PHP计算日期间隔天数：
function diffBetweenTwoDays ($day1, $day2){ $second1 = strtotime($day1); $second2 = strtotime($day2); if ($second1 < $second2) { $tmp = $second2; $second2 = $second1; $second1 = $tmp; } return ($second1 - $second2) / 86400;}PHP指定日期范围循环输出日期示例：
$date1="2021-11-01";//开始日期$date2="2021-11-16";//结束日期$days =
diffBetweenTwoDays($date1, $date2);for ($me= 0;$me<=$days; $me++){ 代码段...}
