Re: Using foreach to iterate through a hash in an array

my @bla = (%hash, %hash2); doesn't create an array of hashes, it flattens the hashes to key - value pairs, so @bla in fact contains

"00:20:00", "a", "10:00:00", "b", "00:00:00", "a",
[download]

etc. (in no particular order).

To create an array of hashes, use references:

my @bla = (\%hash, \%hash2);
[download]

You can then iterate with dereference

for (keys %{ $bla[0] }) {
[download]

or, in recent Perls,

for (keys $bla[0]->%*)
[download]

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

Oh ok thank you. It works and it seems as if I have skipped a few tutorial pages. I will have to take another look into it and thanks again.	[reply]

I have tried iterating with foreach and the hash itself `foreach (keys $hash){` `print $_ . "\n";` `}` So far so good ... Given the code you OPed, it's hard to imagine this would have done anything "good" unless `$hash`.was actually a hash reference. If this was the case, please be aware of this from the latest Perl documentation: Starting with Perl 5.14, an experimental feature allowed keys to take a scalar expression. This experiment has been deemed unsuccessful, and was removed as of Perl 5.24. This experimental ex-feature was also associated with values, each, push, pop and friends.
