Hi all,
Let me brief the basics of hash.
keys %hash; will return the keys available in Hash.
values %hash; will return the values available in Hash.
But Recently I met an Issue as follows :-
my %param;
foreach my $values ( sort values %user_details ) {
$param{user_name} = $values;
}
I will use the Above sorted user names to display in the web screen.
But suddenly I had a requirement like to get the keys of hash by using the hash values.
Is there a way to get the key of a hash using its values.
Because as per my understanding the keys of Hash can not be duplicate, Even if it is so there is no meaning in having that
$hash{1} = 'One';
$hash{1} = 'one';
# No use
can any one have Idea in getting this work ?

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).
