A faster way:

my @array = qw(name John number 7 status unknown); my $i = -2; my $x = $#array - 1; my $str = ''; while (1) { if ($i + 3 < $x) { $str .= $array[$i += 2] . '=' . $array[$i + 1] . '&'; } else { $str .= $i + 3 == $x ? $array[-3] . '=' . $array[-2] . '&' . $arra +y[-1] : $i + 2 == $x ? $array[-2] . '=' . $array[-1] : $array[-1]; last; } } print "$str\n";
