Using IMAP to fetch emails in php

Question

I am using Imap function to fetch the emails through yahoo mail. Then i set the flag on each email because when in future i call the imap search i will not get the emails that are already fetched.This is how i get the emails.

$emails = imap_search($inbox,"UNFLAGGED");

Then i apply the flag using the code :

foreach($emails as $email_number) {
       imap_setflag_full($inbox, $email_number, "\\Flagged \\Seen", ST_UID);

But when i call the imap_search($inbox,"UNFLAGGED"); i get the same emails. The emails which are already been flagged should not fetch when i call the imap_search second time.

I Also tried imap_search($inbox,"unflagged") and imap_search($inbox,"Unflagged") and imap_search($inbox,"UnFlagged") but still all emails are fetched.

I tried imap_search($inbox,"UNSEEN") it is useful in case when the email is not read manually by user (Logging in yahoo mail and then read). In my case i need all the emails which are not "Flagged" by me using Imap.

Need help on this. Thanks in advance

You are searching message sequence numbers, but setting flags on UIDs. Pick one or the other. I suggest always using UIDs. Have you tried adding SE_UID to search:

$emails = imap_search($inbox, "UNFLAGGED", SE_UID);
