sort hash values which is an array

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I have a hash whose value is an anonymous array

#key => id,start,end
%hash ={ key1 => id1,2009/07/20-12-00-00-00,2009/07/20-15-            
+      00-00
         key1 => id2,2009/07/20-15-10-00,
         key2 => id1,2009/07/21-12-00-00-00,
      };

If you write `%hash = { ... }` the outcome will not be what you expect. `use strict: use warnings` will guard you against such mistakes. Use `(...)` instead of `{...}`.	[reply] [d/l] [select]

Well, how to sort on an array element is a FAQ. But judging from you example, giving you the FAQ answer will just cause you to come with a followup question, as your example only has one array which actually has an end date, and a poorly formatted one as well. Note BTW, that your example isn't valid code. It misses quotes, and arrayref delimiters. I'd say, either read the FAQ, or format your real question.	[reply]
