imap_fetch_overview — Liefert einen Auszug aus den Kopfdaten von Nachrichten
Die Funktion fragt die Kopfdaten der mit sequence() angegebenen Nachrichten ab und liefert einen Auszug daraus zurück.
Eine von imap_open() zurückgegebene IMAP-Verbindung.
Beschreibung der gewünschten Nachrichten. Mehrere Nachrichten können durch Komma getrennt angegeben werden (X,Y), Nachrichtenbereiche durch einen Doppelpunkt zwischen erster und letzter Nachricht (X:Y).
Wenn dieser Parameter auf FT_UID gesetzt wird werden die einzelnen Einträge der Nachrichtenliste sequence als UIDs und nicht als Nachrichtennummern interpretiert.
Gibt ein Array von Objekten, die jeweils einen Nachrichtenkopf beschreiben, zurück. Das Objekt hat eine Eigenschaft nur dann, wenn sie auch existiert. Die möglichen Eigenschaften sind:
Beispiel #1 imap_fetch_overview()-Beispiel
<?php
$mbox = imap_open("{imap.example.org:143}INBOX", "username", "password")
or die("can't connect: " . imap_last_error());
$MC = imap_check($mbox);
// Hole eine Übersicht aller Nachrichten in der 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);
?>
This seems to retrieve incomplete values for headers, instead of getting the entire value, it gets the first. for example, this is a valid To: header
To: foo1@example.com,foo2@example.com
foo3@example.com
but imap_fetch_overview will only return:
foo1@example.com
Just a quick note, in case anyone else has this trouble.
Remeber that imap_fetch_overview returns an array! So even if you call it for only one message, you'll still need to pick out the first element.
<?php
// fetch overview:
$overview = imap_fetch_overview($handle, $uid, FT_UID);
// echo out, e.g., from field:
echo htmlspecialchars($overview[0]->from);
// ^^^ note the index!
?>
It may seem like a stupid error, but I spent a good half hour wondering why it wasn't working until I var_dump'ed $overview.
That's right:
calling imap_fetch_overview() once is faster, than calling it
in a loop.
But if you want to get a "day sorted" list, you need to call it in a loop, cause if you enter a "string" of UIDs, they are always sorted by UID, not by the order you entered it.
Heres a little example how to get a date-sorted list:
<?php
/*Sort all msgs by Arrival Date. Newest = 0, oldest = Array Count*/
/*returns an array, containing the UIDs of messages*/
$SortedArray = imap_sort($Handle,SORTARRIVAL,1,SE_UID);
For ($i = $Start; $i< $Start + $Limit; $i++){
/*Read UID from Sorted Array*/
$UID = $SortedArray[$i];
/*Get Detailed MSG Infos*/
$Overview = imap_fetch_overview($Handle, $UID, FT_UID);
[...]
}
?>
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;$i<count($tmp);$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.
<?php
/**

*
* @param int $page page number to get
* @param int $per_page number of results per page
* @param array $sort array('subject', 'asc') etc
*
* @return mixed array containing imap_fetch_overview, pages, and total rows if successful, false if an error occurred
* @author Raja K
*/
public function listMessages($page = 1, $per_page = 25, $sort = null) {
$limit = ($per_page * $page);
$start = ($limit - $per_page) + 1;
$start = ($start < 1) ? 1 : $start;
$limit = (($limit - $start) != ($per_page-1)) ? ($start + ($per_page-1)) : $limit;
$info = imap_check($this->_imap_stream);
$limit = ($info->Nmsgs < $limit) ? $info->Nmsgs : $limit;
if(true === is_array($sort)) {
$sorting = array(
'direction' => array( 'asc' => 0,
'desc' => 1),
'by' => array( 'date' => SORTDATE,
'arrival' => SORTARRIVAL,
'from' => SORTFROM,
'subject' => SORTSUBJECT,
'size' => SORTSIZE));
$by = (true === is_int($by = $sorting['by'][$sort[0]]))
? $by
: $sorting['by']['date'];
$direction = (true === is_int($direction = $sorting['direction'][$sort[1]]))
? $direction
: $sorting['direction']['desc'];
$sorted = imap_sort($this->_imap_stream, $by, $direction);
$msgs = array_chunk($sorted, $per_page);
$msgs = $msgs[$page-1];
}
else
$msgs = range($start, $limit); //just to keep it consistent
$result = imap_fetch_overview($this->_imap_stream, implode($msgs, ','), 0);
if(false === is_array($result)) return false;
//sorting!
if(true === is_array($sorted)) {
$tmp_result = array();
foreach($result as $r)
$tmp_result[$r->msgno] = $r;
$result = array();
foreach($msgs as $msgno) {
$result[] = $tmp_result[$msgno];
}
}
$return = array('res' => $result,
'start' => $start,
'limit' => $limit,
'sorting' => array('by' => $sort[0], 'direction' => $sort[1]),
'total' => imap_num_msg($this->_imap_stream));
$return['pages'] = ceil($return['total'] / $per_page);
return $return;
}
?>
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.
<?php
$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'<BR>";
imap_close($mbox);
?>
