如何使用PHP找到两个日期之间的天数?
当前回答
$diff = strtotime('2019-11-25') - strtotime('2019-11-10');
echo abs(round($diff / 86400));

如果你正在使用MySql
function daysSince($date, $date2){
$q = "SELECT DATEDIFF('$date','$date2') AS days;";
$result = execQ($q);
$row = mysql_fetch_array($result,MYSQL_BOTH);
return ($row[0]);
}
function execQ($q){
$result = mysql_query( $q);
if(!$result){echo ('Database error execQ' . mysql_error());echo $q;}
return $result;
}
这段代码为我工作,并用PHP 8版本测试:
function numberOfDays($startDate, $endDate)
{
//1) converting dates to timestamps
$startSeconds = strtotime($startDate);
$endSeconds = strtotime($endDate);
//2) Calculating the difference in timestamps
$diffSeconds = $startSeconds - $endSeconds;
//3) converting timestamps to days
$days=round($diffSeconds / 86400);
/* note :
1 day = 24 hours
24 * 60 * 60 = 86400 seconds
*/
//4) printing the number of days
printf("Difference between two dates: ". abs($days) . " Days ");
return abs($days);
}
$early_start_date = date2sql($_POST['early_leave_date']);
$date = new DateTime($early_start_date);
$date->modify('+1 day');
$date_a = new DateTime($early_start_date . ' ' . $_POST['start_hr'] . ':' . $_POST['start_mm']);
$date_b = new DateTime($date->format('Y-m-d') . ' ' . $_POST['end_hr'] . ':' . $_POST['end_mm']);
$interval = date_diff($date_a, $date_b);
$time = $interval->format('%h:%i');
$parsed = date_parse($time);
$seconds = $parsed['hour'] * 3600 + $parsed['minute'] * 60;
// display_error($seconds);
$second3 = $employee_information['shift'] * 60 * 60;
if ($second3 < $seconds)
display_error(_('Leave time can not be greater than shift time.Please try again........'));
set_focus('start_hr');
set_focus('end_hr');
return FALSE;
}
如果你想在开始日期和结束日期之间重复所有的日子,我想出了这个:
$startdatum = $_POST['start']; // starting date
$einddatum = $_POST['eind']; // end date
$now = strtotime($startdatum);
$your_date = strtotime($einddatum);
$datediff = $your_date - $now;
$number = floor($datediff/(60*60*24));
for($i=0;$i <= $number; $i++)
{
echo date('d-m-Y' ,strtotime("+".$i." day"))."<br>";
}
如果你有以秒为单位的时间(即unix时间戳),那么你可以简单地减去时间并除以86400(秒/天)
