說明
array imap_fetch_overview ( resource imap_stream, string sequence [, int options] )
This function fetches mail headers for the given sequence and returns an overview of their contents.
參數
imap_stream
An IMAP stream returned by imap_open().
sequence
A message sequence description. You can enumerate desired messages with the X,Y syntax, or retrieve all messages within an interval with the X:Y syntax
options
sequence will contain a sequence of message indices or UIDs, if this parameter is set to FT_UID.
返回值
Returns an array of objects describing one message header each. The object will only define a property if it exists. The possible properties are:

to - recipient
date - when was it sent
message_id - Message-ID
references - is a reference to this message id

size - size in bytes
uid - UID the message has in the mailbox
msgno - message sequence number in the mailbox
recent - this message is flagged as recent
flagged - this message is flagged

例 1. imap_fetch_overview() example
$mbox = imap_open("{imap.example.org:143}INBOX", "username", "password")
or die("can't connect: " . imap_last_error());
$MC = imap_check($mbox);
// Fetch an overview for all messages in INBOX
$result = imap_fetch_overview($mbox,"1:{$MC->Nmsgs}",0);
foreach ($result as $overview) {
echo "#{$overview->msgno} ({$overview->date}) - From: {$overview->from}
{$overview->subject}\n";
}
imap_close($mbox);

you want a sortet list of mails, but you get always the same order? your c-client seems to cause this. i realized this with linux libc6-2.3.6 and php-5.2.0
try this little code:
# here you try to sort by your criteria
$sort=@imap_sort($mbox,SORTDATE,1,SE_UID);
# here the order of the messages to fetch should be recognised, but it isn't
$tmp=@imap_fetch_overview($mbox,implode(',',$sort),FT_UID);
# so try to work around simply:
for($i=0;$i{ $liste[$i]=$tmp[array_search($tmp[$i]->uid,$sort)]; }
so now you can use the sort by date, address, and so on.

Here is a function to get messages from IMAP and sort them for pagination.

About the sequence sorting again.
I've found that there's a significant speed improvement by preparing the sequence and then fetch them at once with large mailboxes. On small mailboxes wyou will not notice a speed difference.
But then there's the sorting problem. I've spent all night fiuring out how to do this myself. I found the solution!
Prepare an array of messages with imap_sort. Create a second array that maps the message numbers to the actuall place in the fetched array.
You know it will be in numeric order so you can make an array map with the sort() function sorting it from high to low.
Then you can proces the array fetched with imap_fetch_overview with the array_map and you will have them sorted. If you need an example look in the Group-Office code classes/imap.class.inc in a version later then 2.04.

Not that this function and all other imap_fetch*-functions will download the whole message and not just the header information.

To further explain 'warrenfalk's comment, the following sequences are exactly the same, and always returns messages with lowest UID to highest UID:
1:5
5:1
1,2,3,4,5
5,4,3,2,1
3,2,5,1,4
(always returned as 1,2,3,4,5)

Note that these object-variables only exist when they are actually in the mail.
This means that if a mail has no subject, the property $val->subject will not exist.
Calling $val->subject will generate an notice:
Notice: Undefined property: subject in /home/html/inc/Mbox.php on line xxx
Use this to check it:
if (array_key_exists( "subject", get_object_vars($val)))
$subj=$val->subject;
else
$subj="";

This performance hint is useful if you need to print the result of imap_sort():
It's faster to prepare large string with UIDs and then to call imap_fetchoverview once than calling imap_fetchoverview in a loop.

I think if you go like a list, you can list your "hotmail" messages.
$mbox=imap_open("{imap.server.com}","user","pass");
$MC=imap_check($mbox);
$MN=$MC->Nmsgs;
$overview=imap_fetch_overview($mbox,"1:$MN",0);
$size=sizeof($overview);
for($i=$size-1;$i>=0;$i--){
$val=$overview[$i];
$msg=$val->msgno;
$from=$val->from;
$date=$val->date;
$subj=$val->subject;
echo "#$msg: From:'$from' Date:'$date' Subject:'$subj'
";
imap_close($mbox);
?>
