in reply to Processing a multiple="multiple" <select>

There is nothing wrong with not using the CGI module, but it has done most of the work for you.

As far as your code, $payload =~ tr/+/ /; should really use a regex to detect multiple parameters, and an assignment to an array. It's going to take additional logic to handle the contents of your payload when the results are not a SCALAR type, as in multiple select results.

    Is there any benefit to using s///g over tr///, in this context?

    I figured that tr/// would be less "expensive" since it's designed to only do character matching.

      Since you brought it up, 'sed' style matching is too heavy. All you want to do is detect the situation of multiple responses. 

      if ($payload =~ /+/) {
  # process as list
}
