I have several arrays of the same length where each indexed element is related i.e. $array_a[0] is linked to $array_b[0] etc. and the same for all other elements / arrays.
Then evidence suggests that the data contained in those array could be better organized in a more complex structure reflecting their internal logical relationships, e.g. a so called AoA or an AoH. For example you may have
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
my @array=([2, 'fred'],
[1, 'bob'],
[4, 'john'],
[3, 'peter']);
print Dumper [ sort {$a->[0] <=> $b->[0]} @array ];
__END__
=>
$VAR1 = [
[
1,
'bob'
],
[
2,
'fred'
],
[
3,
'peter'
],
[
4,
'john'
]
];

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).
