 23, 59, 59 );
            self::$data['zone'][$iteration] = array( 'from' => $from, 'to' => $onePeriod->getTimestamp()  );
        }

        self::$data['zone'][$iteration]['to'] = self::$data['to'];

    } else {
        self::$data['zone'][] = array( 'from' => self::$data['from'], 'to' => self::$data['to'] );
    }

变量 var_dump（）输出函数如下所示：

转换为日期：
2012年12月1日至2012年12月31日
2013年1月1日至2014年1月13日
现在，如果它不会生成此错误，请更正我，本例中的错误在哪里：
2012年12月1日至2012年12月31日
2013年1月1日-2013年12月31日
2014年1月1日至2014年1月13日

补充资料谢谢你的回答

编辑 @格拉维奇：谢谢你提供的信息，现在我完全明白了

我突然想到，如果开始和结束的年份是一样的，而我在那一年中只改变了几个月或几天，有时会带来正确的结果，有时会缺少去年的结果

因此，让我进一步分析一下这个问题。

为了澄清，我将使用不同的输入变量，以便更好地理解

变量请注意，

self:：$data['to']

只是缺少了一秒钟，差异超过了3年

代码输出在这种情况下，将在

DatePeriod

class:
内创建三个日期 2012-12-01 00:00:00
2013-12-01 00:00:00
2014-12-01 00:00:00
但最后一个日期被删除，因此类只返回两个

DateTime

对象

现在，我们向变量

self:：$data['to']

添加第二个变量，然后再次运行代码

变量输出在这种情况下，在

DatePeriod

class:
内创建四个日期 2012-12-01 00:00:00
2013-12-01 00:00:00
2014-12-01 00:00:00
2014-12-01 00:00:01
最后日期再次被删除

数学表达 {x|a≤ xa=开始日期
b=结束日期
初始化的x等于a
然后创建每个时段

x=x+句点（在我的例子中，P1Y属于{365366}）

如果我正确理解了您试图做的事情，那么这将帮助您：

$from=newdatetime（“@1354316400”）；
$to=新日期时间（“@138965399”）；
$zones=[]；
对于（$Y=$from->format（'Y'）；$Y format（'Y'）；$Y++）{
$\u from=clone$from；
如果（$Y！=$from->format（'Y'））{
$\u from->setDate（$Y，1，1）；
}
$\u to=克隆$to；
如果（$Y！=$to->格式化（'Y'））{
$\u to->setDate（$Y，12，31）；
}
$zones[]=[
'from'=>$\u from->format（'Y-m-d'），
'至'=>$至->格式（'Y-m-d'），
];
}
打印区（$zones）；

是的，重写方法是解决方案，但我想知道为什么

DatePeriod

没有为年份创建

DateTime

的最后一个对象2014@user3193454：endDate不包括在

DatePeriod

中。您可以通过在将endDate发送到DatePeriod之前增加DateInterval来解决这个问题。
