Question

我需要一个php中的函数，它将在给定的日期范围内以特定格式计算商业周。例如：

startDate = 02-03-2009

endDate = 31-12-2010

3月2日至6日

3月9日至13日

3月16日至20日

3月23日至27日

3月30日 - 4月3日

4月6日 - 10日

依旧......

Answer 1

这不是直接答案 - 它是用Perl编写的（Perl在这方面有一些自己的怪癖）。但是，我认为它会产生所需的输出。

#!/bin/perl -w
#
# Given two Unix-style timestamps (smaller, larger), produce a range of weeks.
# SO 613337

use strict;
use POSIX;

my($t1) = $ARGV[0];
my($t2) = $ARGV[1];

# Split given times into pieces
my($sec1,$min1,$hour1,$mday1,$mon1,$year1,$wday1) = localtime($t1);
my($sec2,$min2,$hour2,$mday2,$mon2,$year2,$wday2) = localtime($t2);

# Determine midday on Monday for starting week.
# Determine midday on Friday for ending week.
# Saturday rounds backwards; Sunday rounds upwards.
my($t3) = mktime(0, 0, 12, $mday1 - ($wday1 - 1) + 0, $mon1, $year1);
my($t4) = mktime(0, 0, 12, $mday2 - ($wday2 - 1) + 5, $mon2, $year2);

my($sec3,$min3,$hour3,$mday3,$mon3,$year3,$wday3) = localtime($t3);
my($sec4,$min4,$hour4,$mday4,$mon4,$year4,$wday4) = localtime($t4);

print "t1 = %10d; %04d-%02d-%02d (%d)\n", $t1+1900, $year1, $mon1+1, $mday1, $wday1;
print "t2 = %10d; %04d-%02d-%02d (%d)\n", $t2+1900, $year2, $mon2+1, $mday2, $wday2;
print "t3 = %10d; %04d-%02d-%02d (%d)\n", $t3+1900, $year3, $mon3+1, $mday3, $wday3;
print "t4 = %10d; %04d-%02d-%02d (%d)\n", $t4+1900, $year4, $mon4+1, $mday4, $wday4;

use constant secs_per_week  => 24 * 3600 * 7;
use constant secs_to_friday => 24 * 3600 * 4;

for (my($t) = $t3; $t < $t4; $t += secs_per_week)
{
    my($mon) = strftime("%b %e", localtime($t));
    my($fri) = strftime("%b %e", localtime($t + secs_to_friday));
    my($ans) = "$mon - $fri";
    $ans =~ s/^(\w\w\w)\s+(\d+) - (\1)\s+(\d+)$/$1 $2-$4/;
    $ans =~ s/  +/ /g;
    print "$ans\n";
}

已编辑：修正0..11范围内的月份数字，打印为01..12。也改变了多年的处理。

使用星期一和星期五的正午，只处理几天，我可以忽略在冬季和夏季（标准和夏令时）之间切换的问题。

例如：

$ perl weekdays.pl 1234567890 1324567890
t1 = 1234567890; 2009-02-13 (5)
t2 = 1324567890; 2011-12-22 (4)
t3 = 1234209600; 2009-02-09 (1)
t4 = 1324756800; 2011-12-24 (6)
