Hi Monks,

I got two arrays, containing each one, four random digits ( from 0 to 5).
I would like to compare both of them in order to have:

1.)How many digits are in the same positions ( same index )
2.)How many digits are in different positions.

Ex.
Array_one 2 1 3 5
Array_two 2 3 1 0

One element ( 2 ) is in the same position ( index 0 ).
Two elements ( 3,1 ) in different position.

The first one, I can solve with a for/foreach loop

$match = 0;
for $i = 0; i < 4; $i++
$match++ if $array_one[$i] == $array_two[$i]

while the second one.....

Thanks
Claudio
