Or if you are truly only looking to get rid of "-": 
my $foo = '123-4567';
$foo =~ tr/-//d;  # tr is specifically for the replacement
                  # of single characters, the "d" tells it
                  # to remove any characters for which
                  # is no translation provided.
print $foo;
