hash and array 3

[simanek]

Does anyone know of a method to assign all of the values of a hash into an array without knowing the keys of the hash? Thanks.

foreach $value (values %yourhash) {
push @yourarray,$value;

Here's a quicker way:

@array = values %hash;

The values function already returns a list, so there's no need to step thru the list and push the values into the array, just assign all of them to the array at once.

Exactly what I was thinking, tsdragon. And, if you already have an array and want to push the values of the hash onto it, there's nothing stating that you have to push one element at a time, so

push @array,values %hash;

...works just fine.

Good thinking sophisticate. I thought about adding a caveat to my example warning that it would completely replace the array rather than adding to it. You solved that problem.

And, if you want the hash values sorted into the array:

@array = sort values %hash;
