PHP problem when comparing time

Hi, I have a weirder problem when using "date" for e.g

if (date('H') >= 23 || date('H') < 9) {
	not works
	}

If I have time longer than 23 pm and less than 9 in if it should show me something Not working But if I put more

if (date('H') >= 1 || date('H') < 9) {
		works
	}

If I put it after 00 1 AM it works I want something to be turned off between 11pm and 9am, but that's the problem when I turn 23

Do you have any idea why it doesn't work?

using Carbon, I dont get the problem you are reporting.

function checkActive(int $hour): string
{
    if ($hour >= 23 || $hour < 9) {
        return 'inactive';
    }
    return 'active';
}

        $hours = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23];

        foreach ($hours as $hour){
            dump(checkActive($hour));
        }

outputs

"inactive"
"inactive"
"inactive"
"inactive"
"inactive"
"inactive"
"inactive"
"inactive"
"inactive"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"active"
"inactive"

i set hour using:

    $hour = \Carbon\Carbon::now()->format('H');

Note that date('H') returns a string and not an integer. And also note that it might be possible that date() might be in a different timezone than you expect it to be.

You should be able to easily debug this yourself by printing the results or adding it to your log.
