imap_thread support

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. -Rob -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Rob Siemborski * rjs3@andrew.cmu.edu * WRCT 88.3fm - Chief Engineer Andrew Systems Group * Cyert Hall 235 * 412-CMU-TREK -----BEGIN GEEK CODE BLOCK---- Version: 3.12 GCS/IT/CM/CC/PA d- s+: a-- C++++$ UBLS++++$ P+++$ L++(+++) E W- N- o?
