By using &$field instead of just $field - you reference each item in the $_POST array directly and apply the procedure to it, rather than a copy of it. |
Interesting, I always thought foreach worked on a copy of the array only. I found out that the references only work in PHP >= 5

This will set any missing fields to NULL |
Note: Using a NULL value will evaluate as not set.
