Re: [PHP] Numerical refs to assoc array suddenly "undefined offset"?? From: Gyozo Papp (pgerzson <email protected>)

This should not work - at least in that way you'd like.
These arrays are associative ones and so, numerical indices are not specified.
use foreach ($arr as $key => $val) or list ($key, $val) = each($arr) to traverse an array properly.
