imap_fetchheader

(PHP 4, PHP 5)

imap_fetchheaderReturns header for a message

Description

string imap_fetchheader ( resource $imap_stream , int $msg_number [, int $options = 0 ] )

This function causes a fetch of the complete, unfiltered » RFC2822 format header of the specified message.

Parameters

imap_stream

An IMAP stream returned by imap_open().

msg_number

The message number

options

The possible options are:

  • FT_UID - The msgno argument 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)

Return Values

Returns the header of the specified message as a text string.

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
   
$header explode("\n"imap_fetchheader($connection1));

   
// 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
?>

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

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
   
$header explode("\n"imap_fetchheader($connection1));

   
// 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]);
?>

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.

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;
}
?>
