imap_getmailboxes

(PHP 4, PHP 5)

imap_getmailboxesLeer la lista de buzones, devolviendo información detallada de cada uno

Descripción

array imap_getmailboxes ( resource $imap_stream , string $ref , string $pattern )

Obtiene información sobre los buzones.

Parámetros

imap_stream

IMAP stream devuelto por imap_open().

ref

ref normalmente debería ser la especificación del servidor como está descrita en imap_open()

pattern

Especifica donde en la jerarquía del buzón para empezar a buscar.

Hay dos caracteres especiales que se pueden pasar como parte del pattern: '*' y '%'. '*' significa devolver todos los buzones. Si se pasa el pattern como '*', se obtendrá una lista de toda la jerarquía del buzón. '%' significa devolver sólo el nivel actual. '%' como el parámetro pattern devolverá solamente el nivel superior de los buzones; '~/mail/%' en UW_IMAPD devolverá cada buzón en el directorio ~/mail, pero no en los subdirectorios de ese directorio.

Valores devueltos

Devuelve un array de objetos que contienen la información de los buzones. Cada objeto tiene los atributos name (nombre), especificando el nombre completo del buzón; delimiter (delimitador), que es el delimitador de jerarquía de la parte de la jerarquía en la que está este buzón, y attributes (atributos). Attributes es una máscara de bits que puede comprobar con:

  • LATT_NOINFERIORS - Este buzón contiene, y no puede contener ningún "hijo" (no hay buzones por debajo de este). Una llamada a imap_createmailbox() no funcionará con este buzón.

  • LATT_NOSELECT - Es solo un contenedor, no un buzón - no se puede abrir.

  • LATT_MARKED - Este buzón está marcado. Esto significa que puede contener mensajes nuevos desde la última vez que se comprobó. No proporcionado por todos los servidores IMAP.

  • LATT_UNMARKED - Este buzó no está marcado, no contiene nuevos mensajes. Si se proporciona MARKED o UNMARKED, se puede asumir que el servidor IMAP soporta esta característica para este buzón.

Ejemplos

Ejemplo #1 Ejemplo de imap_getmailboxes()

<?php
$mbox 
imap_open("{imap.example.org}""username""password"OP_HALFOPEN)
      or die(
"no se puede conectar: " imap_last_error());

$lista imap_getmailboxes($mbox"{imap.example.org}""*");
if (
is_array($lista)) {
    foreach (
$lista as $clave => $valor) {
        echo 
"($clave) ";
        echo 
imap_utf7_decode($valor->name) . ",";
        echo 
"'" $valor->delimiter "',";
        echo 
$valor->attributes "<br />\n";
    }
} else {
    echo 
"imap_getmailboxes falló: " imap_last_error() . "\n";
}

imap_close($mbox);
?>

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.

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

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 (

$setAttribute['LATT_NOSELECT'] = true;

    if (

$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']));

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
}
?>
