Perl – Sort associative array by value

Posted on July 8, 2009 by admin in Misc

Here’s an alpha sort of the values of the associative array named “myarray”: foreach my $key (sort {$myarray{$a} cmp $myarray{$b}} keys %myarray) { print “$key : ” . $myarray{$key} . “\n”; }; And here’s the same sort numerically: foreach my $key (sort {$myarray{$a} $myarray{$b}} keys %myarray) { print “$key : ” . $myarray{$key} . “\n”; [...]

Here’s an alpha sort of the values of the associative array named “myarray”:

foreach my $key (sort {$myarray{$a} cmp $myarray{$b}} keys %myarray) {
        print "$key : " . $myarray{$key} . "\n";
};

And here’s the same sort numerically:

foreach my $key (sort {$myarray{$a} <=> $myarray{$b}} keys %myarray) {
        print "$key : " . $myarray{$key} . "\n";
};

And if you want numeric descending:

foreach my $key (sort {$myarray{$b} <=> $myarray{$a}} keys %myarray) {
        print "$key : " . $myarray{$key} . "\n";
};
