imap_expunge() may change order of messages which were loaded using imap_sort(). That means, if you use foreach() on result of imap_sort() function and each pass you move/delete a message and instantly expunge them, next cycle, messages will have different numbers than imap_sort() returned and the script will fail.

@eisbrenner at gidn dot de You shouldn't call imap_expunge until before closing the connection. imap_delete tags a message for deletion, imap_expunge deletes all tagged messages. i.e.: for ($i = 0; $i < $num; $i++) { imap_delete($box, $i); } imap_expunge($box); imap_expunge should not be in your inner loop.
