A more efficient version might look something like this: 
my $select = param('select');
my $found;
foreach (@display_files) {
  if ($_ eq $select) {
    $found = 1;
    last;
  }
}

 ... or use List::Util and 
my $select = param('select');
my $found = List::Util::first { $_ eq $select } @display_files;
