I am looking to run a foreach loop on my array where each element of that array is a hash. where my hash and array are established as below. 
 

push @mass_info, {"PID" => $PID,
    "IO" => \@IO};

I am trying 
foreach(@mass_info){
    print "$_{PID} \n";
}

[download]
This does not work but this does. 
$counter = 0;
foreach (@mass_info){
    print "$mass_info[$counter++]{PID}\n";
}

I would like to know how perl does this foreach loop the first way.

Thanks in advance.
