Question

开始日期= 2015-01-01 结束日期= 2015-02-01

date = 2015-01-15

我想要两个像这样的间隔

间隔1 开始日期= 2015-01-01 结束日期= 2015-01-15

间隔2 开始日期= 2015-01-16 结束日期= 2015-02-01

我的代码看起来像这样

<?php 

$fromdate = '2015-12-01';
$todate   ='2015-01-01';

if ($fromdate < '2015-12-18' && $todate > '2015-12-18')
{
 // here i have to split interval into two intervals and get data from both tables old_orders and new_orders
    $fromdate1 = '2015-12-01'; $todate1 = '2015-12-15';
    $fromdate2 = '2015-12-16'; $todate2 = '2015-01-01';



$query1 = "SELECT * FROM new_orders WHERE date BETWEEN '".$fromdate1."' AND '".$todate1."'";
$query2 = "SELECT * FROM new_orders WHERE date BETWEEN '".$fromdate2."' AND '".$todate2."'";

}
else if ($fromdate > '2015-12-18')
{
    $query1 = "SELECT * FROM new_orders WHERE date BETWEEN '".$fromdate."' AND '".$todate."'";
}
else if ($todate < '2015-12-18')
{
    $query1 = "SELECT * FROM old_orders WHERE date BETWEEN '".$fromdate."'" AND '".$todate."'";
}

Answer 1

试试这个：

<?php

$startDate = '2015-01-01';
$endDate = '2015-02-01';
$date = '2015-01-15';

$intervals = array();

$intervals[] = array('startDate'=>$startDate, 'endDate'=>$date);
$intervals[] = array('startDate'=>date('Y-m-d', strtotime($date . ' +1 day')), 'endDate'=>$endDate);

在$intervals数组中，您的结构如下：

Array
(
    [0] => Array
        (
            [startDate] => 2015-01-01
            [endDate] => 2015-01-15
        )

    [1] => Array
        (
            [startDate] => 2015-01-16
            [endDate] => 2015-02-01
        )
)

Answer 2

如果我理解你，你就需要这样的东西：

function isDateBetweenDates ($date, $startDate, $endDate) {
     $strDate = strtotime($date);
     $strStartDate = strtotime($startDate);
     $strEndDate = strtotime($endDate);

     return ($strDate >= $strStartDate && $strDate <= $strEndDate);
}

$date = "2015-01-15";
$startDate = "2015-01-01";
$endDate = "2015-02-01";

class Interval {}
$interval = new Interval();

if (isDateBetweenDates($date, $startDate, $endDate)) {
        $interval->firstPart = array(
            "start" => $startDate,
            "end" => $date
        );

        $newDate = new DateTime($date);
        $newDate->modify("1 day");

        $interval->secondPart = array(
            "start" => $newDate->format("Y-m-d"),
            "end" => $endDate
        );
}

最好的问候。
