Re: Numerical refs to assoc array suddenly "undefined offset"??

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. ----- Original Message ----- From: "CC Zona" <cczona@nospam.invalid> To: <php-general@lists.php.net> Sent: 2001. június 29. 19:12 Subject: [PHP] Numerical refs to assoc array suddenly "undefined offset"?? > This is weird.
