I got a note that:
if u want to set a mail to "//Unseen", which not exists,
do it like this:
imap_clearflag_full($your_imap_connection,
$number_of_message,"//Seen");
but, remember to do
imap_close($imap, CL_EXPUNGE);
@ the END! so that it will be confirmed!
Cheers,

Remember to specify your flags like '\\Seen' rather than "\\Seen".
Of course, flags are an IMAP feature, not a POP feature.
Resetting \\Seen works from PHP 4.3 works fine on the modern mail servers I've tested.
imap_clearflag_full() and imap_setflag_full() seem to only change messageflags permanently with IMAP connections, not with POP3 connections.
This function seems not to save the \\Seen flag permanently.
