functions for sorting/paging functionality for imap mailboxes

[Yashesh Bhatia]

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.
