Your second example is correct, and is also a heck of a lot more efficient.
The first example doesn't work because every time you call imap_expunge(), the pop3
server actually deletes the messages, and the message numbers change. So if you have
messages 1, 2, 3, 4, you delete 1, and you call imap_expunge, you don't have 2, 3, 4,
you have 1, 2, 3. Your code then tries to delete number 2, leaving you with 1, 2 ...
you see where this is going.

As I wrote the following code I found the strong situation in imap_expunge(). It will
expunge mails with odd number only but not every mail as I expected.
$mbox = imap_open("{localhost/pop3:110INBOX", "test", "test");
$num_msg = imap_num_msg($mbox);
echo "start at $num_msg...<br>";
for ( $i=1; $i<=$num_msg; $i++ ) {
imap_delete($mbox, $i);
imap_expunge($mbox);
echo "doing $i....<br>";
}
imap_expunge($mbox);
$num_msg = imap_num_msg($mbox);
echo "now is $num_msg<br>";
imap_close($mbox);
I have the following output:
start at 10...
doing 1....
doing 2....
doing 3....
doing 4....
doing 5....
doing 6....
doing 7....
doing 8....
doing 9....
doing 10....
now is 5
If I modify the code as following the problem solved:
for ( $i=1; $i<=$num_msg; $i++ ) {
imap_delete($mbox, $i);
echo "doing $i....<br>";
}
imap_expunge($mbox);
The result is coreect and all mail has been deleted.
This bug occurs if a web mail system with a pop server try to delete lots of spam at a
time.
