in reply to Trying to make a string generated like google

my @sorted_phases = sort { $b->{count} <=> $a->{count} }
                      values %$strings;

You'll then have an array of your hashes ordered by the "count" value. The ones with the highest count will be at the start of the array.

    OMG - your a star! I've been trying to get something like that to work for ages, and you did it in one line - thanks, it doesn't *exactly* what I need :)

    Cheers

    Hi,

    I'm trying to do something a bit more complex now: 

        my @sorted_phrases = sort { $b->{sort_number} <=> $a->{sort_number
+}, $b->{count} <=> $a->{count}  }
                      values %$strings;

    ..instead of just: 

        my @sorted_phrases = sort { $b->{count} <=> $a->{count}  }
                      values %$strings;

    Basically, what I need to do - is :

    1) Sort by the value "count" as they were done before
    2) If the 2nd array element has a value of "0" for "count", then it will order them by sort_number thereafter.

    I've tried all kinda things - including this messy bit of code - but I can't seem to get it working :( 

        my @sorted_phrases_2;
#    my $i = 0;
    foreach (my $i = 0; $i <= $#sorted_phrases; $i++) {

        local $_ = $sorted_phrases[$i];

        if ($i == 1) {

            print "BLA BLA XXX - \"$_->{count}\" " . Dumper($_);

            if ($_->{count} < 1) {
    
                my $chosen_id_now = $sorted_phrases[0]->{sort_number} 
++ 1;

                print qq|<br />Current sort was: $sorted_phrases[0]->{
+sort_number} , and new one is $chosen_id_now <br />|;
    
                foreach my $tmp (@sorted_phrases) {
                    if ($tmp->{sort_number} == $chosen_id_now) {
                        push @sorted_phrases_2, $tmp;
                    }
                }

            }
        } else {
            push @sorted_phrases_2, $_;
        }
        
    }

    @sorted_phrases = @sorted_phrases_2;

    Thanks for any ideas - as I'm stumped :(

    Cheers

      I've just logged on for the first time for almost a year and saw your unanswered question. It's really quite simple.

      my @sorted_phrases = sort {
  $b->{count} <=> $a->{count}
    or
  $b->{sort_number} <=> $a->{sort_number}
} values %$strings;

      It's really worth reading the Perl FAQ. See How do I sort an array by (anything)?
