Please keep in mind that the "parameters" array is a stdClass object when there are no parameters, and NOT a zero-size array.
In PHP5 you'll get this error when iterating structure->parts[x]->parameters if there aren't any parameters for this part:
PHP Fatal error: Cannot use object of type stdClass as array in file.php on line 100
imap_fetchstructure
Description
object imap_fetchstructure ( resource imap_stream, int msg_number [, int options] )This function fetches all the structured information for a given message. The optional options parameter only has a single option, FT_UID, which tells the function to treat the msg_number argument as a UID. The returned object includes the envelope, internal date, size, flags and body structure along with a similar object for each mime attachment. The structure of the returned objects is as follows:
表格 1. Returned Objects for imap_fetchstructure()
| type | Primary body type |
| encoding | Body transfer encoding |
| ifsubtype | TRUE if there is a subtype string |
| subtype | MIME subtype |
| ifdescription | TRUE if there is a description string |
| description | Content description string |
| ifid | TRUE if there is an identification string |
| id | Identification string |
| lines | Number of lines |
| bytes | Number of bytes |
| ifdisposition | TRUE if there is a disposition string |
| disposition | Disposition string |
| ifdparameters | TRUE if the dparameters array exists |
| dparameters | An array of objects where each object has an "attribute" and a "value" property corresponding to the parameters on the Content-disposition MIMEheader. |
| ifparameters | TRUE if the parameters array exists |
| parameters | An array of objects where each object has an "attribute" and a "value" property. |
| parts | An array of objects identical in structure to the top-level object, each of which corresponds to a MIME body part. |

A class for searching through a stucture object.
You can search matching 1-3 parameters or use the methods included.
Feel free to use it, correct it or extend it if you please. Enjoy!
http://lintoo.dk/public/structureengine.class.phps
The code was too wide for this manual, so I hope the link above will do. Here a quick overview instead:
<?php
class StructureEngine {
private $structureObject;
public function __construct($structureInfo) {}
public function locatePlain() {}
public function locateHTML() {}
public function locateAttachments() {}
private function checkParam($part, $type, $value) {}
private function findParts($partsArray, $prefix, $param1Type = 'type', $param1Value = 0, $param2Type = null, ...) {}

I think the following line (when building attachment information)
>>> "filename" => $parts[$i]->parameters[0]->value
needs to be
>>> "filename" => $parts[$i]->dparameters[0]->value
The first version generated a PHP warning under PHP 5.0.3. The second version actually gets the filename.

I've created a function which simply extracts basic message content as a string ($content) and attachments as an array ($attachments). I've tested it with messages from Outlook, Outlook Express and Hotmail. Perhaps it's useful to anyone.
<?php
$struct = imap_fetchstructure($mbox, $mid);
$parts = $struct->parts;
$i = 0;
if (!$parts) { /* Simple message, only 1 piece */
$attachment = array(); /* No attachments */
$content = imap_body($mbox, $mid);
} else { /* Complicated message, multiple parts */
$endwhile = false;
$stack = array(); /* Stack while parsing message */
$content = ""; /* Content of message */
$attachment = array(); /* Attachments */
while (!$endwhile) {
if (!$parts[$i]) {
if (count($stack) > 0) {
$parts = $stack[count($stack)-1]["p"];
$i = $stack[count($stack)-1]["i"] + 1;
array_pop($stack);
} else {
$endwhile = true;
}
}
if (!$endwhile) {
/* Create message part first (example '1.2.3') */
$partstring = "";
foreach ($stack as $s) {
$partstring .= ($s["i"]+1) . ".";
}
$partstring .= ($i+1);
if (strtoupper($parts[$i]->disposition) == "ATTACHMENT") { /* Attachment */
$attachment[] = array("filename" => $parts[$i]->parameters[0]->value,
"filedata" => imap_fetchbody($mbox, $mid, $partstring));
} elseif (strtoupper($parts[$i]->subtype) == "PLAIN") { /* Message */
$content .= imap_fetchbody($mbox, $mid, $partstring);
}
}
if ($parts[$i]->parts) {
$stack[] = array("p" => $parts, "i" => $i);
$parts = $parts[$i]->parts;
$i = 0;
} else {
$i++;
}
} /* while */
} /* complicated message */
echo "Analyzed message $mid, result: <br />";
echo "Content: $content<br /><br />";

