商業周

Question

我需要一個函數在PHP中，將計算一個給定的日期範圍內的特定格式的商業周。 實施例：

的startDate = 2009年2月3日

結束日期= 31-12-2010

3月2日至六日

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

四月六日至10日

等等...

Answer 1

這不是直接的答案 - 它是用Perl編寫的（和Per​​l都有自己的一些怪癖在這方面）。但是，我認爲它確實產生了所需的輸出。

#!/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"; 
} 

編輯：修復範圍0..11中的月份數字打印爲01..12。也改變年的處理。

使用星期一和星期五的正午，否則只能處理幾天，我可以忽略冬季和夏季（標準時間和夏令時）之間切換的問題。

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)
