Bad message number error - php

Question

I am using a script to forward email addresses and getting bad message number error. the message number is parsed as an argument for the function and i am not sure how to get the message number and insert it as the argument. Please help. I am new to php. The error points out $structure = imap_fetchstructure($connection, $id, FT_UID); and $result['text'] = imap_body($connection, $id, FT_UID); parts. Please help me.
<?php

Answer 1

The FT_UID flag means that you are using message uid, rather than message sequence id. In order to get the uid for a given message, you have to use the msg_uid() function.
Since you are beginner, I hardly think this was your question, so here is complete example how to get the headers and the content of a given message:
<?php
$emailAddress = 'postmaster#example.com';
$password = 'someSecretPassword';
$server = 'localhost';
$folder = 'Inbox';
$dsn = sprintf('{%s}%s', $server, $folder);
$mbox = imap_open($dsn, $emailAddress, $password);
if (!$mbox) {
die ('Unable to connect');
}
$status = imap_status($mbox, $dsn, SA_ALL);
$msgs = imap_sort($mbox, SORTDATE, 1, SE_UID);
foreach ($msgs as $msguid) {
$msgno = imap_msgno($mbox, $msguid);
$headers = imap_headerinfo($mbox, $msgno);
$structure = imap_fetchstructure($mbox, $msguid, FT_UID);
var_dump($headers);
var_dump($structure);
}

I was getting the same error when inside the loop, after processing the email, I was moving the message to a different folder.
After I comment out the imap_move the error went away.
