Re^3: Search for abcNUMBERdef, make it a variable, then do math?

The first part of the script is

if (length ($ENV{'QUERY_STRING'}) > 0){
      $buffer = $ENV{'QUERY_STRING'};
      @pairs = split(/&/, $buffer);
      foreach $pair (@pairs){
           ($name, $value) = split(/=/, $pair);
           $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg
+;
           $in{$name} = $value; 
      }
 }

my $id = param('id');

use LWP::Simple;
$id2 = get ("http://www.domain.com/stats.php?id=$id");

and Line 19 is use LWP::Simple;

`Prototype mismatch: sub main::head: none vs ($) at stats.cgi line 19` See CAVEAT in the LWP::Simple docs: Note that if you are using both LWP::Simple and the very popular CGI.pm module, you may be importing a head function from each module, producing a warning like "Prototype mismatch: sub main::head ($) vs none". Get around this problem by just not importing LWP::Simple's head function, like so: `use LWP::Simple qw(!head); use CGI qw(:standard); # then only CGI.pm defines a head()` [download] As for "The first part of the script is" part: why are you parsing the QUERY_STRING yourself, when you're using CGI.pm anyway — as the warning and your line `my $id = param('id')` indicates? CGI.pm does the parsing already, so you can just drop that code...	[reply] [d/l] [select]
