Interesting that imap_headerinfo() does not allow a UID for the $msg_number field like all other fetching functions seem to allow.
If you want to use a UID to fetch the headers, use this two-step process:
<?php
/*
* assumes $mbox is your stream, and $uid is set
* properly. Proper error checking is up to you.
*/
$hText = imap_fetchbody($mbox, $uid, '0', FT_UID);
$headers = imap_rfc822_parse_headers($hText);
?>
The result is the same as the output of imap_headerinfo(), but you get to use the UID.

imap_fetchheader — Returns header for a message
Descrierea

( resource

message_num -
The message number

The possible
flagsare:-
FT_UID- Themsgnoargument is a UID -
FT_INTERNAL- The return string is in "internal" format, without any attempt to canonicalize to CRLF newlines -
FT_PREFETCHTEXT- The RFC822.TEXT should be pre-fetched at the same time. This avoids an extra RTT on an IMAP connection if a full message text is desired (e.g. in a "save to local file" operation)
-

This function ignore that some header value have multiple lines...
<?php
// connecting to imap mailserver
$connection = @imap_open("{localhost:143/imap}INBOX", "your_username", "your_password");
// get imap_fetch header and put single lines into array
$header = explode("\n", imap_fetchheader($connection, 1));
// browse array for additional headers
if (is_array($header) && count($header)) {
$head = array();
foreach($header as $line) {
// is line with additional header?
if (eregi("^X-", $line)) {
// separate name and value
eregi("^([^:]*): (.*)", $line, $arg);
$head[$arg[1]] = $arg[2];
}
}
}
// now are all contained additional headers in array $head
?>
I write this simple function....
$mbox = imap_open("{localhost:143/imap}INBOX", "your_username", "your_password");
$mid=1 // Message id
// Get headers
$header = imap_fetchheader($mbox, $mid);
// Split on \n
$h_array=split("\n",$header);
foreach ( $h_array as $h ) {
// Check if row start with a char
if ( preg_match("/^[A-Z]/i", $h )) {
$tmp = split(":",$h);
$header_name = $tmp[0];
$header_value = $tmp[1];
$headers[$header_name] = $header_value;
} else {
// Append row to previous field
$headers[$header_name] = $header_value . $h;
}
}

<?PHP
$headers=imap_fetchheader($imap, $msgid);
preg_match_all('/([^: ]+): (.+?(?:\r\n\s(?:.+?))*)\r\n/m', $headers, $matches);
?>
Works quite well for splitting headers,
$matches will contain 3 arrays:
$matches[0] are the full-lines (To: Jille@devnull.quis.cx\r\n)
$matches[1] will be the header (To)
$matches[2] will be the value (Jille@devnull.quis.cx)
In multi-line values the 'multilining is not stripped!'
this could be achieved with something like:
<?PHP
preg_replace('/\r\n\s+/m', '', $matches[2]);
?>

I spend lot of time find out how I can detect messages with
different priorities. When I read users notes I remember
function imap_fetchheader which show header of message
and additional headers too. Because I'm so lazy to work with
regular expressions I required my frend for writing code
- thanx Znouza.
And there is... :)
<?php
// connecting to imap mailserver
$connection = @imap_open("{localhost:143/imap}INBOX", "your_username", "your_password");
// get imap_fetch header and put single lines into array
$header = explode("\n", imap_fetchheader($connection, 1));
// browse array for additional headers
if (is_array($header) && count($header)) {
$head = array();
foreach($header as $line) {
// is line with additional header?
if (eregi("^X-", $line)) {
// separate name and value
eregi("^([^:]*): (.*)", $line, $arg);
$head[$arg[1]] = $arg[2];
}
}
}
// now are all contained additional headers in array $head
?>

Here is a simple function to get an array with all headers.
<?php
function mail_header_parse($mbox,$msg){
$header=imap_fetchheader($mbox,$msg);
preg_match_all("/^([^\r\n:]+)\s*[:]\s*([^\r\n:]+(?:[\r]?[\n][ \t][^\r\n]+)*)/m",$header,$matches,PREG_SET_ORDER);
foreach($matches as $match){
$match[2]=iconv_mime_decode($match[2],ICONV_MIME_DECODE_CONTINUE_ON_ERROR,'utf-8');
if(is_array($headers[$match[1]])){
$headers[$match[1]][]=$match[2];
}elseif(isset($headers[$match[1]])){
$headers[$match[1]]=array($headers[$match[1]],$match[2]);
}else{
$headers[$match[1]]=$match[2];
}
}
return $headers;
}
?>

If you call the function with the bitmask-parameter FT_PREFETCHTEXT the /Seen flag of the message will be set.
