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 $date2="2021-11-16";//结束日期 for ($me=0;$me<=diffBetweenTwoDays($date1, $date2);$me++){ $riqi=date("Y-m-d",(strtotime($date1)+86400*$me));//计算此时的日期 $sql = "select * from mdaima where shijian='" . $riqi . "' limit 1 "; 代码段...
以上可以通过指定的日期范围,循环按天输出日期,用于做按天输出结果的查询。
