Hello all,
imap_sort uses the c-client library to sort messages. This library
currently does not support locale-based sort for foreign languages
(Although it has charset option).
They are working on this(http://www.washington.edu/imap/IMAP-FAQs/#1.12),
but you can use the following function which uses strcoll() for locale-
based sorting.Pease note that this is required for SUBJECT field sorting,
because most of other fields are sorted correctly by imap_sort in any
locale:
function imap_locale_sort($stream,$criteria,$reverse,$locale,$options)
{
if ($criteria!=SORTSUBJECT)
return (imap_sort($stream,$criteria,$reverse,$options));
$unsorted = array();
$sortresult = array();
$MC=imap_check($stream);
$MN=$MC->Nmsgs;
$overview = imap_fetch_overview($stream,"1:$MN",0);
$k=0;
while( list($key,$val) = each($overview))
{
$unsorted[$k]["uid"]=$val->uid;
$unsorted[$k]["subject"]=MIME::decode($val->subject,
NLS::getCharset());
$k++;
}
usort ($unsorted, create_function('$a,$b','setlocale
(LC_ALL,$locale);return strcoll($a["subject"],$b["subject"]);'));
for ($m=0;$m<count($unsorted);$m++)
array_push($sortresult,$unsorted[$m]["uid"]);
if ($reverse)
$sortresult = array_reverse($sortresult);
return $sortresult;
}
Usage example:
$sorted = imap_locale_sort($stream,SORTSUBJECT,0,'fa_IR',0);
