Try the Substitution Operatorby chromatic (Archbishop) |

my $count = ($string =~ s/(foo)/$1/g); will also do the trick. Benchmarking is left as an exercise for the discerning acolyte. The match operator (/foo/) only returns a boolean to indicate that it did or did not match. Our friend Mr. Substitution gives us more data. tr/// is probably much faster for simple substrings, not regex's.
