I'm affraid I do not understand? "array_diff" and "array_diff_key"
do not register anything and they do not search for anything. They
"calculate" and return differences between arrays.

$error will not return anything. It contains entries which are
in the array contained in first argument of "array_diff_key"
which do not have any equivalent entry in array contained in
second argument.
