我正在尝试根据日期计算1-21天的天数价格。
$Sql = ' SELECT DISTINCT
a.property_id, a.date, a.minimum_stay,
a.maximum_stay,a.quantity,
a.arrival_allowed,a.departure_allowed,
p.duration, p.persons, p.amount,
p.extra_person_price, p.minimum_stay AS price_minimum_stay,
p.maximum_stay AS price_maximum_stay, p.weekdays,
p.period_till, p.period_from,
datediff(p.period_till, p.period_from) AS number_of_days
FROM availabilities AS a
JOIN prices AS p
ON a.property_id=p.property_id
WHERE a.minimum_stay >0
AND a.maximum_stay < 22
AND a.date >= p.period_from
AND a.date <= p.period_till
';
$Stm = $this->getEntityManager()->getConnection()->prepare($Sql);
$Stm->execute();
return $Stm->fetchAll(PDOConnection::FETCH_ASSOC);
public function CalculatePrice($persons, $extra_person_price, $date, $amount, $duration, $period_till, $period_from)
{
//loop through persons
foreach ($persons as $person) {
//calculate price for persons
if ($person > 1) {
$amount += $person * $extra_person_price;
}
//array to link parameters with database fields
$tmp = array(
"date" => $date,
"person" => $person,
"price_person" => number_format($amount / 100, 2, '.', ',')
);
//loop through $tmp an add value from 2 to 21 to day an add this to $tmp array with calculated value
//$x=$number_of_days;
//$days = (strtotime($period_till) - strtotime($period_from)) / (60 * 60 * 24);
for ($x = 1; $x <= 21; ++$x) {
if ($x >1) {
$tmp["day$x"] = $tmp["day".($x-1)] + number_format($amount / 100, 2, '.', ',');
//number_format(($amount * $x) / 100, 2, '.', ',');
} else {
$tmp["day$x"] = "0.00";
}
$price_per_person[] = $tmp;
}
return $price_per_person;
}
我也在计算人数的价格,但那部分是好的。现在我已经制作了一个for循环并存储了从1到21的数字,在function CalculatePrice
中查看我的第二个for循环。但这部分不好我需要根据日期来计算。例如:
大多数日子的定期价格是123欧元。比如9月3日那天花费250欧元,9月7日花费300欧元。所以,请说一个人想要停留5天,他到9月3日,所以计算将是:250 + 123 + 123 + 123 + 300 = 919欧元。
但我需要这个基于日期。我试过了period_from和period_til,但到目前为止还没有运气。有人可以提供一个示例或一些有用的提示我如何在for循环中执行此操作,就像我的第二个for循环一样。

我已根据理论T. Abdelmalek给了我这个问题。我制作了一个数组,并存储了每个日期的日期和价格。答案已被删除,我不知道如何标记为已解决

您可以像这样使用date_diff
:
First date = $leave->getLeaveFrom();
Second date = $leave->getLeaveTo();
$diff = date_diff($leave->getLeaveFrom(),$leave->getLeaveTo());
Results = var_dump($diff);
