I am fairly new to Perl but I use the following code to get the Query String. It has not failed me yet:

#!/usr/bin/perl
use Fcntl;

print "Content-type:text/html\n\n";
print "hello world";

if ($ENV{'REQUEST_METHOD'} eq "GET") {

    $request = $ENV{'QUERY_STRING'};

} elsif ($ENV{'REQUEST_METHOD'} eq "POST") {
    read(STDIN, $request,$ENV{'CONTENT_LENGTH'}) 
        || die "Could not get query\n";

} 

@parameter_list = split(/&/,$request); 
foreach (@parameter_list) {                            # split each va
+riable=value pair
    ($name, $value) = split(/=/);
    $name =~ s/\+/ /g;                                 # replace "+" w
+ith  spaces
    $name =~ s/%([0-9A-F][0-9A-F])/pack("c",hex($1))/ge;
                                                       # replace %nn w
+ith characters
    $value =~ s/\+/ /g;                                # repeat for th
+e value ...
    $name =~ s/%([0-9A-F][0-9A-F])/pack("c",hex($1))/ge;
    if (!(defined $passed{$name})) {
        $passed{$name} = $value;
    } else {
        $passed{$name} .= ":$value";
    }
}

I found this on a webpage so I can't take credit for it. I will post a link as soon as I can find it again.

It makes getting the query string values rather simple, just use $passed('myVar') if in a string or else $passed("myVar").
