Looks to me like you aren't really that interested in the order of the values in @owner_grouprights and instead just want to be able to easily check whether specific values are present or not. This is not a job for an array. You want a hash:

#!/usr/bin/env perl    

use strict;
use warnings;
use 5.010;

# Don't really need the qw, since these are numbers, but the original
# code explicitly made them strings, so whatever.
my @owner_grouprights = qw( 11 14 );

my %rights_hash;
$rights_hash{$_}++ for @owner_grouprights;

if (exists $rights_hash{11}) {
  say "test3";
}

for (4 .. 12) {
  if (exists $rights_hash{$_}) {
    say "test2";
    last; # avoid duplicate messages if more than one is present
  }
}

# Or, alternately:

if (grep /4|5|6|7|8|9|10|11|12/, keys %rights_hash) {
  say "test2 alt";
}

# Note, though, that the two alternatives are not equivalent.  The
# first (if exists) only returns exact matches, while the second
# (grep) also finds substring matches. So, e.g., 114 would match the
# 'grep' version, but not the 'if exists' version. Adding begin/
# end-of-string anchors (^/$ or \A/\Z) to the 'grep' version's regex
# will disallow partial matches if you want that, but don't want the
# explicit 'for' loop.

my $owner_grouprights = join( ' ', sort keys %rights_hash);

my @testarr = (4 .. 12);
for my $tst (@testarr) {
  if (exists $rights_hash{$tst}) {
    say "$tst hit!";
  } else {
    say "$tst miss";
  }
}

• 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).
