PHP 判断几秒前，几分钟，几小时前最多判断6天前

$time = strtotime("2021-02-17 19:04:14");
echo ReckonTime($time);

function ReckonTime($time)
{
    $NowTime = time();
    if($time > $NowTime){ return false; }
    $TimePoor = $NowTime - $time;
    if ($TimePoor == 0) {
        $str = '一眨眼之间';
    } else if ($TimePoor  0) {
        $str = $TimePoor . '秒之前';
    } else if ($TimePoor >= 60 && $TimePoor  60 * 60 && $TimePoor  3600 * 24 && $TimePoor  3600 * 24 * 7) {
        $str = date("Y-m-d", $time);
    }
    return $str;
}

6天前
