我有一个返回 1 个月前 url 的函数。

我想显示当前选定的月份,但我不能使用简单的当前月份,因为当用户单击指向 1 个月前选定月份的链接时,选定月份会改变并且不会是最新的。

因此,函数返回 2012 年 8 月

如何制作增加 1 个月的小 php 脚本?

到目前为止,我已经:

<?php echo strip_tags(tribe_get_previous_month_text()); ?>

简单的方法:

$next_month = strtotime('august 2012 next month');

更好的方法:

$d = new Date('August 2012');
$next_month = $d->add(new DateInterval('P1M'));

有3个选项/答案

     $givendate is the given date (ex. 2016-01-20)

option 1:
        $date1 = date('Y-m-d', strtotime($givendate. ' + 1 month'));

option 2:
        $date2 = date('Y-m-d', strtotime($givendate. ' + 30 days'));

option 3:
        $number = cal_days_in_month(CAL_GREGORIAN, date('m', strtotime($givendate)), date('Y', strtotime($givendate)));
        $date3 = date('Y-m-d', strtotime($date2. ' + '.$number.' days'));

您可以使用 DateTime 类和 DateTime::add() 方法:

strtotime您可以在 2012 年 4 月必须到达的任何输入上简单地使用该函数,然后应用dateandstrtotime增量周期为“+1 个月”。

$x = strtotime($t);
$n = date("M Y",strtotime("+1 month",$x));
echo $n; 

以下是 PHP 手册中的相关部分:

此解决方案解决了将任意时间量增加到时间值的附加问题。

嗨除了他们的回答。我认为,如果您只想根据当前日期获得下个月,这就是我的解决方案。

$today = date("Y-m-01");

$sNextMonth = (int)date("m",strtotime($today." +1 months") );

请注意,我不断将日期定义为 01,以便我们可以安全地获得下个月。如果那是日期(“Ymd”);而当天是 31 它将失败。

希望这可以帮助。

日期差异

$date1 = '2017-01-20';
$date2 = '2019-01-20';

$ts1 = strtotime($date1);
$ts2 = strtotime($date2);

$year1 = date('Y', $ts1);
$year2 = date('Y', $ts2);

$month1 = date('m', $ts1);
$month2 = date('m', $ts2);

echo $joining_months = (($year2 - $year1) * 12) + ($month2 - $month1);

由于我们知道 strtotime(+1 月) 总是增加 30 天,如果日期以 31、30 或 29 天结束,并且如果您仍想留在下个月的最后一天,则可能会出现一些问题。

所以我写了这个复杂的脚本来解决这个问题并进行调整,以便您可以增加所有类型的格式,如年、月、日、小时、分钟和秒。


function seetime($datetime, $p = '+', $i, $m = 'M', $f = 'Y-m-d H:i:s')
{
    
    /* 
    $datetime needs to be in format of YYYY-MM-DD HH:II:SS but hours, minutes and seconds are not required
    $p can only be "+" to increse or "-" to decrese
    $i is the amount you want to change
    $m is the type you want to change
    
    Allowed types:
    Y = Year
    M = Months
    D = Days
    W = Weeks
    H = Hours
    I = Minutes
    S = Seconds
    
    $f is the datetime format you want the result to be returned in
    
    */
    $validator_y = substr($datetime,0,4);
    $validator_m = substr($datetime,5,2);
    $validator_d = substr($datetime,8,2);
    
    if(checkdate($validator_m, $validator_d, $validator_y))
    {
        $datetime = date('Y-m-d H:i:s', strtotime($datetime));
        #$p = either "+" to add or "-" to subtract
        if($p == '+' || $p == '-')
        {
            if(is_int($i))
            {
