IMAP to parse string?

[pmarg212]

Greetings,

I currently have incoming email piped to a php script using a .forward
file. I would like to be able to parse the incoming mail, perform
operations, and then fire back an email (immediately) to the sender.
Is there any way that I can use the php IMAP functions on either the
php://stdin stream (the means through which the email is piped as raw
text) or on a plain string?

If not, are there any recommendations for what I can use to parse an
incoming email which may or may not be MIME?

Thanks for any help you can provide,
Paul

I would rather recommend you to use procmail + formail
and call a php script if needed.

depends if you really need to to do that in php or not

IMAP?! IMAP is a mailbox access protocol which includes logging into a
mailbox, detecting folder structure, finding counts of unread messages,
retrieving particular messages and so on -- it's not for parsing e-mail
messages.

Exactly which parts of the message do you need to parse? Do you expect any
messages to have MIME types other than text/plain?

A quick and dirty example of parsing a text/plain message:

<?php

function get_raw_message ()
{
/* Your code to read message from stdin and
* return a string. For simplicity, convert
* "\r\n" to "\n" here too.
*/
}

function string2msg ($string)
{
/* Header and body are separated by first occurance of
* blank line. Split them apart.
*/
$bits = explode("\n\n", $string);
$headers_raw = array_shift($bi ts);
$body = implode("\n\n", $bits);
unset($bits);

/* Header lines may be folded. Unfold them. */
$headers = preg_replace('/\n\s+/', ' ', $headers_raw);

/* For each header line... */
$headers = explode("\n", $headers);
foreach ($headers as $h)
{
/* Split on first colon. */
$bits = explode(":", $h);
$key = strtolower(rtri m(array_shift($ bits)));
$val = ltrim(implode(" :", $bits));

/* Add it to $parsedhdrs array. Structure of
* array is like:
*
* $parsedhdrs = array(
* 'to' ='me@example.co m',
* 'from' ='you@example.o rg',
* 'received' =array(
* 'yourhost.examp le.com on Saturday',
* 'myhost.example .org on Friday night'
* ),
* 'content-type: text/plain'
* );
*/
if (is_array($pars edhdrs[$key]))
{
$parsedhdrs[$key][] = $val;
}
elseif (is_set($parsed hdrs[$key]))
{
$parsedhdrs[$key] = array($parsedhd rs[$key]);
$parsedhdrs[$key][] = $val;
}
else
{
$parsedhdrs[$key] = $val;
}
}

/* Decode body if encoded using quoted printable or base 64. */
if (preg_match('/quoted.printabl e/i', $parsedhdrs['content-type']))
$parsedbody = quoted_printabl e_decode($body) ;
elseif (preg_match('/base64/i', $parsedhdrs['content-type']))
$parsedbody = base64_decode($ body);
else
$parsedbody = $body;

/* Return everything that could possibly be useful to a script. */
return array(
'headers' =$parsedhdrs,
'body' =$parsedbody,
'raw_headers' =$headers_raw,
'raw_body' =$body,
'raw_message' =$string
);
}

/* Debugging */
$message = string2msg(get_ raw_message());
$myaddress = 'me@example.net ';
mail($myaddress , 'Debugging', print_r($messag e, TRUE));
?>

I haven't tested this, but it ought to work. (Probably forgot a semi-colon
or two.)
