Bypassing php.ini setting for file uploads?

Hi, I am trying to modify the php.ini settings for post_max_size and upload_max_filesize to allow for a custom script to upload files larger than 8MB, the default size limit set in php.ini. This is on a shared server, and my hosting company won't modify the limitation, although they will charge me $50/hr to code a custom script. Whatever! I'll just do it myself... but I don't know how. Also, http://docs.php.net/en/function.ini-set.html tells me that for post_max_size and upload_max_filesize: "Entry can be set in php.ini, ..htaccess or httpd.conf." Any help would be greatly appreciated!! Thanks, Matt Cassarino Cell: (206) 484-4626 Web: www.mattcass.com Email: mc@mattcass.com
