functions for sorting/paging functionality for imap mailboxes

hello, i'm implementing an imap based mail client and want to provide sorting / paging functionality for the inbox. there's a function to retrieve headers imap_headers (http://www.php.net/imap_headers) however, this gets headers for all messages in a mailbox(inbox). is there any function that will fetch headers similar to a SQL LIMIT clause (LIMIT offset, row_count) - so something like fetch 10 headers starting from 11. the sorting can be accomplished by the function imap_sort so i'm kindof stuck to get the paging functionality efficiently. (of course one can get all headers and then use the array index to simulate limit offset, row_count). thanks in advance. yashesh bhatia ---------------------------------------------------------------- Go Pre http://www2.localaccess.com/rlalonde/pre.htm ----------------------------------------------------------------
