note 19249 added to function.array-filter

Here's a good function to filter multidimensional arrays: <code> function array_filter_multi($input, $filter="", $keepMatches=true) { if (!is_array($input)) return ($input==$filter xor $keepMatches==false) ? $input : false; while (list ($key,$value) = @each($input)){ $res = array_filter_multi($value, $filter,$keepMatches); if ($res !== false) $out[$key] = $res; } return $out; } </code> Default behavior is to remove blanks from a multi-dimensional array, but you can filter out any string (arg #2) with a positive or negative filter (arg #3). -- http://www.php.net/manual/en/function.array-filter.php http://master.php.net/manage/user-notes.php?action=edit+19249 http://master.php.net/manage/user-notes.php?action=delete+19249 http://master.php.net/manage/user-notes.php?action=reject+19249
