Extended array_diff_assoc noticing change from/to NULL values
It behaves almost the same way as array_diff_assoc except for NULL values: if
one of the values is not NULL - change is detected. It is useful in situation
where one value is strval('') ant other is strval(null) - in string comparing
methods this results as EQUAL, while it is not.
@param array $array1 Base array
@param array $array2 Corresponding array checked for equality
@return array Difference as array with array(keys => values) from input array
where match was not found.
