Description:
------------
Hi,

The imap_search function is not compliant with the RFC 3501.
We can not search messages using their UID.

Example : imap_search("UID 200:*, $link);

The output goes in the error_log with this message :

[27-Oct-2010 12:34:35] PHP Notice:  Unknown: Unknown search criterion: UID (errflg=2) in Unknown on line 0

Imo, this functionnality should be implemented for building advanced webmails.

This is not a real *bug*, but more a lack of functionnality.

There's a typo in the imap_search(), the resource is, of course, before the search string :)

The search string I provided in the example is to fetch all messages where UID>=200.

The goal of this search is to keep up to date a webmail, without retriving the whole mailbox content each time you want to synchronize it, since you can't rely on the SEEN/RECENT flag (if the mailbox is opened with another software in the meantime). Using dates to achieve that is a dirty workaround...

imap_search() is stuck with the RFC 1176 (august 1990 !!111!!!)

PS: Sorry for the triple-post, this is my first bug report and I didn't know we can't edit things.

PHP's IMAP extension simply calls c-client, so it's entirely dependent on what that library supports in terms of search syntax. There's nothing we can really do on the PHP side to help.

The IMAP c-client certainly supports UID ranges.  This is a PHP issue.

   SEARCHSET *msgno;	a set of message sequence numbers
   SEARCHSET *uid;	a set of unique identifiers

PHP calls c-client with two functions, we don't have any control over the syntax.

pgm = mail_criteria(search_criteria);

mail_search_full(imap_le_struct->imap_stream, (argc == 4 ? charset : NIL), pgm, 
flags);
