push @{ $no_name_found { $user_name } }, $city;
The value associated with the key is an
array reference, and so
my $value = $result->{$key};
print "User Name = $key - City: $value\n";
will output something that looks like
User Name = User - City: ARRAY(0x3eafa1c)
You might get something closer to what you expect with
my $value = $result->{$key};
local $" = ', ';
print "User Name = $key - City: @$value\n";
or
my $value = $result->{$key};
print "User Name = $key - City: ", join(', ', @$value), "\n";
or something similar.

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).
