[PHP] Re: POST-ing or GET-ing an array
Hi, I disagree that serialize/unserialize is the way to go, unless you're absolutely completely sure that there will only be a relatively small number of things in the array. As somebody mentioned briefly, the get request is limited to a certain number of bytes, and the string representing your serialized array could easily get too large to send on a get request. imho the best option is to use the session, which somebody already mentioned but didn't really elaborate... $_SESSION['my_array'] = $my_array; and on next_page (or any other page), you'd just use $_SESSION['my_array'] where you need. Another option would be to send the request as a post, and serialize the array into a hidden variable in your form; that way you won't have to worry (as much) about size constraints. (a post request is also limited in size, but it's so large that you probably would never approach the limit.) /nick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

But just to mention it at this point: if you have script-output (echo, print, print_r etc.) before any operation on $_SESSION, you should call start_session() at the start of the script. (I don't know if recent versions of PHP still _need_ this) and on next_page (or any other page), you'd just use $_SESSION['my_array'] where you need. I would suggest, unsetting the array in the next_page (or whatever) after you don't need it anymore: unset($_SESSION['my_array']); Another option would be to send the request as a post, and serialize the array into a hidden variable in your form; that way you won't have to worry (as much) about size constraints.

RE: [PHP] Re: POST-ing or GET-ing an array
You need to call start_session before accessing $_SESSION variables UNLESS you have PHP configured to automatically start_session (which is off by default). You need to start_sesion so that scripts that don't need $_SESSION don't go through the overhead of starting session.
