Hi, I am working on the code of a former employee and I don't understand what this $arr['N']['#'] refers to. I know it is a multidimensional associative array but the # i don't what this means.
it's a string ... used as the (associative) key to an array. the item you mention probably contains an id or number (because '#' is sometimes used to mean that), try this: var_dump($arr['N']['#']); '#' is just a string, it could be anything: 'A', 'B', 'my_array_key', 'even a complete sentence', these are all valid associative array keys.
Thank you
