I saw that you could do this with a hash array but was looking for just a regex solution if possible.

The left side is the regex, the right side is perl variable interpolation, and if you use the /e flag, its perl code. so 

$_ = "123";
s/(.)/ my $r = " LEFT "; if($1 eq '1'){ $r = " one " } $r /eg;
print "$_\n";
__END__
 one  LEFT  LEFT
