try
${$array[1]}{'Item'} = $something;
The only way you can (safely) add a "hash" to an array (or inside another
hash) is to use a hash reference. Of course Perl gives you several ways to
do this :-)
You declare a hash REFERENCE like this:
$hashref = {
hashkey => 'hashvalue'
};
Note the { }, instead of ( )
To set an element of an array to a hashref, you can do
$array[1] = {
hashkey => 'hashvalue'
};
To change (or retrieve) the value in a hash, you can do (see perlref
manpage):
$$hashref{newkey} = 'newvalue';
OR
$hashref->{newkey} = 'newvalue';
Both of these mean the same thing:
$$hashref and $hashref-> mean 'dereference the reference $hashref'
{...} means 'expect the reference to be a reference to a hash'
You can substitute $hashref with $array[1] like this:
${$array[1]}{newkey} = 'newvalue';
OR
$array[1]->{newkey} = 'newvalue';
Note the braces { } in ${$array[1]}.
$$array[1] is interpreted as: $$array means dereference the reference
$array, and the [] means 'expect the reference $array to point to an array'.
No wonder you have a headache... I get a headache just writing this :-)
i.e.
# store a hash in the array @array
${$array[1]}{newkey} = 'newvalue';
print $array[1]->{newkey};
# store a hash in the array referenced by $arrayref
$$arrayref[1]{newkey2} = 'newvalue2';
print $$arrayref[1]{newkey2};
print $arrayref->[1]{newkey2};
Sticking to the -> notation is less prone to give headaches (though only
slightly).
Read the perlref manpage (about half a dozen times) until it all sinks in...
