i am currently develop a simple IMAP client, when i call imap_getmailboxes() i receive a different values in attributes property of the mailbox object the problem is how can i manipulate these attributes to get a meaningful value,
if you make a hard search to find a solution for this, you will
not find any useful documents for this problem, let us take a closer look for this problem.
when i call imap_getmailboxes() against different IMAP servers i got these attribute values
[attributes] => 9
[attributes] => 1
[attributes] => 64
[attributes] => 32
[attributes] => 40
the documentation tell us that we check this attributes against four constants, these contents are
LATT_NOINFERIORS
LATT_NOSELECT
LATT_MARKED
LATT_UNMARKED
the value of these constants are
LATT_NOINFERIORS = 1
LATT_NOSELECT = 2
LATT_MARKED = 4
LATT_UNMARKED = 8
you can got this result by echo each constant, unfortunately the documentation not explain how we can check the attributes against the constants, after a long time of searching i find the answer in source code of c-client
(you can get the source from ftp://ftp.cac.washington.edu/imap/)
under \src\c-client you will find mail.h open it and you will find this
/* terminal node in hierarchy */
#define LATT_NOINFERIORS (long) 0x1
/* name can not be selected */
#define LATT_NOSELECT (long) 0x2
/* changed since last accessed */
#define LATT_MARKED (long) 0x4
/* accessed since last changed */
#define LATT_UNMARKED (long) 0x8
/* name has referral to remote mailbox */
#define LATT_REFERRAL (long) 0x10
/* has selectable inferiors */
#define LATT_HASCHILDREN (long) 0x20
/* has no selectable inferiors */
#define LATT_HASNOCHILDREN (long) 0x40
as you notice here these are our four constants and three additional constants
LATT_REFERRAL
LATT_HASCHILDREN
LATT_HASNOCHILDREN
then what is the value of these 3 attributes
LATT_REFERRAL 0x10 = 00010000 in binary, the bitmask value is 2^4 = 16 and so on, or simply echo this constant to get the value, then
LATT_REFERRAL = 16
LATT_HASCHILDREN = 32
LATT_HASNOCHILDREN = 64
finally the full list of constants will be
LATT_NOINFERIORS = 1
LATT_NOSELECT = 2
LATT_MARKED = 4
LATT_UNMARKED = 8
LATT_REFERRAL = 16
LATT_HASCHILDREN = 32
LATT_HASNOCHILDREN = 64
ok let's back to our attributes
[attributes] => 9
[attributes] => 1
[attributes] => 64
[attributes] => 32
[attributes] => 40
[attributes] => 9 this mean it's LATT_UNMARKED and LATT_NOINFERIORS 1+8 =9
[attributes] => 1 this mean LATT_NOINFERIORS
[attributes] => 64 this mean LATT_HASNOCHILDREN
[attributes] => 32 this mean LATT_HASCHILDREN
[attributes] => 40 this mean LATT_HASCHILDREN and LATT_UNMARKED 32+8=40
this just like linux file permission 7 mean read, write, and execute 4+2+1 read=4 write=2 execute=1
that is what i found, i hope this can help

imap_getmailboxes
(PHP 4, PHP 5, PHP 7, PHP 8)
imap_getmailboxes — Posta kutuları hakkında ayrıntılı bilgi döndürür
Açıklama
Posta kutusu listesini okuyup her PK için ayrıntılı bilgi döndürür.
Bağımsız Değişkenler
-
imap -
IMAP\Connection nesnesi.
-
hedef -
imap_open() işlevinde açıklandığı gibi normal olarak bir sunucu belirtimi olmalıdır.
Uyarıimap.enable_insecure_rsh iptal edilmedikçe bu bağımsız değişkene güvenilir olmayan verinin aktarılması güvenli değildir.
-
kalıp -
Posta kutusu hiyerarşisi içine aramanın başlayacağı yeri belirtir.
kalıpiçinde belirtilebilecek iki özel karakter vardır: Alt dizinlere inilmesini sağlayan '*' ve alt dizinlere inilmemesini sağlayan '%'.kalıpolarak '*' posta kutusu hiyerarşisi içindeki tüm posta kutularının listelenmesini, '%' ise sadece tepe seviyedeki posta kutularının listelenmesini sağlar.kalıpolarak '~/mail/%' belirtilirse alt dizinlere inilmeden sadece ~/mail dizini altındaki posta kutuları listelenir.
Dönen Değerler
Posta kutusu bilgilerini içeren nesnelerden oluşan bir dizi döner. Her
nesnenin üç özelliği vardır: Posta kutusunun ismini içeren
name, hiyerarşik ayracı içeren
delimiter ve attributes.
attributes özelliği şu değerleri içerebilen bir bit
maskesidir:
-
LATT_NOINFERIORS- "Çocuklar" olmaksızın posta kutusunun kendisi (bunun altında posta kutusu bulunmaz). Bir alt posta kutusu olmaz. Bu posta kutusu altında imap_createmailbox() çalışmaz. -
LATT_NOSELECT- Sadece bir taşıyıcıdır, bir posta kutusu değildir - bu açılamaz. -
LATT_MARKED- Posta kutusu imlidir. Yani, son erişimden bu yana yeni gelmiş iletiler var demektir. Her IMAP sunucusu bu bilgiyi sağlamaz. -
LATT_UNMARKED- Posta kutusu imsizdir, posta kutusunda yeni gelmiş ileti yoktur.MARKEDveyaUNMARKEDbilgisi sağlanmışsa IMAP sunucusunun bu posta kutusunda bu özelliği desteklediğini varsayabiliriz. -
LATT_REFERRAL- Bu taşıyıcının uzak bir posta kutusuna yönlendirmesi var. -
LATT_HASCHILDREN- Bu posta kutusunun seçilebilir alt öğeleri vardır. -
LATT_HASNOCHILDREN- Bu posta kutusunun seçilebilir alt öğeleri yoktur.
false döndürür.

