如何使用日期时间差异：PHP

Question

我在函数中使用 DateTime diff 函数，为此我需要计算一组日期之间的秒数。我有这个功能：

public function CanBet($bettilltime, $bettilldate, $betsettime, $betsetdate, $amount) {
    $can_bet = true;
    $bettilltime = new DateTime(date("H:i:s", strtotime($bettilltime)));
    $bettilldate = new DateTime(date("Y-m-d", strtotime($bettilldate)));

    $betsettime = new DateTime(date("H:i:s", strtotime("H:i:s", $betsettime)));
    $betsetdate = new DateTime(date("Y-m-d", strtotime("Y-m-d", $betsetdate)));

    $timeDiff = $betsettime->diff($bettilltime);
    return print $timeDiff->s;
    $dateDiff = $betsetdate->diff($bettilldate);
    return print $dateDiff->s;
    if ($this->GetUserBalance() > $amount) {
        if ($timeDiff->s >= 0) {
            if ($dateDiff->s >= 0) {
                $can_bet = true;
            }
            else {
                $can_bet = false;
            }
        }
        else {
            $can_bet = false;
        }
    }
    else {
        $can_bet = false;
    }

    return $can_bet = false;
}

我正在 return 打印 $....Diff 以检查它们是否是一个值，但是这些总是 return 0。我尝试使用 ->d | ->m |->y | ->i | ->s | ->h | ->days（我知道这些值不会 return 秒，我用它们来测试）以便从这些值中获取要打印的值，但是，它不显示 0 以外的值，我是什么这里做错了吗？

注
我在这里将最终的 return 设置为 false 以允许我能够停止使用它的功能，我想将我的值保留在原处。

只需进行简单的 DateTime 对象比较，这应该可行（并且还消除了很多虚假的 else 检查。

public function CanBet($bettilltime, $bettilldate, $betsettime, $betsetdate, $amount) {
    $can_bet = false;

    $bettilltime = new DateTime($bettilltime);
    $bettilldate = new DateTime($bettilldate);

    $betsettime = new DateTime($betsettime);
    $betsetdate = new DateTime($betsetdate); 

    if ($this->GetUserBalance() > $amount) {
        if ($betsettime <= $bettilltime) {
            if ($betsetdate <= $bettilldate) {
                $can_bet = true;
            }
        }
    }

    return $can_bet;
}

但是

public function CanBet($bettilltime, $bettilldate, $betsettime, $betsetdate, $amount) {
    $can_bet = false;

    $bettilltime = new DateTime($bettilldate.' '.$bettilltime);
    $betsettime = new DateTime($betsetdate.' '.$betsettime);

    if ($this->GetUserBalance() > $amount) {
        $can_bet = $betsettime <= $bettilltime;
    }

    return $can_bet;
}

将 return 没有日期和时间的无意义分割的完全相同的结果

更简单：

public function CanBet($bettilltime, $bettilldate, $betsettime, $betsetdate, $amount) {
    $bettilltime = new DateTime($bettilldate.' '.$bettilltime);
    $betsettime = new DateTime($betsetdate.' '.$betsettime);

    if ($this->GetUserBalance() > $amount) {
        return $betsettime <= $bettilltime;
    }

    return false;
}
