Re: pushing hash values to an array

[blazar]

#!/usr/local/bin/perl
use strict;
use warnings;
%h=('1', 'one', '2', 'two', '3', 'three');

Since you're under strict this won't even compile.

@arr=(1,2);

Ditto! (But I won't insist further.)

foreach $key(keys %h)
{
push(@arr,$h{$key});
}
print @arr;

Thus is correct.

foreach $key(keys %h)
{
push(@arr,$$h{$key});

This is not. Why do you expect $h{$key} to be a scalar reference?

print "@arr\n";
}

You probably want to print out of the loop. Be careful (also) when preparing test examples.

All in all I suspect (but it's hard to tell from your description of the problem) you be in a situation in which you have $href=\%h or the like, and then

push @arr, $href->{$key};

is the way to go.
