You can modify a PHP DateTime object, it's fairly simple to add or subtract date intervals, this is the first example in the manual.
您可以修改 PHP DateTime 对象，添加或减去日期间隔相当简单，这是手册中的第一个示例。
<?php
$date = new DateTime('2006-12-12');
$date->modify('+1 day');
echo $date->format('Y-m-d');
?>

$today = strtotime("$hour:00:00");
$yesterday = strtotime("-1 day", $today);
