php 数组中包含一个月的 DateInterval

DateInterval with one month in php array

如何使用 DateInterval.

获得 php 中的月份间隔

如果我选择 2015 年 8 月 5 日 作为开始日期，17 十月 2015 作为结束日期，那么我的数组输出应该分为3 个数组：

我们可以通过phpDateInterval函数来实现这个东西？

如果您熟悉 PHP 的一些有用的内置 Date/Time 类，这将非常简单。

您可以使用 DateTime, DateInterval and DatePeriod 来实现您的结果。例如：

<?php

// create start/end dates and interval
$start    = new DateTime('05 Aug 2015');
$end      = new DateTime('17 Oct 2015');
$interval = new DateInterval('P1D');

// DatePeriod excludes the last day
// so bump the end date by one
$end->modify('+1 day');

// create a DatePeriod for each day in range
$period = new DatePeriod($start, $interval, $end);

$months = [];

foreach ($period as $date) {
    $months[$date->format('F')][] = $date->format('m/d/Y');
}

print_r($months);

产量：

请注意：您指定要将结果分成三个单独的数组。我假设结果将是动态的——其中月数可能会有所不同——所以我认为你最好生成一个多维结果数组。

在上面的示例中，我使用了月份名称作为键。 $date->format('F') returns一个full textual representation of a month, such as January or March.

如果你想获得 $months 数组中包含的月份列表，你可以这样做：

print_r(array_keys($months));

哪个 returns 键，应该给你足够的信息来访问你需要的数据：

Array
(
    [0] => August
    [1] => September
    [2] => October
)

希望这对您有所帮助:)

您可以试试下面的代码。我不确定，但你可能会得到你想要的东西

$interval = DateInterval::createFromDateString('1 month');
$period   = new DatePeriod($d1, $interval, $d2);

foreach ($period as $dt) {

if($dt->format("Y-m") == date("Y-m", strtotime($date1))){
 $date_array[$dt->format("Y-m")] = array(
  'start_date' => $startDate,
  'end_date' => $dt->format("Y-m-t"),
 );
}else if($dt->format("Y-m") == date("Y-m", strtotime($date2))){
 $date_array[$dt->format("Y-m")] = array(
  'start_date' => $dt->format("Y-m-").'01',
  'end_date' => $endDate,
 );
}else{
 $date_array[$dt->format("Y-m")] = array(
  'start_date' => $dt->format("Y-m-").'01',
  'end_date' => $dt->format("Y-m-t"),
 );
}
}

foreach( $date_array as $d_key=>$da ){
    /* your stuff */
}
