Re^2: Convert string to hash

just added the'\' and worked :)

foreach my $value (values $jsonhash{results} )
        {
                $temp{$value->{'certname'}} = \%$value;
        }

That works, but it is unnecessary, since `\` and `%` are complements, in a sense, and cancel each other out: `%` dereferences a hash reference (`$value`), i.e. gives you the hash it references; `\` then gives you a reference to this hash again. There's nothing wrong with doing it this way, but I encourage you to get a good grip on references (hash or not). You'll often encounter them in Perl, and nested data structures don't work without them at all.	[reply]

It's cheaper to throw away a `%` than to add a `\` ... Your solution is silly. Read perlreftut to find out why ... worth your time! The way forward always starts with a minimal test.	[reply] [d/l] [select]
