note 104056 added to function.imap-thread

imap_thread() returns threads, but are confined to the current open mailbox you defined in imap_open(). This is not useful for, lets say, getting full threads ( from "Sent Messages" and "Inbox" [took me a day to figure this out]). If you compare threads on Outlook vs gmail.com you will find that Outlook determines threads by subject title, not actual parent > child relationships. Gmail however, seems to get threads right, but does not include mail you send using their web interface in {imap.google.com:993/imap/ssl}Sent Messages . What this means is that threads using php imap won't be perfect for gmail. If you send mail using Outlook (or any mail client), gmail.com does put it in their "Sent Mail". So all in all, threads for PHP imap are not perfect. But I blame the imap specifications (DEAR IMAP GUYS, please add better uids and parent ids. thx Chris) more than PHP So I created the Outlook method for threading (comparing subjects) below: <?php $imap = imap_open('{imap.gmail.com:993/imap/ssl}INBOX', 'youremail@gmail.com', 'yourpassword'); $subject = 'Item b'; $threads = array(); //remove re: and fwd: $subject = trim(preg_replace("/Re\:|re\:|RE\:|Fwd\:|fwd\:|FWD\:/i", '', $subject)); //search for subject in current mailbox $results = imap_search($imap, 'SUBJECT "'.$subject.'"', SE_UID); //because results can be false if(is_array($results)) { //now get all the emails details that were found $emails = imap_fetch_overview($imap, implode(',', $results), FT_UID); //foreach email foreach ($emails as $email) { //add to threads //we date date as the key because later we will sort it $threads[strtotime($email->date)] = $email; } } //now reopen sent messages imap_reopen($imap, '{imap.gmail.com:993/imap/ssl}Sent Messages'); //and do the same thing //search for subject in current mailbox $results = imap_search($imap, 'SUBJECT "'.$subject.'"', SE_UID); //because results can be false if(is_array($results)) { //now get all the emails details that were found $emails = imap_fetch_overview($imap, implode(',', $results), FT_UID); //foreach email foreach ($emails as $email) { //add to threads //we date date as the key because later we will sort it $threads[strtotime($email->date)] = $email; } } //sort keys so we get threads in chronological order ksort($threads); echo '<pre>'.print_r($threads, true).'</pre>'; exit; ?> ---- Server IP: 69.147.83.197 Probable Submitter: 112.204.98.31 ---- Manual Page -- http://www.php.net/manual/en/function.imap-thread.php Edit -- https://master.php.net/note/edit/104056 Del: integrated -- https://master.php.net/note/delete/104056/integrated Del: useless -- https://master.php.net/note/delete/104056/useless Del: bad code -- https://master.php.net/note/delete/104056/bad+code Del: spam -- https://master.php.net/note/delete/104056/spam Del: non-english -- https://master.php.net/note/delete/104056/non-english Del: in docs -- https://master.php.net/note/delete/104056/in+docs Del: other reasons-- https://master.php.net/note/delete/104056 Reject -- https://master.php.net/note/reject/104056 Search -- https://master.php.net/manage/user-notes.php
