I've got 3 elements in each array1 and array2. They act as tables in a database with a one to many relationship. There are unique values in array1 and duplicate values in array2. So for every $id in array1 there are multiple $id's in array2.
Now that I've got the arrays defined and I can get the values by doing

foreach (@array1) {
   ($id,$name,$ref) = split( /,/, $_);
}

and 
foreach (@array2) {
    ($id,$name,$ref) = split( /,/, $_);
}

[download]

I want to print out $id once from array1 and the number of times $id appears in array2. Once I do this I can massage the data as needed.

Any kind advice or direction is welcomed.
