Re: splitting array values

[bobn]

First it sounds like you don't really know what is in $score[0] (note not @score[0], though that may work). To get around this,

use Data::Dumper;
print Dumper(\@score);

This will tell you what is actually in @score, where the first element will be $score[0].

Also, an array doesn't really contain another array. arrays can only contain scalars, though one type of scalar is a refrence, which can be thought of as a pointer to another array. If $score[0] is such a reference to an array, the correct notation is:

@sorted= reverse sort { $a <=> $b } @{$score[0]};

This properly de-references the referance to feed an array into the sort.

The code that creates the array is this:

while( ($key, $value) = each %rank ) {
    $rank = $rank . " " . $key;
    }

Also when I print print $score[0]; it still gives me all the contents of the array. Thanks

It looks like your making one long string in $rank, the equivalent of:$rank .= " " . $key; I'm guessing that your array has one element with one long string in it, so it looks like it's not sorted.

If you just want to get a sorted list of the keys, you can do:

@sorted = sort { $b <=> $a } keys %rank;

Notice you don't have to do a reverse, you can just change the sense of the comparison.

I tried sorting the keys like you said VSarkiss, but it still doesn't change the order when I sort them, or when I reverse them either.

thanks
