格式化日期:: Manip的Delta到天 [英] Formatting Date::Manip's Delta to days

问题描述

我有这个例程，

我想保存这个增量来计算从到之间的每一天之间的日子
I有二维数组，我只需要工作日。

I want to save that delta to count the days between all to and from days in the from-to pairs I have in the 2 dimensional array, I just need the workdays.

说出

$date_from = 2012-02-09;
$date_to = 2012-02-13;
$delta_string = 4

sub calc_usage {
    use Date::Manip::Date;

    my $date_from;
    my $date_to;
    my $delta;

    my $i;
    for $i (0 .. $#DATE_HOLDER) {
        $date_from = new Date::Manip::Date;
        $date_to = new Date::Manip::Date;

        $date_from->parse($DATE_HOLDER[$i][0]);
        $date_to->parse($DATE_HOLDER[$i][1]);

        $delta = $date_from->calc($date_to, "business");

    }

}

推荐答案

要检索增量值，您必须使用以下内容：

To retrieve the delta values, you have to use the folllowing:

my @val = $delta->value();

其中包含7个元素的数组：

wich gives an array of 7 elements where:

$val[0]   holds years
$val[1]   holds months
$val[2]   holds weeks
$val[3]   holds days
$val[4]   holds hours
$val[5]   holds minutes
$val[6]   holds seconds

您还可以在标量环境中使用它：

you can also use it in scalar context:

my $val = $delta->value();

w给出一个具有相同7个元素冒号分隔符的字符串：

wich gives a string with the same 7 elements colon separated:

years:months:weeks:days:hours:minutes:seconds
