PHP |每隔一年

Question

我需要一个php脚本，它从给定的开始日期变量每隔一年执行一次任务。

示例：

$start_year = 2011 and $current_year = 2016 => don't perform task
$start_year = 2012 and $current_year = 2016 => perform task
$start_year = 2013 and $current_year = 2016 => don't perform task
$start_year = 2014 and $current_year = 2016 => perform task
$start_year = 2015 and $current_year = 2016 => don't perform task

如何检查当前年份是否在开始日期之后的每隔一年的间隔内？

Answer 1

将开始年份减去当前年份并检查其是偶数还是奇数。
