Need Help with loop function in PHP

[19]

Hello, I am working on a project currently,
and the loop function inside the code isnt working properly,
I have a submission for it tmrw, so I need your help.
This is the code:

"$date = strtotime($items['Ldate']);
                    while ($date < $Sdate) {
                    echo date('Y/m/d', $date). "<br />";
                    $date = strtotime("+1 day", $date);
                    }"

The while condition is not working here thats the main issue i can see
If interested please dm S U K I#3706
