You can use Storable
use Storable qw(nfreeze thaw);
$scalar = nfreeze(\%hash);
%hash_copy = %{ thaw($scalar) };
If you need to have hash with keys - usenames and values as data structure (not scalar) you can use tie... for binding to sql database use eg. Tie::RDBM module. Example from docs:
use Tie::RDBM;
tie %h,Tie::RDBM,'mysql:test',{table=>'Demo',create=>1,autocommit=>0};
$h{'key1'} = 'Some data here';
$h{'key2'} = 42;
$h{'key3'} = { complex=>['data','structure','here'],works=>'true' };
$h{'key4'} = new Foobar('Objects work too');
print $h{'key3'}->{complex}->[0];
tied(%h)->commit;
untie %h;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
