如何在php中从复活节日期中减去一周

// 获取当前年份的复活节日期
$easterDate = date("Y-m-d", easter_date());

// 将复活节日期转换为时间戳
$easterTimestamp = strtotime($easterDate);

// 减去一周的时间戳值
$oneWeekAgoTimestamp = $easterTimestamp - (7 * 24 * 60 * 60);

// 将时间戳转换为日期格式
$oneWeekAgoDate = date("Y-m-d", $oneWeekAgoTimestamp);

echo "复活节日期减去一周的结果是：" . $oneWeekAgoDate;
