imap_rfc822_parse_headers is not supported by HHVM about fetch

I see mention of it here but it doesn't appear to work. We also ran into a need for this function today.

I've been holding off on diving into the HHVM stuff for this particular project until they manage to make the imap extension a bit more stable over there. At the moment it's got quite a few issues.

The imap_rfc822_parse_headers() function is broken anyway, as it ignores custom headers.

Run $message->getRawheaders() and parse the headers with a regexp instead.

Like:

preg_match_all('/([^: ]+): (.+?(?:\r\n\s(?:.+?))*)\r\n/m', $headers, $matches)
$headers = array_combine($matches[1], $matches[2]);

You want to make a pull request? You'll get all sorts of points if you get this working on HHVM.

It would break compat as it would return an array instead of an object, but we could typecast it to (object) I guess
