Re: changing table fields value for all found in the list

Yes you have to have "&" in front of $photo.  This makes $photo a reference to the element in $photos instead of a copy.  If you don't have it then you will be modifying a copy of the array element and not the element itself.

See http://www.php.net/manual/en/language.references.php for a discussion of references in PHP.
