    this worked good:

    date_default_timezone_set('Asia/tehran');
$timeStamp = 1682936936; //2023-5-1 13:58 for example
$nowTime = strtotime(date("Y-m-d H:i")); // edit: delete secend

$oneDayBefore = strtotime("-1 day",$timeStamp);
$threeDaysAfter = strtotime("+3 days",$timeStamp);

if($nowTime >= $oneDayBefore && $nowTime <= $threeDaysAfter){
    echo "yes";
}
else{
    echo "no";
}

    i add default timezone and remove second from now time and add = to < or > now work and results is true for every timestamp

    Specific problem with your code as-written:

    strtotime() takes a date string, but you’re giving it a timestamp. You need to feed it $nowTime instead, eg:

    $oneDayBefore = strtotime("-1 day",$nowTime);
$threeDaysAfter = strtotime("+3 days",$nowTime);

    Also, if you use the DateTime functions instead you don’t have to convert back and forth between strings and rely on functions just magically knowing what your date format is:

    $timeStamp = 1682936936;

$now   = (new DateTime())->setTimestamp($timeStamp);
$begin = (clone $now)->sub(new DateInterval('P1D'));
$end   = (clone $now)->add(new DateInterval('P3D'));

if( $now > $begin && $now < $end){
    echo "yes";
}
else{
    echo "no";
}
echo PHP_EOL;

var_dump(
    $now->format('U'),
    $now->format('c'),
    $begin->format('U'),
    $begin->format('c'),
    $end->format('U'),
    $end->format('c')
);

    Output:

    yes
string(10) "1682936936"
string(25) "2023-05-01T12:28:56+02:00"
string(10) "1682850536"
string(25) "2023-04-30T12:28:56+02:00"
string(10) "1683196136"
string(25) "2023-05-04T12:28:56+02:00"

    DateTime object allow far more control than the old utility functions like strtotime(), especially if you need to do anything with timezones.
