Re: how do i sort hash by key numerically

[Jouke]

This would do the trick:

#!/usr/bin/perl -w
%hash=( 89=>3, 45=>2, 1 =>5, 40=>3);
foreach (sort { $a <=> $b } keys(%hash) )
{
    print "key: $_ value: $hash{$_}\n"
}

Are you sure that this doesn't sort typographically rather than numerically. I think the {$a<=>$b} block cited by arhuman is necessary here.
