有任何想法吗?
即使指导我阅读教程也会受到赞赏.
问候,

或者,如果你是疯了,想要在正则表达式中验证(需要Perl 5.10):
@H_502_11@#!/usr/bin/env perl5.10.0use strict;use warnings;my @mon = qw/null JAN FEB MAR APR MAY JUN Jul AUG SEP OCT NOV DEC/;my $d = join '',@ARGV;# only valIDates between 1600 and 9999# because of calendar weirdness prior to 1600 $d =~ s/ ^ (?: # non-leap years and everything but 29th of Feb in leap years (?: 1[6-9] (?<y> [0-9]{2}) | [2-9][0-9] (?<y> [0-9]{2}) ) (?: #any month 1st through 28th (?: (?<m> 0[1-9] | 1[0-2]) (?<d> 0[0-9] | 1[0-9] | 2[0-8]) ) | #or 30th of any month but 2 (?: (?<m>0[13-9] | 1[0-2]) (?<d> 30) ) | # or 31st of 1,3,5,7,8,10,or 12 (?: (?<m>0[13578] | 1[02]) (?<d> 31) ) ) | # or 29th of Feb in leap years (?: (?: #centurIEs divisible by 4 minus the ones divisible by 100 16 | [2468][048] | [3579][26] ) (?<y> 00) | #or non-centurIEs divisible by 4 (?: 1[6-9] | [2-9][0-9] ) (?<y> 0[48] | [2468][048] | [13579][26] ) ) (?<m> 02) (?<d> 29) ) $/$+{y}-$mon[$+{m}]-$+{d}/x or dIE "invalID date: $d";print "date is Now $d\n"; 总结以上是内存溢出为你收集整理的如何在不导入外部模块的情况下在Perl中转换日期格式?全部内容,希望文章能够帮你解决如何在不导入外部模块的情况下在Perl中转换日期格式?所遇到的程序开发问题。
