To all,

I have a string of thirty digits that I need to insert dashes after every 5 digits, and then a <br> after the 15th digit, as in:

012345678901234567890123456789 ==>
01234-56789-01234<br>56789-01234-56789

This is what I've come up with. What are some other alternatives to this regex? 
#!/perl/bin/perl -w

use strict;

my $s = "012345678901234567890123456789";
print $s, "\n";

$s =~ s/(\d{5})(\d{5})(\d{5})(\d{5})(\d{5})(\d{5})/$1-$2-$3<br>$4-$5-$
+6/;
print $s, "\n";

Where do you want *them* to go today?
