imap_uid — Retourne l'UID d'un message
imap_uid() retourne l'UID pour le message
msgno. Un UID est un identifiant unique
que ne change jamais, alors que le numéro du message dans
la liste des messages peut changer à toute modification
de la boîte aux lettres.
C'est la fonction inverse de imap_msgno().
L'UID d'un message donné.
| Version | Description |
|---|---|
| 8.1.0 |
La paramètre imap attend désormais une instance de
IMAP\Connection ; auparavant, une ressource imap était attendue.

Note:
Cette fonctionnalité n'est pas supportée par les boîtes aux lettres POP3.
I would like to point out that, at least in the case of Gmail, the UIDs of emails are changed if they are moved from one folder to another. Even if moved back to the same folder the UIDs get incremented and thus changed.
I found this the hard way after relaying on the notion that UIDs do not change as I found almost everywhere in the docs.Please note that message_id in the header is NOT the UID - and its dangerous to use as many mail progs don't put a message id inBe aware that the uid is unique in a single mailbox. That means a message can have as much uids as mailboxesThe uid will change in case of unsing imap_expunge. Be shure that
all work ist done before using imap_expunge.