Hey people, get the message attachments with this code:
<?php
$mbox = imap_open("$imap_server".$f,$name,$pass);
// delibertely choose a message with an attachment
$info = imap_fetchstructure($mbox, $mno);
// find out how may parts the object has
$numparts = count($info->parts);
$i=0;
// find if multipart message
if ($numparts >1)
{
echo "<b>More than one part</b><br><br>";
foreach ($info->parts as $part)
{
if ($part->disposition == "INLINE")
printf("Inline message has %s lines<BR>", $part->lines);
elseif ($part->disposition == "attachment")
{
$i++;
echo $i." Attachment/s found!<br>";
echo "Filename: ".$part->dparameters[0]->value."<br><br>";
}
}
}
else
echo "Only one part";
imap_close($mbox);

About above comment and source code I wrote: certainly, plain/html text files are attachments, but I've written my code thinking about web IMAP clients, where text parts are not for downloading, simply they are shown. That's the reason.
Thanks anyway. :)

I have written a code that check's for attachments.
There is a slight problem with the above code;
when you send a mail with a .txt document as attachment
the type will be 0 and so there won't be a attachment found.
I check for the disposition of the body part witch can be inline or attachment.
If this is an attachment he will display it.
You an also mix up both codes by checking on the type and the disposition.
//////////////////////////////////
/// $mbox = connection
/// $a_mails_sort[$i] = message id
$structuur = imap_fetchstructure($mbox,$a_mails_sort[$i]);
$bericht_delen=$structuur->parts;
for($i_delen = 0; $i_delen<=count($bericht_delen);$i_delen++)
{
if($bericht_delen[$i_delen]->disposition == "attachment")
{
$attachment = "OK";
}// end if

}
else
{
echo("You don't have attachment(s)");
}
function checkAttachments($estMsg)
{
if(($estMsg->type!=0) && ($estMsg->type!=1))
{
// Text and multipart parts will not be shown as attachments
return(true);
}
else
{
// If there's no attachments, parts inside will be checked
if($estMsg->parts)
{
$partMsg=$estMsg->parts;
$i=0;
// Parts will be checked while no attachments found or not all of them checked
while(!(checkAttachments($partMsg[$i])) && ($i<sizeof($estMsg->parts)))
{

else
{
return(true);

After many long hours of pouring over the object returned by imap_fetchstructure() I came up with the solution posted at the following url:
http://p2p.wrox.com/topic.asp?TOPIC_ID=9063
The url above provides an example of how to access variables in the object returned by imap_fetchstructure(). This class creates an object with member variables containing the correct part numbers which are compatible with the imap_fetchbody() function.
The structure returned looks something like this:
0 Raw Headers
$this->pid[$mid][0] = 1 text/plain top level message
$this->pid[$mid][1] = 2 message/rfc822 entire unparsed message
multipart/mixed - part is skipped!
2.0 Raw Headers
$this->pid[$mid][2] = 2.1 multipart/alternative contains unparsed contents of next subpart (text/plain && text/html)
2.1.0 Raw Headers
$this->pid[$mid][3] = 2.1.1 text/plain 2nd level inline embedded message
$this->pid[$mid][4] = 2.1.2 text/html
$this->pid[$mid][5] = 2.2 message/rfc822 entire unparsed message
multipart/mixed - part is skipped!
2.2.0 Raw Headers
$this->pid[$mid][6] = 2.2.1 multipart/alternative
$this->pid[$mid][7] = 2.2.1.1 text/plain 3rd level inline embedded message
$this->pid[$mid][8] = 2.2.1.2 text/html
$this->pid[$mid][9] = 2.2.2 image/jpeg
$this->pid[$mid][10] = 2.2.3 image/jpeg
$this->pid[$mid][11] = 2.2.4 image/jpeg
$this->pid[$mid][12] = 2.2.5 image/gif
Its important to note why multipart/related, multipart/mixed and certain multipart/alternative (if parent part is message/rfc822 && not multipart/mixed) parts are skipped, imap_fetchbody **does not** retreive a message part for these parts. Which isn't a bug, as I have read in other places, these parts exist for the purpose of designing the viewer portion of a mail application. Also, headers aren't assigned part numbers here because they are easy to pick out.

