Hash Variables

[Batiatus]

Hi, I am new to CGI and have a question about hash variables.

What is the purpose of using them over array variables? The only difference I can see is that the key for an array is just the 0, 1, 2..., and so on, and you can specify the key for a hash. Why would you really need to assign a different key?

Hi

I think you are talking about Perl. Which belongs to forum219 ( Perl ).

Why need hash ? Look at the [tt]%ENV[/tt] and try to store its values in an array. Then search it and sort it. Then you will know why.
