[RESOLVED] What does "2" stand for in $overview = imap_fetch_overview($mbox, "2,4:6", 0);

[mrcaveman]

In the php manuall this is the example used on imap_fetch_overview().

$overview = imap_fetch_overview($mbox, "2,4:6", 0);

I know what $mbox is the stream and the string should show message 4 to 6 (4:6). But if I change the 2 to 1, 3, 4 or 5 I get the exact same result (or do I?).

Does anyone know what the "2," stands for in this function?
(and what is the ", 0" (int options) good for?)

The manual didn't give any good explenation.

"2, 4:6" is the same as requesting message ids "2, 4, 5, 6"
in the same way that "3:5, 7, 9:11" is the same as requesting "3, 4, 5, 7, 9, 10, 11"

I have no idea about the options (possibly a flag of some sort?).
