note 10092 added to Array Functions

i have code that reads: echo "<input type=hidden name=\"title[$book[id]]\" value=\"$book[title]\">" when this is sent w/ the form, the receiving page doesn't treat the variable "title," which is sent as something like -title%5B17%5D=The+Fountainhead- as an array. Does anyone have any idea why? Thanks Daniel http://www.php.net/manual/ref.array.php