For people just beging this may help alot as I spent a couple hours just trying to relize how exact the array was stored. (at the time I did not know the print_r function :P)
$struct = imap_fetchstructure($mbox, $msgnumber);
print_r($struct);
Will give you a better example for your messages but they are called as $struct using the varible method above.
$struct->type; //would return the type
$struct->encoding //would return the encoding
and etc..
This can be done many different ways but that is the basics on pulling the info out of the structure of fetchstructure itself, I hope it helps someone starting because it wouldve helped me :/.

If you are getting CHARSET as US-ASCII even if the header has a Content-Type: field, make sure the header also has a MIME-Version: field.
For example, the following header will correcty report charset as KOI8-R
MIME-Version: 1.0
Content-Type: text/plain; charset="koi8-r"
Without the MIME-Version it will be reported as US-ASII

$struct->parts[$i-1] = imap_bodystruct( $conn, $curMsg, $i );
$j = 1;
while( imap_fetchbody( $conn, $curMsg, "$i.$j" ) ){
$struct->parts[$i-1]->parts[$j-1] = imap_bodystruct( $conn, $curMsg, "$i.$j" );

If your imap_fetchstructure not retrive all parts, write it:
$struct = imap_fetchstructure( $conn, $curMsg );
$i = 1;
while( imap_fetchbody( $conn, $curMsg, $i ) ){
$struct->parts[$i-1] = imap_bodystruct( $conn, $curMsg, $i );
$i++;

I'm using freeBSD and had lots of problems with all functions/mail applications i could find on the net...
So i'm writing my own now..
Most of the stuff works fine now.. but i'm still working on the chooser to select the best part to show. (plain or HTML).
The #1 problem is that most functions give the wrong ID numbers beck to fetch the body.
Here's a sollution to that problem.. :P
// Debug function.. always handy until it's 100% completed..
$attachments = array(); $dispos=0;
$debug=true;
function doDebug($msg){
global $debug, $debug_depth, $dispos;
if($debug){
for($y = 0; $y < $debug_depth; $y++) echo(" ");
if($dispos == 0) echo($msg."<br/>"); else echo("<i>".$msg."</i><br/>");
}
}
function Check_Part($part,$id){
global $attachments, $debug, $debug_depth, $dispos; $ans=sizeof($attachments);
doDebug("+Checking part $id");
$debug_depth++;
doDebug("Parttype=".$part->type ."/". mimetype($part->type) ."/". $part->subtype);
if($part->ifdisposition){ $dispos++; doDebug("<b>Disposition</b>"); }
if($part->ifdescription){ doDebug("<b>Description=".$part->description."</b>"); }
switch($part->type){
case 1: if((strtolower($part->subtype) == "mixed")
or (strtolower($part->subtype) == "alternative")
or (strtolower($part->subtype) == "related")) break;
default: $an = sizeof($attachments);
if($part->ifdparameters){
$dpara = $part->dparameters;
for ($v=0;$v<sizeof($dpara);$v++){
if (eregi("filename", $dpara[$v]->attribute))
$fname = $dpara[$v]->value;}
}
if($part->ifparameters){
if(empty($fname)){
$para = $part->parameters;
for ($v=0;$v<sizeof($para);$v++){
if (eregi("name", $para[$v]->attribute)) $fname = $para[$v]->value;
}
}
}
if(empty($fname))$fname = "Onbekend";
$attachments[$an]->id = ($an+1);
$attachments[$an]->part = $id;
$attachments[$an]->filename = $fname;
$attachments[$an]->type=$part->type;
$attachments[$an]->subtype=$part->subtype;
$attachments[$an]->dispos=$dispos;
$attachments[$an]->size=$part->bytes;
doDebug("Filename=".$attachments[$an]->filename); break;
}
for($x = 0; $x < count($part->parts); $x++){
Check_Part($part->parts[$x], $id.".".($x+1));
}
doDebug("Dit deel had iets nuttigs.");
if($part->ifdisposition) $dispos--;
$debug_depth--;
doDebug("-End of part $id");
}
function decode_mail($mbox, $msg){
global $attachments, $debug, $debug_depth;
doDebug("+Decoding message $msg"); $debug_depth++;
$obj = imap_fetchstructure($mbox, $msg, FT_UID); $moet_werken=true; $id=1;
while($moet_werken){
Check_Part($obj, $id);
$moet_werken=false;
}
$debug_depth--; doDebug("-End of message $msg");
}
Now to get this to work..
Decode_Mail([Mailbox connection], [Message Number]);
this is the outpu attachment array..
1--1.1.1--Onbekend--0--PLAIN--0--31
2--1.1.2--Onbekend--0--HTML--0--29
3--1.2--Beschrijving Nieuw E.doc--3--MSWORD--1--613718
--------------------------------------
PS.. "Onbekend" is dutch for "Unknown".
Good luck.

