Re: Re: Getting information from an array of hashes

in reply to Re: Getting information from an array of hashes
in thread Getting information from an array of hashes

If I put in a line that says

print "$diary_data[0]\n";

it prints:

ARRAY(0x3bfda0)

If I change the print slightly, like this:

print "@{$diary_data[0]}\n";

This is what I get:

HASH(0x3bfdc4)

Then if I try

print "%{$diary_data[0]}\n";

it gives me:

%{ARRAY(0x3bfdd0)}

I don't think I'm understanding this correctly. The first example looks to me like a scalar reference, pulling data out of an array; but since the array contains hashes, then how does this get pulled out? Is this "ARRAY(0x3bfda0)" line an internal reference to how Perl remembers something?

Anyway, I'm off to read perldsc for a while.
