$ payment_date是我想减去1个月的日期。我该怎么办？我只想从上个月付款

Answer 1

容易！

<?php

$date = new DateTime();
$date->modify('-1 month');
echo $date->format('Y-m-d H:i:s');

在此处查看https://3v4l.org/UWaGY

您还可以将日期字符串作为构造函数提供。 new DateTime('2014-09-18');

Answer 2

@LEARNER尝试这样，在这里检查输出和代码https://eval.in/806939：

<?php
//suppose that date is 2017/05/29
$yourDate = strtotime('2017/05/29 -1 month'); // substract 1 month from that date and converting it into timestamp
$desiredDate = date("Y-m-d", $yourDate);
echo $desiredDate;
?>

如何从任何日期减去1个月并从数据库中获取该月的值