you can easily see through everything with these functions:
function printarray($array){
while(list($key,$value) = each($array)){
if(is_array($value)){
echo $key."(array):<blockquote>";
printarray($value);//recursief!!
echo "</blockquote>";
}elseif(is_object($value)){
echo $key."(object):<blockquote>";
printobject($value);
echo "</blockquote>";
}else{
echo $key."==>".$value."<br />";
}
}
}
function printobject($obj){
$array = get_object_vars($obj);
printarray($array);
}
end then do this:
$struct = imap_fetchstructure($box,$mailnr);
//$struct is een object!!
drukobjectaf($struct);
you get an extended tree-view into the hierarchie of objects and arrays
Comparing different mails(changing thenumber) may bring more clarity into this matter
(these functions may not work properly as they are translated from my dutch original, but they ought to be OK)

I think the above note about attachments is wrong. I tested sending files with and without attachments and I get the following<br>
with attachment: type=3 bytes=343648
no attachment: type=0 bytes=2
so checking for $struct->bytes == " " means nothing. At least in my test
running windows 2000, php4.2.1 using outlook and exchange. It seems that cheking the type will be more reliable

This function sets MIME charset
parameter value to US-ASCII when
either Content-Type header is missing
or Content-Type header doesn't have
charset parameter. This may be compliant
to RFC 822, but this poses
a problem for a calling function that
has to deal with untagged messages
in MIME charset other than US-ASCII.
To work around this, US-ASCII
has to be treated as the absence of MIME charset.

There's a little mistake in the code above!
The second echo must return "The message has no attachment!".
And that code must have some some additional thing to work properly! Maybe I must use ->parts to determine how many parts has a particular message!

There's a simple way to check weither a particular mail message has an attachment or not. I'm not sure that it is 100% true but here it is a sample code:
<?
$msg_structure = imap_fetchstructure($mail_inbox, $msg_id);
if($msg_structure->bytes == "")
{
echo "The message has attachment!";
}
else
{
echo "The message has attachment!";
}
?>
Please, test this code and let me know is it working properly or not! Thanks in advance!

Somebody must include some good examples of how to decode a message with and without an attachement.
I'm writing a web based email, and it wasn't verry easy for me to understand that part.
After a week of searching I still don't get it very well, but now (I think and hope) I'm able to write it...
Yet I'm not that good with it, so I'm not able to put an example in it myself...

It's better to use special constants instead of digits for primary content-type:
TYPETEXT unformatted text
TYPEMULTIPART multiple part
TYPEMESSAGE encapsulated message
TYPEAPPLICATION application data
TYPEAUDIO audio
TYPEIMAGE static image (GIF, JPEG, etc.)
TYPEVIDEO video
TYPEOTHER unknown
These constants are documented in the source code of IMAP extension but they are still undocumented here :(

Point of clarification:
The seventh primary body type is not "Other" as documented, but actually "Model". This encompasses IGES, VRML, MESH, DWF, etc.
http://www.isi.edu/in-notes/iana/assignments/media-types/media-types
"Other" is the eigth primary body type.

