[PHP-DEV] imap_thread support From: Rob Siemborski (rjs3 <email protected>)
Date: 03/15/01

So I recently came across a need to implement a call to imap_thread from
PHP-space, and being as PHP did not support a call to imap_thread, so I
implemented one that explicitly did a REFERENCES threading, and returned
the thread tree in the form of a hash with three types of entries...

"#.num" which is the IMAP message ID of the message for threadnode ID #
"#.branch" and "#.next" which correspond to the same things in the C
THREADNODE structure and point to the next #.

The tree is rooted at # == 0.

I'm almost certain there has to be a better way to represent the tree in
PHP, but at first glance references didn't seem to be able to do what I
wanted. Also, the function I wrote (though it could trivially be
expanded) only called the REFERENCES method, not the ORDEREDSUBJECT
method.

Attached is a patch against the 4.0.4pl1 source tree, but I don't think
that there should be severe difficulties in applying it to any recent
version. I'm not sure it conforms to all of the PHP coding standards,
but I guess you can consider it a first draft/attempt at a submission.