The list of mailbox attributes in this document is very misleading. In particular the explanation of noinferiors is just wrong. It does not mean that the mailbox currently has no children, it means that it *cannot* have children ever. Also, it is untrue that marked and unmarked are only used by UW-IMAP. They are in the official IMAP specification and are used by at least Courier-imap as well.
One thing to watch out for, however, is broken IMAP servers which do send \Noinferiors when they mean that there are currently no children.
From the IMAP4rev1 specs (RFC 2060):
\Noinferiors
It is not possible for any child levels of hierarchy to exist
under this name; no child levels exist now and none can be
created in the future.
\Noselect
It is not possible to use this name as a selectable mailbox.
\Marked
The mailbox has been marked "interesting" by the server; the
mailbox probably contains messages that have been added since
the last time the mailbox was selected.
\Unmarked
The mailbox does not contain any additional messages since the
last time the mailbox was selected.

In case you print_r() or var_dump() the object and see an int for attribute, these are the constant integers for the bitmask.
1 LATT_NOINFERIORS
2 LATT_NOSELECT
4 LATT_MARKED
8 LATT_UNMARKED

i was looking for a function to test the attributes.
and it was hard to find an answer or code.
Maybe there is a function availeble, but i couldn't find it.
the first function: returns all mailboxes in on the server
The second function: returns a bitstring from the attr_number returned by getmailboxes()
The tirth function: returns an array with the active attributes on the specific mailbox
Last Line: is a combination of the functions: the output is, any map witch can hold no mail but only sub boxes...
<?php
function getFolders($mailbox, $serverString) {
$list = imap_getmailboxes($mailbox, $serverString, "*");
if (is_array($list)) {
foreach ($list as $key => $val) {
$mapname = str_replace($serverString, "", imap_utf7_decode($val->name));
if ($mapname[0] != ".") {
$list_folders[$key]['name'] = $mapname;
$list_folders[$key]['delimiter'] = $val->delimiter;
$list_folders[$key]['attributes'] = $val->attributes;
}
}
} else {
echo "imap_getmailboxes failed: " . imap_last_error() . "\n";
}
return $list_folders;
}
function IntToBin($number) {
$BitWaarde = 1;
$IntNum = $number;
$BinString = "";
if ($IntNum > 0) {
// bepaal de max bitwaarde aan de hand van $IntNum
while ($IntNum > $BitWaarde) {
$BitWaarde = $BitWaarde * 2;
}
// maken van een binaire string.
while ($BitWaarde >= 1 ) {
if ($IntNum < $BitWaarde) {
if ($BinString != "") $BinString .= "0";
} else {
$BinString .= "1";
$IntNum = $IntNum-$BitWaarde;
}
$BitWaarde = $BitWaarde / 2;
}
}
return $BinString;
}
function Attributes($BinString) {
$BinInt = (int)$BinString;
if ($BinInt >=1000){
$setAttribute['LATT_UNMARKED'] = true;
$BinInt = $BinInt-1000;
} else $setAttribute['LATT_UNMARKED'] = false;
if ($BinInt >=100){
$setAttribute['LATT_MARKED'] = true;
$BinInt = $BinInt-100;
} else $setAttribute['LATT_MARKED'] = false;
if ($BinInt >=10){
$setAttribute['LATT_NOSELECT'] = true;
$BinInt = $BinInt-10;
} else $setAttribute['LATT_NOSELECT'] = false;
if ($BinInt >=1){
$setAttribute['LATT_NOINFERIORS'] = true;
$BinInt = $BinInt-1;
} else $setAttribute['LATT_NOINFERIORS'] = false;
return $setAttribute;
}
foreach (getFolders($mailbox, $config['Server_string']) as $key => $val) {
$Attr = Attributes(IntToBin((int)$val['attributes']));
if (!$Attr['LATT_NOINFERIORS']) {
echo "<option value='".$val['name']."'>".$val['name']."</option>";
}
}

For the purposes of passing along the attributes as a json array, I wanted to pass the attributes as an indexed array to save on bandwidth and session storage. The human readable translation is then performed in javascript by relating each key to the proper attribute label. I also wanted a cleaner way of converting the attributes without calling another function or using a complex iteration. This puts each binary attribute into it's own array element for easy testing.
<?php
$mailboxes = imap_getmailboxes($mailbox, $username, $password);
foreach($mailboxes as $key=>$mailbox){
...
$attrs = preg_split('//',str_pad(decbin($mailbox->attributes),7,"0",STR_PAD_LEFT),8); // convert decimal to an array of attributes
array_shift($attrs); // Remove the extra element at the front of the array in position 0
...
}
?>
With temporary variables, the conversion would look like this.
<?php
$attr_binary = decbin($mailbox->attributes); // convert decimal to binary
$attr_binary = str_pad($attr_binary,7,"0",STR_PAD_LEFT); // pad with 0's on the left
$attrs = $preg_split('//',$attr_binary,8); // split into an array after each character
array_shift($attrs); // Remove the extra element at the front of the array in position 0
?>
By defining the attributes as a map to the array index, you can test as follows.
<?php
define("ATTR_NOINFERIORS",6);
define("ATTR_NOSELECT "5);
define("ATTR_MARKED ",4);
define("ATTR_UNMARKED ",3);
define("ATTR_REFERRAL ",2);
define("ATTR_HASCHILDREN ",1);
define("ATTR_HASNOCHILDREN ",0);
if ($attrs[ATTR_HASCHILDREN]){
// do something
}
?>