Assuming $struct = imap_fetchstructure($x,$y);
It is important to note that if a message has NO attachements, $struct->parts is an empty array, and $struct->bytes has a value. If a message as ANY attachements, $struct->bytes ALWAYS = 0. To get the size of the primary body, you have to call structure->part[0]->bytes. To get the size of the whole message, either strlen(imap_body) or add up the ->bytes of all the parts.
Another interesting note:
When there is body text and no attachements:
count($struct->parts) = 0
When there is body text and 1 attachement:
count($struct->parts) = 2
These imap functions could really use better documentation. Like giving the meathods for the dparameter and parameter classes...

Parsing the recursive object returned from imap_fetchstructure is easy. However trying to figure out the name of the section to pass to imap_fetchbody() isn't quite so straight forward because the naming conventions for the MIME sections are odd. If you copy and paste the following function you can pass an UID of an IMAP message and it will print out a hierarchy of the message and label each section.
The only required parameters are $mbox and $em_uid. The other parameters are used when the function needs to call itself.
Two functions mime_encoding() and mime_type() are not included. All they do is return string for the integer represention of a mime type/encoding.
function imap_dbody($mbox, $em_uid, $mimeobj, $depth = 0, $section = 0)
{
// If this is the first run of the function then grab a object of the MIME structure of the message
if($section == 0) $mimeobj = imap_fetchstructure($mbox, $em_uid, FT_UID);
for($y = 0; $y < $depth; $y++) echo(" ");
echo(mime_type($mimeobj->type) . "/{$mimeobj->subtype}, ");
echo(mime_encoding($mimeobj->encoding) . " (<B>$section</B>)<BR>");
for($x = 0; $x < count($mimeobj->parts); $x++)
{
// If we are in the root of the object increment by whole integers
if($section == 0) $nsection = $x + 1;
// If we are in the object and the first sub-object of our object isn't multipart
// then increment the postfix by ".1" otherwise we are multipart or a message
// and leave the section id alone to be handled by the next code block
else if(($pos = strrpos($section, ".")) && $mimeobj->parts[0]->type != TYPEMULTIPART)
$nsection = substr($section, 0, $pos) . "." . ($x + 1);
else
$nsection = $section;
// If there are more parts to the part about to be processed reference it as a header with ".0"
// but only if the child of this child isn't MULTIPART
if(count($mimeobj->parts[$x]->parts))
{
// Funny really, if a mime section is a inline message that has a multipart body you reference the message
// mime section with "2" the inline message header with "2.0" and the subsections with "2.x"
// However if the mime section is a inline message with only 1 part then you reference the
// mime section in the message with 2.0 and the inline message body with 2.1
if(!($mimeobj->parts[$x]->type == TYPEMESSAGE && $mimeobj->parts[$x]->parts[0]->type == TYPEMULTIPART))
$nsection .= ".0";
else
$nsection .= "";
}
imap_dbody($mbox, $em_uid, $mimeobj->parts[$x], $depth + 1, $nsection);
}
// If after processing the entire MIME object the $x variable is still zero then we didn't
// process a multipart mime message, it's just normal email so say so here.
if($x == 0 && $section == 0)
{
echo(mime_type($mimeobj->type) . "/{$mimeobj->subtype}, ");
echo(mime_encoding($mimeobj->encoding) . " (<B>1</B>) (<B>NOT MIME MULTIPART</B>)<BR>");
}
}

It looks like some clients (e.g. outlook) can attach a file that has two mime-types associated with it, like:
<PRE>Content-Type: model/vrml,x-world/x-vrml
</PRE>
This bombs the parsing procedure somewhere in c-client, I guess, and as a result ifparameters is set to false for the respective part, and you can not retrieve filename, mimetype, or any other parameters.

haven't read any rfc's on it, but Pine is showing a message with an attachment with type = 9 to be type BINARY...

The documentation appears to be incorrect in stating that objects in the parts array cannot have another parts array in them. I have found the parts can be recursive.

the parts objects are identical in
structure to those returned by imap_fetchstructure, describing one subfolder each
parameters and dparameters are MIME-specific, theese contain the
extra parameters provided in the Content-Type and Content-Disposion Header lines such as Charset or Filename
